[0018] The gate chip-on film may be arranged along one side of the radiation detector, and the gate-connecting FPCB and the readout circuit may be arranged together along adjacent sides of the radiation detector where the gate chip-on film is located.

[0019] The aforementioned readout circuit can be implemented using a readout chip-on-film.

[0020] The aforementioned radiation detector may consist of a flexible detector that can be bent.

[0023] The radiation detector for detecting radiation according to the present disclosure includes a flexible detector panel that extends in a first direction and detects radiation incident on a first surface, is located on a second surface facing the first surface of the detector panel, supports the detector panel, and adjusts the bending of the detector panel about a bending axis parallel to a second direction intersecting the first direction, and a front protection portion that is located in a third direction of the detector panel to protect the detector panel, has an area wider than the exposed detector panel so as to cover the detector panel, is at least partially fixed to the support member, is integrally formed, is flexible, and is detachable from the detector panel.

[0024] The material of the front protection portion of the radiation detector of the present disclosure is made of a thin plate having radiation transmittance and resilience, and the thickness of the front protection portion is characterized in that it is 0.1T or more and 1T or less.

[0025] An upper fixing part protrudes upward above the front protection part of the radiation detector of the present disclosure, and a lower fixing part protrudes downward below the front protection part. The upper fixing part and the lower fixing part are screwed to a support member, and the holes formed in the upper fixing part and the lower fixing part are circular holes rather than oblong holes that are long in the left-right direction.

[0026] At least a part of the radiation detector of the present disclosure is located in at least one of the support member and the front protection part in a third direction, covers at least a part of one side of the front protection part, and includes a fixing bracket fixed to the support member. The fixing bracket includes a protection part cover for covering at least a part of one side of the front protection part, a fixing bracket frame that is connected in a first direction of the protection part cover and is in surface contact with the support member so that the fixing bracket does not sway on the support member, and a fixing bracket fixing part that is connected in a second direction of the fixing bracket frame, has a surface perpendicular to the fixing bracket frame, and is coupled to at least one of the lower surface and the upper surface of the support member.

[0027] One side surface of the protection part cover of the radiation detector of the present disclosure is formed to be recessed in a third direction with respect to one side surface of the fixing bracket frame, and the height between one side surface of the protection part cover and one side surface of the fixing bracket frame is greater than or equal to the thickness of the front protection part.

[0028] When the support member of the radiation detector of the present disclosure is expanded, a space is formed between the end of one side of the front protection part and the fixing bracket frame in the first direction. As the support member is bent, the space between the end of one side of the front protection part and the fixing bracket frame in the first direction decreases.

[0029] At least one left fixing part protrudes to the left on the left side of the front protection part of the radiation detector of the present disclosure, and at least one right fixing part protrudes to the right on the right side of the front protection part. The right fixing part and the left fixing part are screwed to the support member, and the left fixing part and the right fixing part have oblong holes that are long in the left-right direction.

[0030] The radiation detector of this disclosure includes a fixing bracket which is fixed to the support member, at least in part to at least one of the support member and the front protective portion in a third direction, covers at least a portion of one side of the front protective portion, the fixing bracket extends in a first direction and includes an upper fixing bracket and a lower fixing bracket, the upper fixing bracket includes an upper detachment prevention portion which protrudes downward to prevent the front protective portion from detaching, and the lower fixing bracket includes a lower detachment prevention portion which protrudes upward to prevent the front protective portion from detaching.

[0031] At least a portion of the four sides of the front protective portion of the radiation detector of this disclosure includes a magnetic coupling portion containing a magnet or a magnetic metal material, and the magnetic coupling portion of the front protective portion is coupled to the magnet or magnetic metal material of the support member, thereby coupling the front protective portion to the support member.

[0032] The radiation detector of this disclosure has a magnet or a magnetic metal material and includes a magnetic coupling portion that is formed along the four sides of the front protective portion and has a hole in the center, and is located in a third direction of the front protective portion and coupling with the magnet or magnetic metal material of the support member to connect the front protective portion to the support member.

[Effects of the Invention]

[0034] According to the present invention, the displacement difference that occurs between the detector panel and the front and rear protective panels when they bend together can be absorbed, thereby enabling stable bending of the radiation detector.

[0035] According to the present invention, by spatially separating the gate-linked FPCB from the gate chip-on-film and arranging it together with the readout chip-on-film along the same side of the TFT radiation detector, it is possible to arrange components without interference during the design of the printed circuit board, and to design a smaller radiation detector.

[0036] Furthermore, by spatially separating the relatively long gate-linked FPCB from the relatively short gate-tip-on-film and positioning it along the other side, the length of the portion leading out from the TFT X-ray detector in the direction in which the gate-tip-on-film is formed can be minimized. This allows the TFT radiation detector to be in maximum contact with the object, such as a pipe, enabling effective imaging. [Brief explanation of the drawing]

[0046] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings, so that those with ordinary skill in the art to which the present invention pertains can easily implement it. However, the present invention can be embodied in a variety of different forms and is not limited to the embodiments described.

[0047] Referring to Figures 1 and 2, the radiation detector 10 according to an embodiment of the present invention is configured to detect radiation and output a corresponding signal. For example, the radiation detector 10 may be a radiation detector that generates an electrical signal from incident X-rays. For example, the radiation detector may be a direct conversion type radiation detector that directly converts X-ray photons into electric charge, or an indirect conversion type radiation detector that converts X-rays into visible light and then converts the visible light photons into electric charge. As is well known, the radiation detector may also include a TFT array containing multiple pixel TFT circuits that generate an electrical signal based on the amount of charge generated. The structure and principles for realizing the basic functions of such a radiation detector are widely known in the art to which the present invention belongs, so a further detailed explanation thereof is omitted.

[0048] As shown in Figure 2, the radiation detector 10 is formed to be flexible, and for this purpose, the parts constituting the radiation detector 10 are formed of a flexible material or structure. Furthermore, the radiation detector 10 according to the embodiment of the present invention can be bent in the opposite direction to the bending direction shown in Figure 2, which means that the radiation detector 10 according to the embodiment of the present invention can be bent in both directions. To aid understanding, Figure 2 shows the radiation detector 10 with some components removed.

[0049] Referring to Figure 3, the radiation detector 10 includes a detector panel 11. For example, as mentioned above, the detector panel 11 is configured to generate electrical signals from X-rays incident in a direct or indirect manner. Specifically, if the detector panel 11 is a direct radiation detector, it may include a photoconductor layer that generates charge upon X-ray incidence, and a TFT array that includes multiple pixel TFT circuits for collecting the charge generated from the photoconductor layer. On the other hand, if the detector panel 11 is an indirect system, it may include a flash layer, a photodiode layer, and a TFT array.

[0050] Such a detector panel 11 may be formed to have a roughly rectangular shape and may include a gate circuit for applying a signal for switching drive of the pixel TFT circuit, and a readout circuit for receiving the output signal of the pixel TFT circuit and outputting it externally. For example, the gate circuit and the readout circuit may be arranged on adjacent sides of the detector panel 11, respectively.

[0051] As mentioned above, the detector panel 11 is formed to bend in both directions, and for this reason, the detector panel 11 can be manufactured by forming the TFT array on a substrate of a flexible synthetic resin material.

[0052] A front protective panel 13 and a rear protective panel 15 are positioned on either side of the detector panel 11. The front protective panel 13 is positioned on the front side of the detector panel 11, i.e., the side from which the detected radiation enters, and the rear protective panel 15 is positioned on the opposite side. Since radiation, such as X-rays, enters the detector panel 11 through the front protective panel 13, the front protective panel 13 may be made of a material that allows X-rays to pass through. Also, as mentioned above, not only the detector panel 11 but also the front protective panel 13 and the rear protective panel 15 are made of a material that can be bent in both directions. The front protective panel 13 and the rear protective panel 15 may be positioned adjacent to the front and rear of the detector panel 11 to perform the function of protecting the detector panel 11, and may also be configured to perform an electrical grounding function. For example, the front protective panel 13 and the rear protective panel 15 may be made of aluminum.

[0053] The radiation detector 10 includes a support member 18 that supports the detector panel 11, the front protection panel 13, and the rear protection panel 15. That is, the detector panel 11, the front protection panel 13, and the rear protection panel 15 are supported by the support member 18 to form a single module. At this time, the detector panel 11, the front protection panel 13, and the rear protection panel 15 are supported by the support member 18 so that they can bend in both directions. In particular, the detector panel 11, the front protection panel 13, and the rear protection panel 15, which are arranged to be adjacent to each other in a stacked configuration, will undergo different displacements when bending, so they are configured to bend in both directions while allowing different displacements from each other.

[0054] The support member 18 is also configured to bend in both directions along with the detector panel 11, the front protective panel 13, and the rear protective panel 15. As illustrated illustrative in Figure 3, the support member 18 includes first and second support sections 187 and 188 arranged to be spaced apart from each other, and a bendable bending section 181 connecting the first and second support sections 187 and 188. The bending section 181 includes a plurality of connecting members 182 that are connected in sequence to enable hinge behavior relative to each other. The bending section 181, consisting of a plurality of hinged connecting members 182, is configured to bend when an external force is applied, as shown in Figure 2.

[0055] The support member 18 may include a fixed support block 184 and a movable support block 183, which are installed on the first and second support sections 187 and 188, respectively. Referring to Figures 3 and 5, the detector panel 11 is supported by the support member 18 by fixing one end to the fixed support block 184 and the other end to the movable support block 183.

[0056] The fixed support block 184 is fixedly fastened to the first support portion 187 and remains fixed to the first support portion 187 even when the radiation detector 10 is bent, while the movable support block 183 is movably fastened to the second support portion 188 so that it can move laterally, i.e., in the Y-axis direction in Figure 3. One side edge of the detector panel 11, for example the edge to which the readout circuit 1030 is connected, can be fixed to the fixed support block 184.

[0057] As a result, as shown in Figures 2 and 7, when the radiation detector 10 bends, the movable support block 183 moves in the direction of the arrow shown in Figure 7. Consequently, when the detector panel 11 bends, the movement of the movable support block 183 and the displacement of one end of the detector panel 11 are possible, thereby allowing the shape change due to the bending of the detector panel 11 to be stable.

[0058] A rear cover 19 can be fixed to the support member 18 to close the space between the first support portion 187 and the second support portion 188, which are located on both sides of the support member 18. In this way, the rear cover 19 covers the rear surface of the rear protective panel 15. The rear cover 19 is also made of a flexible material.

[0059] The front cover 17 is fastened to the support member 18 with the front protective panel 13 positioned in front of it, and the front protective panel 13 and the rear protective panel 15 are supported by the front cover 17 and the support member 18 with the front protective panel 13 and rear protective panel 15 positioned on either side of the detector panel 11, respectively. At this time, the front protective panel 13 and the rear protective panel 15 are supported by the support member 18 in such a manner that the difference in displacement between the front cover 17 and the support member 18 can be absorbed by bending in both directions.

[0060] The front cover 17 may also be formed to have a rectangular annular shape similar to that of the support member 18 described above. The support member 18 may be equipped with a plurality of fastening rods 185 that protrude forward from the edge region, and each fastening rod 185 is inserted into a fastening hole 171 formed in the front cover 17. At this time, a plurality of fastening members 21 can be fastened to each fastening rod 185 to fix the front cover 17 to the fastening rods 185. The plurality of fastening rods 185 may be arranged in order along the edges of the first and second support portions 187 and 188 described above, and along the bending portion 181, as shown in the drawing.

[0061] The front protective panel 13 is interposed between the front cover 17 and the detector panel 11, and the rear protective panel 15 is interposed between the support member 18 and the detector panel 11. At this time, the front protective panel 13 and the rear protective panel 15 are supported by the fastening rod 185 that connects the front cover 17 and the support member 18, respectively.

[0062] The front protective panel 13 and the rear protective panel 15 are each provided with a plurality of fastening slots 131 and 151 formed in their respective edge regions. The fastening slots 131 and 151 of the front protective panel 13 and the rear protective panel 15 may be formed in corresponding positions, and each fastening rod 185 passes through the overlapping fastening slots 131 and 151 of the front protective panel 13 and the rear protective panel 15. At this time, the fastening slots 131 of the front protective panel 13 and the fastening slots 151 of the rear protective panel 15 may be formed to be located outside the area occupied by the detector panel 11. In this way, the front protective panel 13 and the rear protective panel 15 are each supported by the fastening rods 185 that connect the front cover 17 and the support member 18.

[0063] At this time, the fastening rod 185 and the fastening slots 131 and 151 are configured such that the relative movement of the fastening rod 185 is constrained in one direction, but is able to move relative to it in the other direction. For example, the fastening rod 185 and the fastening slots 131 and 151 are configured such that the movement of the fastening rod 185 is substantially constrained in the Z-axis direction within the fastening slots 131 and 151 in Figure 3, but is able to move in the Y-axis direction within the fastening slots 131 and 151. Here, the Y-axis direction can be defined as the width direction of the detector panel 11, and the Z-axis direction can be defined as the height direction of the detector panel 11. For this reason, the fastening slots 131 and 151 can have the form of elongated holes with a length that is longer in the Y-axis direction than in the Z-axis direction, and the fastening rod 185 can have a circular cross-section with a diameter that is approximately the same as the length of the fastening slots 131 and 151 in the Z-axis direction. Since the fastening rod 185, which is fixed to the front cover 17 and the support member 18, is inserted into the elongated fastening slots 131 and 151 of the front protective panel 13 and the rear protective panel 15, when the detector panel 11, the front and rear protective panels 13 and 15, the front cover 17 and the support member 18 bend around the direction aligned with the Z-axis as shown in Figure 2, the fastening rod 185 can move along the long fastening direction of the fastening slots 131 and 151. This allows the difference in displacement between them due to bending to be absorbed, thereby enabling stable bending. Alternatively, the length of the fastening slots 131 and 151 can be adjusted to realize the desired range of bending.

[0064] On the other hand, to set a reference point for bending when the detector panel 11, the front and rear protective panels 13 and 15, the front cover 17, and the support member 18 all bend together, movement-restricting fastening slots 133 and 153 can be formed at corresponding positions on the front protective panel 13 and the rear protective panel 15, respectively. The movement-restricting fastening slots 133 and 153 do not have the shape of elongated holes, but rather have substantially the same shape as the cross-section of the movement-restricting fastening rod 186 inserted therein. As a result, when the movement-restricting fastening rod 186 inserted into the movement-restricting fastening slots 133 and 153 is fully blocked from moving in the Z-axis and Y-axis directions. This fixes the front protective panel 13 and the rear protective panel 15 to the support member 18 at the positions of the movement-restricting fastening slots 133 and 153 when the detector panel 11, the front protective panel 13, and the rear protective panel 15 bend. In this respect, the movement-restricting fastening slots 133 and 153 can be said to form a reference point for bending of the detector panel 11, the front protective panel 13, and the rear protective panel 15. The drawings illustrate the positions of the movement-restricting fastening slots 133 and 153 and the fastening rods 186 inserted therein, but these positions may be changed as needed.

[0065] As described above, the radiation detector 10 according to the embodiment of the present invention may be a direct conversion or an indirect conversion radiation detector. Figure 8 illustrates an example of a direct conversion radiation detector 10, and Figure 9 illustrates an example of an indirect conversion radiation detector.

[0066] Referring to Figure 8, the radiation detector 10 according to one embodiment of the present invention may be a direct-type digital radiation detector that directly converts X-ray photons into electric charge. Furthermore, the radiation detector 10 according to an embodiment of the present invention may be a flexible radiation detector that can be bent.

[0067] The radiation detector 10 may include a detector panel 11. Figure 8 shows a cross-section of the detector panel 11. Referring to Figure 8, according to the radiation detector panel 11 of the embodiment of the present invention, a TFT array 813, a charge collection unit 815, a photoconductor layer 817, and an upper electrode 819 can be sequentially formed on a bendable substrate 811. For example, the substrate 811 may be made of a bendable synthetic resin material, thereby enabling the radiation detector 10 of the embodiment of the present invention to be realized as a flexible detector. Furthermore, the detector panel 11 included in the radiation detector 10 may be a flexible panel.

[0068] When X-rays are incident on the upper electrode 819 while a high voltage from the power supply 821 is applied, the photoconductor layer 817 generates an electric charge. The photoconductor layer 817 can be formed from a material that directly converts X-ray photons into electric charge, i.e., a photoconductor, such as amorphous selenium, lead oxide (PbO), or thallium bromide (HgI2). At this time, an electrical insulating layer 818 can be formed between the upper electrode 819 and the photoconductor layer 817 to electrically insulate them from each other.

[0069] The TFT array 813 includes multiple pixel TFT circuits 823 and can be implemented in the form of a flexible panel. As is well known, the multiple pixel TFT circuits 823 can be arranged in a matrix on a pixel-by-pixel basis, thereby allowing the TFT array 813 to form a rectangular region. Each pixel TFT circuit 823 includes a storage capacitor 8231 and a TFT switching element 8233. The TFT switching element 8233 includes a gate terminal G, a data terminal D, and a source terminal S, the source terminal S being connected to the storage capacitor 8231. The gate terminal G is signal-connected to the gate circuit, i.e., the gate chip-on-film (COF) 1011, via the gate line 8235, and the data terminal D is signal-connected to the readout circuit, i.e., the readout IC chip-on-film 1030, via the data line 8237.

[0070] When an X-ray incident generates charge in the photoconductor layer 817, the positive charge generated is collected in the charge collection unit 815. Furthermore, the positive charge collected in the charge collection unit 815 is stored in the storage capacitor 8231 of the pixel TFT circuit 823. In this process, the amount of charge generated by the photoconductor layer 817 varies depending on the intensity of the incident X-ray, and consequently, the amount of charge stored in the storage capacitor 8231 also varies depending on the intensity of the X-ray. When a gate signal, i.e., a scan signal, is applied to the gate terminal G through the gate line 8235, the TFT switching element 8233 turns on, and an output signal corresponding to the amount of charge stored in the storage capacitor 8231 is output to the data line 8237 through the data terminal D. In this manner, an output signal corresponding to the intensity of the X-ray detected for each pixel is output, and this output signal can be used to generate an X-ray image. On the other hand, although not shown in the drawings, as is well known, a circuit element for initializing the storage capacitor 8231 after the output signal is output by turning on the TFT switching element 8233, such as a switching element, may be connected in parallel with the storage capacitor 8231.

[0071] On the other hand, referring to Figure 9, another embodiment of the present invention, the radiation detector 10, may be an indirect digital radiation detector that converts X-rays into visible light and then converts the photons of visible light into electric charges. For example, the radiation detector 10 may include an indirect detector panel 11. The same drawing numbers are used for parts that are the same as those used in the direct radiation detector described above with reference to Figure 8, and redundant explanations are omitted.

[0072] Referring to Figure 9, the indirect radiation detector 10 includes a scintillator layer 937 that converts incident X-rays into visible light, and a photodiode layer 935 that generates an electric charge in the visible light converted by the scintillator layer 937. The scintillator layer 937 may be formed of a scintillator that emits visible light proportional to the incident X-rays. The photodiode layer 935 may be formed of an amorphous silicon photodiode that converts the visible light emitted from the scintillator layer 937 into an electric charge. Similar to the embodiments described above, the charge generated in the photodiode layer 935 is detected by the TFT array 813.

[0073] The gate circuit 1010 for applying a gate signal to gate line 8235 and the readout circuit 1030 for receiving an output signal from data line 8237 and outputting it externally will be described below with reference to Figure 10.

[0074] Figure 3 illustrates an illustrative plan view of the TFT array 813 of the radiation detector 10, and the TFT array 813 may be configured to have an overall rectangular shape. As mentioned above, the TFT array 813 includes a plurality of pixel TFT circuits 823 arranged in a matrix.

[0075] The gate circuit 1010 is configured to apply a gate signal to a gate line 8235 connected to a pixel TFT circuit 823. According to an embodiment of the present invention, the gate circuit 1010 is composed of two parts: a gate chip-on-film (gate COF) 1011 and a gate-connected FPCB (flexible printed circuit board) 1013. The gate chip-on-film 1011 and the gate-connected FPCB 1013 are arranged along different sides 1001 and 1002 of the radiation detector panel 11, respectively. Here, the sides of the radiation detector panel 11 may be understood as the sides of the rectangular region of the TFT array 813. The gate-connected FPCB 1013 is signal-connected to an external controller via a connector 1014 and receives a drive signal from the controller, which is transmitted to the gate chip-on-film 1011. The gate chip-on-film 1011 generates a gate signal from the received drive signal and applies it to the gate line 8235.

[0076] The readout circuit 1030 is implemented in chip-on-film form and can therefore be referred to as a readout COF. The readout COF 1030 is connected to an external video signal processing unit via connector 1031 and is configured to transmit output signals to the video signal processing unit.

[0077] According to an embodiment of the present invention, the readout COF 1030 can be arranged along one side of the detector panel 11. In this case, the gate chip-on-film 1011 of the gate circuit 1010 can be arranged along one side 1001 of the rectangular detector panel 11, and the gate coupling FPCB 1013 of the gate circuit 1010 and the readout COF 1030 can be arranged along the side 1002 adjacent to the side 1001 of the detector panel 11 on which the gate chip-on-film 1011 is arranged. According to an embodiment of the present invention, considering that the gate coupling FPCB 1013 and the readout COF 1030 must be formed to be relatively long in order to be signal-connected to an external controller or video signal processing unit, and must be equipped with connectors 1014 and 1031 for connection, the gate coupling FPCB 1013 and the readout COF 1030 can be arranged along the same side 1002, thereby significantly reducing the size of the detector panel 11 in the height direction, or vertical direction in Figure 10. As a result, the gate chip-on film 1011 forms a portion that protrudes outside the TFT array 813 in the height direction of the detector panel 11, thereby minimizing the height length of the portion that protrudes outside the TFT array 813, which is the X-ray sensing area. This means that the radiation detector 10, including the detector panel 11, can approach the object very close in the height direction, thereby enabling imaging with the radiation detector 10 positioned very close to the connection point of the T-shaped piping. In addition, interference between the gate chip-on film 1011 and the gate connecting FPCB 1013 can be prevented by arranging them along different sides of the radiation detector.

[0078] Although the above description used a direct radiation detector as an example, it can be recognized that the present invention can also be applied to an indirect radiation detector comprising a TFT array. Furthermore, as mentioned above, the radiation detector according to the embodiment of the present invention may be implemented as a flexible detector that can be bent, or it may be a rigid radiation detector in the form of a TFT formed on a glass substrate.

[0079] Figure 11 is a front view showing a radiation detector according to one embodiment of the present disclosure. Figure 12 is a front view showing a radiation detector according to one embodiment of the present disclosure.

[0080] The radiation detector will be described below with reference to Figures 11 and 12.

[0081] The radiation detector 10 of this disclosure may be a device that detects radiation emitted from a radiation source and transmitted through a subject. The radiation may include at least one of X-rays, gamma rays, and certain ultraviolet rays. The radiation detector 10 can detect radiation and acquire a radiation image of the subject. For example, the radiation image acquired by the radiation detector 10 may include at least one of X-ray images and CT (Computed Tomography) images.

[0082] The radiation detector 10 may include a detector panel 11. Detector panels can be classified into two types based on the method of acquiring electrical signals: a direct conversion type that uses a scintillator to obtain electrical signals indirectly from visible light, and a direct conversion type that uses photoconductors to obtain electrical signals directly from radiation. They can also be classified into three types based on the type of element that generates the electrical signal: a CCD type using a charge-coupled device, a CMOS type using a crystalline silicon CMOS element, and an a-Si type using an amorphous silicon TFT (Thin Film Transistor) substrate.

[0083] The radiation detector 10, including the detector panel 11, is equipped with various sensors and can realize digital image data using electrical signals and positional information of sensors proportional to the amount of incident radiation. The radiation detector 10 can obtain near real-time imaging results, can secure high resolution and a wide dynamic range with relatively low radiation, and the storage and processing of imaging results are simple due to the characteristics of digital data. The radiation detector 10 includes a readout signal unit that reads electrical signals output from a pixel array, and a gate driver that turns on switching elements so that the readout signal unit can read electrical signals. The electrical signals detected by the readout signal unit are converted into image signals through a certain processing process by a controller on the main board and then transmitted to a display device for displaying X-ray images.

[0084] The radiation detector 10 may include the same configuration as at least one of the following: a pixel array, a readout signal section, a gate driver circuit section, and a main board. The readout signal section may be embodied in a number of film-type ROICs (Read out ICs), each ROIC of which may be connected to the main board by a connector.

[0085] The radiation detector 10 may include a photodetector that detects X-rays and generates an electrical signal, and a readout circuit that reads out the generated electrical signal. After processing the electrical signal output from the readout circuit, the control unit can generate X-ray image data that constitutes an X-ray image. The generated X-ray image data may be stored in a storage unit together with (or separately from) detector status information or information related to X-ray imaging.

[0086] In order to sequentially perform the operations of detecting X-ray information with the radiation detector 10 and transmitting it to an external computer, the radiation detector 10 can use a power and data cable that transmits both power (or power supply) and data communication.

[0087] Furthermore, the radiation detector 10 can utilize WiFi and Gigabit Ethernet® for wired / wireless data transmission. Additionally, the control unit of the radiation detector 10 may be connected to a workstation to communicate with it for variables for driving the video sensor, etc.

[0088] The detector panel 11 can be extended in a first direction. In Figure 11, the first direction may be to the left, but it is not limited to this and may be to the right. The detector panel 11 can detect radiation incident on its first surface, where the first surface may mean the front surface of the detector panel 11. The detector panel 11 can be flexible; that is, it can be bent due to its flexibility. If the surface of the object has a rounded surface, the detector panel 11 can be bent to closely adhere to the surface of the object. Because the detector panel 11 is positioned in close contact with the surface of the object, the sharpness of the radiation image can be increased.

[0089] The radiation detector 10 may include a bending support member 18. Although the rear protective panel 15 and rear cover 19 are not shown in Figure 11, at least one of the rear protective panel 15 and rear cover 19 can be positioned between the support member 18 and the detector panel 11.

[0090] The support member 18 can contact a second surface of the detector panel 11 that is opposite to the first surface. The second surface may be the rear surface of the detector panel 11. The support member 18 can support the detector panel 11. As mentioned above, the detector panel 11 is flexible and can be bent, so without the support member 18, it may be difficult to place the detector panel 11 gently against an object. This is because the detector panel 11 is easily deformed by the movement of the object or external force. Therefore, the support member 18 may be configured to support the detector panel 11 so that it maintains a certain shape after it has been bent. The support member 18 can adjust the bending of the detector panel 11 around a bending axis parallel to the second direction that intersects the first direction. That is, because the support member 18 is bent, the detector panel 11 can also be bent. Here, the second direction may be the upward direction. However, it is not limited to this, and the second direction may be the downward direction.

[0091] The support member 18 can include a variety of configurations for the operation of the radiation detector 10. For example, the support member 18 can include at least one of a control unit, a communication unit, an input unit, and an output unit for the operation of the radiation detector 10. Also, as shown in Figure 12, the detector panel 11 may be embedded in the support member 18. However, it is not limited to these.

[0092] The radiation detector 10 may include a front protective section 1130. The front protective section 1130 may be positioned in a third direction relative to the detector panel 11 to protect the detector panel 11, where the third direction may mean the forward direction.

[0093] The front protective portion 1130 can have a larger area than the detector panel 11 exposed from the support member 18 so as to cover the detector panel 11. At least a portion of the front protective portion 1130 can be fixed to the support member 18. The front protective portion 1130 does not have to be fixed to the detector panel 11. Also, only a portion of the front protective portion 1130 can be connected to the support member 18. Therefore, the front protective portion 1130 can be made flexible, and the front protective portion 1130 only protects the detector panel 11, preventing damage to the support member 18 and the detector panel 11. Details of fixing the front protective portion 1130 to the support member 18 will be described later.

[0094] Furthermore, the front protective section 1130 can be formed as a single unit. That is, the front protective section 1130 is not a combination of various components, but can have the shape of a single panel. For example, the front protective section 1130 can be manufactured by cutting or folding a single sheet of a predetermined material. However, it is not limited to this.

[0095] The front protective section 1130 can be flexible. Therefore, the front protective section 1130 can also bend due to bending of at least one of the detector panel 11 and the support member 18. Furthermore, the front protective section 1130 may be detachable from the detector panel 11.

[0096] The detector panel 11 may already be covered by a housing to protect it. Therefore, the detector panel 11 can also be protected from external impacts by the housing. The front protection section 1130 may be an additional means of protecting the detector panel 11 in addition to the housing. The housing for protecting the detector panel 11 may include at least one of the front protection panel 13 and the front cover 17. The front protection section 1130 may be configured to be used in addition to the front protection panel 13 and the front cover 17. The front protection section 1130 may be positioned in front of the front cover 17. However, it is not limited to this, and the front protection section 1130 can replace at least one of the front protection panel 13 and the front cover 17. That is, a radiation detector may not have at least one of the front protection panel 13 and the front cover 17, but may have the front protection section 1130.

[0097] In the following explanation, the front protection panel 13 and the front cover 17 will be omitted in order to focus on the front protection section 1130. However, it should be understood that at least one of the front protection panel 13 and the front cover 17 may be located between the front protection section 1130 and the detector panel 11.

[0098] Since the housing for protecting the detector panel 11 is bonded to the detector panel 11, if there is a problem with the material protecting the detector panel 11, the detector panel 11 itself may need to be replaced. In particular, if the object being examined is rough or the radiation detector 10 is used in a harsh environment, the likelihood of scratches occurring on the detector panel 11 increases, which may lead to a shorter replacement cycle for the radiation detector 10. The radiation detector 10 of this disclosure includes a replaceable front protective section 1130, which can contact or approach the object being examined instead of the detector panel 11. Therefore, scratches will occur on the front protective section 1130 rather than the detector panel 11, and the user can easily maintain the radiation detector 10 by simply replacing the front protective section 1130. In other words, the radiation detector 10 of this disclosure can further increase the durability of the radiation detector 10 by providing a detachable front protective section 1130.

[0099] The thickness of the front protective section 1130 can be between 0.1T and 1T. The material of the front protective section 1130 can be a radiation-transmitting material. Furthermore, the material of the front protective section 1130 is a resilient material, meaning it can be restored to its original state even if bent by external force. If the thickness of the front protective section 1130 exceeds 1.0T, the transmittance and yield strength decrease, making it difficult to use in a bendable radiation detector 10 and potentially degrading the quality of the radiation image. If the thickness of the front protective section 1130 is 0.1T or less, it may not only fail to function as a protective section but also have reduced durability. The front protective section 1130 can have a transmittance of 85% or more. If the transmittance of the front protective section 1130 falls below 85%, high-energy radiation must be irradiated to acquire the radiation image, potentially leading to excessive energy exposure that could negatively affect the circuit board installed in the detector and increase the radiation exposure of the subject. When using a front protection section 1130 with a tension of 1T or more to protect the circuit board from excessive energy exposure, problems may arise where the front protection section 1130 is damaged or fails to recover during bending. Furthermore, the yield strength of the front protection section 1130 may be between 20 MPa and 30 MPa. For example, the yield strength of the front protection section 1130 may be 23 MPa. A front protection section 1130 with such physical properties can maintain appropriate elasticity during bending, enabling repeated bending and flattening motions without affecting the TFTs of the radiation detector 10 and the circuit board.

[0100] The material of the front protection part 1130 may be at least one of stainless steel sheet material, copper sheet material, or carbon tool steel. However, it is not limited to these, and the material of the front protection part 1130 may be a composite sheet material which is a mixture of at least one of stainless steel material, copper material, and carbon tool steel. The carbon tool steel that can be used as the front protection part 1130 may be one of SK1, SK2, SK3, SK4, SK5, SK6, and SK7. Post-treatment may be carried out on the material in order to increase the surface hardness of the front protection part 1130. For example, heat treatment, PVD, DLC, etc. can be carried out on the material. The front protection part 1130 can return to its original state while maintaining its flexibility by utilizing the material and thickness described above. In addition, since it allows radiation to pass through, it can have almost no effect on radiation images. Furthermore, the front protection part 1130 can ensure sufficient strength to adequately protect the detector panel 11. As described above, the material and thickness of the front protective section 1130 ensure at least one of the optimal bendability, resilience, and radiotransparency of the front protective section 1130, which has been experimentally proven. Furthermore, since only the front protective section 1130 is damaged when external material applies force to the detector, replacing only the front protective section 1130 allows the detector to maintain the same performance as a new one, thus increasing user convenience.

[0101] Referring to Figure 11, the front protective portion 1130 may include an upper fixing portion 1131. The upper fixing portion 1131 may also be formed to protrude above the front protective portion 1130. The front protective portion 1130 may also include a lower fixing portion 1132. The lower fixing portion 1132 may also be formed to protrude below the front protective portion 1130. Holes may be formed in the upper fixing portion 1131 and the lower fixing portion 1132. The holes formed in the upper fixing portion 1131 and the lower fixing portion 1132 may be circular holes rather than elongated holes. However, they are not limited to this. The upper fixing portion 1131 and the lower fixing portion 1132 can be screw-connected to the support member 18. That is, screws can pass through the upper fixing portion 1131 and the lower fixing portion 1132 to connect to the support member 18.

[0102] The upper fixing portion 1131 and the lower fixing portion 1132 allow the front protective portion 1130 to be positioned in the center left to right. That is, the distance from the upper fixing portion 1131 and the lower fixing portion 1132 to the left edge of the front protective portion 1130 and the distance from the upper fixing portion 1131 and the lower fixing portion 1132 to the right edge of the front protective portion 1130 may be the same. However, it is not limited to this.

[0103] The upper fixing portion 1131 and the lower fixing portion 1132 can prevent the front protective portion 1130 from moving away from either the detector panel 11 or the support member 18. Furthermore, since the upper fixing portion 1131 and the lower fixing portion 1132 are formed to protrude from the front protective portion 1130, deformation of the front protective portion 1130 can be minimized. For example, if force is applied to the front protective portion 1130, the force will be applied to the fixed upper fixing portion 1131 and the lower fixing portion 1132, and since the deformation of the upper fixing portion 1131 and the lower fixing portion 1132 has little effect on the generation of the radiation image, even if deformation occurs in the upper fixing portion 1131 and the lower fixing portion 1132, there will be no problem in using the radiation detector 10.

[0104] Furthermore, by minimizing the connection between the front protective section 1130 and the support member 18, damage to the radiation detector 10 by the front protective section 1130 can be minimized. This is because, as mentioned above, the front protective section 1130 can come into contact with and approach the object, and therefore can be subjected to significant external forces. Since such external forces are not transmitted to the detector panel 11 or the support member 18 through the front protective section 1130, damage to the radiation detector 10 can be minimized.

[0105] Furthermore, since the front protective section 1130 is in close contact with the detector panel 11 by the upper fixing section 1131 and the lower fixing section 1132, the image from the radiation detector 10 can be prevented from being distorted by the front protective section 1130.

[0106] Referring to Figure 12, the radiation detector 10 may include a fixing bracket 1210. The fixing bracket 1210 may include a left fixing bracket 1210 and a right fixing bracket 1210. At least a portion of the fixing bracket 1210 may be positioned in at least one third direction of the support member 18 and the front protection part 1130. The third direction may mean the front. The fixing bracket 1210 may cover at least a portion of one side of the front protection part 1130. For example, the left fixing bracket 1210 may cover at least a portion of the left side of the front protection part 1130. Also, the right fixing bracket 1210 may cover at least a portion of the right side of the front protection part 1130. The fixing bracket 1210 may be fixed to the support member 18.

[0107] Figure 13 is a diagram illustrating a fixing bracket according to one embodiment of the present disclosure. Figure 14 is also a diagram illustrating a fixing bracket according to one embodiment of the present disclosure.

[0108] Figure 13 shows a perspective view of the radiation detector 10. Figure 14 shows a cross-section of the radiation detector 10. More specifically, Figure 14 shows a cross-section of the fixing bracket 1210.

[0109] Referring to Figures 13 and 14, the fixing bracket 1210 may include a protective cover 1310. The protective cover 1310 can cover at least a portion of one side of the front protective part 1130. For example, the protective cover 1310 can cover at least a portion of the left side of the front protective part 1130. Also, the protective cover 1310 can cover at least a portion of the right side of the front protective part 1130. Referring to Figure 14, the front protective part 1130 can be positioned between the protective cover 1310 and the support member 18. In Figure 13, the fixing bracket 1210 is separated by a dotted line, but this is only for illustrative purposes, and the actual fixing bracket 1210 does not have a dotted line drawn on it.

[0110] Referring to Figures 13 and 14, the fixing bracket 1210 may include a fixing bracket frame 1320. The fixing bracket frame 1320 may be connected to the protective cover 1310 in a first direction. The first direction may be, for example, the left side. However, it is not limited to this, and the first direction may be the right side. The fixing bracket frame 1320 can be positioned to the left of the protective cover 1310 for the left fixing bracket 1210. The fixing bracket frame 1320 can be positioned to the right of the protective cover 1310 for the right fixing bracket 1210. The fixing bracket frame 1320 can be in surface contact with the support member 18 so that the fixing bracket 1210 does not sway on the support member 18.

[0111] Referring to Figure 13, the fixing bracket 1210 may include a fixing bracket fixing portion 1330. The fixing bracket fixing portion 1330 may be connected to the fixing bracket frame 1320 in a second direction, or to the opposite direction of the fixing bracket frame 1320, where the second direction may be upward. However, it is not limited to this, and the second direction may be downward. The fixing bracket fixing portion 1330 may have a surface perpendicular to the fixing bracket frame 1320. That is, if the fixing bracket frame 1320 is parallel to the front surface of the support member 18, the fixing bracket fixing portion 1330 may be parallel to the lower or upper surface of the support member 18. The fixing bracket fixing portion 1330 may be connected to at least one of the lower and upper surfaces of the support member 18. The fixing bracket fixing portion 1330 may be screw-connected to the support member 18.

[0112] Referring to Figure 14, one side of the protective cover 1310 may be formed to be recessed in a third direction relative to one side of the fixed bracket frame 1320. The third direction may mean forward. The reason why one side of the protective cover 1310 is recessed in a third direction relative to one side of the fixed bracket frame 1320 may be to accommodate space for the protective cover 1310 to house the front protective section 1130. The height 1410 between one side of the protective cover 1310 and one side of the fixed bracket frame 1320 may be greater than or equal to the thickness of the front protective section 1130. By covering at least a portion of the front protective section 1130 in this way, the protective cover 1310 can help the front protective section 1130 bend and return to its original state without problems. It can also help maintain a constant distance between the front protective section 1130 and the detector panel 11. That is, the left and right sides of the front protective section 1130 can be prevented from moving away from the detector panel 11.

[0113] Furthermore, when the support member 18 is spread out as shown in Figures 13 and 14, a space 1420 may be formed between one end of the front protection portion 1130 and the fixed bracket frame 1320 in the first direction. Here, the first direction may mean the left direction. Also, unlike Figures 13 and 14, the more the support member 18 is bent, the more the space 1420 between one end of the front protection portion 1130 and the fixed bracket frame 1320 in the first direction may gradually decrease. However, it is not limited to this, and unlike Figures 13 and 14, the more the support member 18 is bent, the more the space 1420 between one end of the front protection portion 1130 and the fixed bracket frame 1320 in the first direction may gradually increase. When the support member 18 is spread out in this manner, a space 1420 is formed between one end of the front protective section 1130 and the fixed bracket frame 1320 in the first direction, so that even if the support member 18 is bent, the protective section cover 1310 can cover the front protective section 1130 without any problems.

[0114] Figure 15 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.

[0115] Figures 11 to 14 illustrate an embodiment in which the fixing portion included in the front protective section 1130 is located in the center of the left and right sides. However, it is not limited to this. As shown in Figure 15, the fixing portion of the front protective section 1130 can be located at a location other than the center of the left and right sides of the front protective section 1130. For example, the front protective section 1130 may include upper fixing portions 1510, 1520, 1530, and 1540. Also, the front protective section 1130 may include lower fixing portions 1550, 1560, 1570, and 1580.

[0116] Figure 15 illustrates a configuration that includes four upper fixing parts 1510, 1520, 1530, and 1540 on the upper side and four lower fixing parts 1550, 1560, 1570, and 1580 on the lower side. However, it is not limited to this configuration. There may be two or more upper fixing parts. Similarly, there may be two or more lower fixing parts. Furthermore, the upper fixing parts 1510, 1520, 1530, and 1540 and the lower fixing parts 1550, 1560, 1570, and 1580 may include elongated holes rather than circular holes. However, it is not limited to this configuration. When the configuration includes multiple upper and lower fixing parts in this way, the front protection part 1130 can be firmly fixed to the support member 18. Therefore, it is possible to prevent the front protection part 1130 from swaying relative to the support member 18. In addition, the distance between the front protection part 1130 and the detector panel 11 can be maintained at a constant level. Therefore, the image from the radiation detector 10 can be prevented from being distorted by the front protection unit 1130.

[0117] Figure 16 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.

[0118] The front protective section 1130 may include left-side fixing sections 1610, 1620 and right-side fixing sections 1630, 1640. At least one left-side fixing section 1610, 1620 may be formed projecting to the left on the left side of the front protective section 1130. Also, at least one right-side fixing section 1630, 1640 may be formed projecting to the right on the right side of the front protective section 1130. The right-side fixing sections 1630, 1640 and the left-side fixing sections 1610, 1620 can be screw-connected to the support member 18. The left-side fixing sections 1610, 1620 and the right-side fixing sections 1630, 1640 may have elongated holes that are long from side to side.

[0119] When the front protection unit 1130 includes the left fixing units 1610 and 1620 and the right fixing units 1630 and 1640, the front protection unit 1130 can be firmly fixed to the support member 18. Therefore, it is possible to prevent the front protection unit 1130 from shaking relative to the support member 18. In addition, the distance between the front protection unit 1130 and the detector panel 11 can be kept constant. Therefore, the image of the radiation detector 10 can be prevented from being distorted by the front protection unit 1130. Furthermore, the right fixing units 1630 and 1640 and the left fixing units 1610 and 1620 can prevent deformation of the front protection unit 1130.

[0120] In Figure 15, the front protective section 1130 includes upper fixing parts 1510, 1520, 1530, 1540 and lower fixing parts 1550, 1560, 1570, 1580. Also, in Figure 16, the front protective section 1130 includes left fixing parts 1610, 1620 and the right fixing parts 1630, 1640. Combining these, the front protective section 1130 can include upper fixing parts 1510, 1520, 1530, 1540, lower fixing parts 1550, 1560, 1570, 1580, left fixing parts 1610, 1620, and the right fixing parts 1630, 1640. When the front protective section 1130 includes upper fixing sections 1510, 1520, 1530, 1540, lower fixing sections 1550, 1560, 1570, 1580, left-side fixing sections 1610, 1620, and right-side fixing sections 1630, 1640, the front protective section 1130 can be firmly fixed to the support member 18. Therefore, it is possible to prevent the front protective section 1130 from shaking relative to the support member 18.

[0121] Figure 17 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.

[0122] Referring to Figure 17, similar to Figure 16, the front protection unit 1130 can include left-side fixing parts 1610, 1620 and right-side fixing parts 1630, 1640. In addition, the front protection unit 1130 can include an upper bracket 1710 and a lower bracket 1720. The upper bracket 1710 and the lower bracket 1720 can prevent the front protection unit 1130 from lifting away from the detector panel 11 and the support member 18.

[0123] The upper bracket 1710 and the lower bracket 1720 can be extended vertically. One side of the upper bracket 1710 is screw-connected to the support member 18, and the other side can contact the front protection part 1130. Therefore, the upper side of the front protection part 1130 can be fixed by the upper bracket 1710. The other side of the lower bracket 1720 is screw-connected to the support member 18, and one side can contact the front protection part 1130. Therefore, the lower side of the front protection part 1130 can be fixed by the lower bracket 1720. Unlike Figure 11, the upper and lower sides of the front protection part 1130 are not fixed to the support member 18, but are fixed by frictional force from the upper bracket 1710 and the lower bracket 1720, so that the front protection part 1130 can move slightly relative to the support member 18, thus preventing deformation of the front protection part 1130 due to pendulum. Furthermore, since the upper bracket 1710 and the lower bracket 1720 can rotate around an axis extending in the front-to-back direction to detach the front protection part 1130 from the support member 18, the ease of assembly of the front protection part 1130 may be improved. Also, since the front protection part 1130 can be moved to the left or right side and detached from the support member 18 while the upper bracket 1710 and the lower bracket 1720 remain stationary, the ease of assembly of the front protection part 1130 may also be improved.

[0124] Figure 18 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.

[0125] The radiation detector 10 may include fixing brackets 1810 and 1820. At least a portion of the fixing brackets 1810 and 1820 may be positioned in at least one third direction of the support member 18 and the front protective portion 1130. The third direction may be forward, but is not limited to this, and may be rearward. The fixing brackets may extend in a first direction. The first direction may be to the left, but is not limited to this, and may be to the right. The fixing brackets 1810 and 1820 may include an upper fixing bracket 1810 and a lower fixing bracket 1820.

[0126] The fixing brackets 1810 and 1820 can cover at least a portion of one side of the front protective section 1130. For example, the upper fixing bracket 1810 can cover at least a portion of the upper side of the front protective section 1130. Also, the lower fixing bracket 1820 can cover at least a portion of the lower side of the front protective section 1130. The fixing brackets 1810 and 1820 can be fixed to the support member 18. For example, the fixing brackets 1810 and 1820 can be screw-connected to the support member 18.

[0127] The upper fixing bracket 1810 may include upper detachment prevention parts 1811, 1812, and 1813 that protrude downward to prevent the front protective part 1130 from detaching. Figure 18 shows three upper detachment prevention parts 1811, 1812, and 1813, but is not limited to this, and there may be two or more upper detachment prevention parts. The left-right length of the upper detachment prevention parts 1811, 1812, and 1813 may become shorter as they move towards the center of the front protective part 1130, and longer as they move towards the left or right side of the front protective part 1130. For example, the left-right length of the upper detachment prevention part 1812 located in the center may be shorter than the left-right length of the upper detachment prevention part 1811 located on the left and the upper detachment prevention part 1813 located on the right. In this way, the lengths of the upper detachment prevention parts 1811, 1812, and 1813 become shorter towards the center of the front protection part 1130, which can reduce the deformation of the front protection part 1130. In addition, the increased flexibility of the front protection part 1130 allows the surface of the radiation detector 10 to come into close contact with the surface of a round object.

[0128] The lower fixing bracket 1820 may include lower detachment prevention parts 1821, 1822, and 1823 that protrude upward to prevent the front protective part 1130 from detaching. Figure 18 shows three lower detachment prevention parts 1821, 1822, and 1823, but is not limited to this, and there may be two or more lower detachment prevention parts. The left-right lengths of the lower detachment prevention parts 1821, 1822, and 1823 may become shorter as they move towards the center of the front protective part 1130, and longer as they move towards the left or right side of the front protective part 1130. For example, the left-right length of the lower detachment prevention part 1822 located in the center may be shorter than the left-right lengths of the lower detachment prevention part 1821 located on the left and the lower detachment prevention part 1823 located on the right. In this way, the lengths of the lower detachment prevention parts 1821, 1822, and 1823 become shorter towards the center of the front protection part 1130, which can reduce the deformation of the front protection part 1130. In addition, the increased flexibility of the front protection part 1130 allows the surface of the radiation detector 10 to come into close contact with the surface of a round object.

[0129] Figure 19 may be a drawing illustrating the connection between the support member 18 and the front protective part according to one embodiment of the present disclosure.

[0130] Referring to Figure 19, the support member 18 may be connected to an upper fixing bracket 1810 and a lower fixing bracket 1820. The front protection part 1130 may be connected to the support member 18 by sliding along the upper fixing bracket 1810 and the lower fixing bracket 1820. The front protection part 1130 may be guided by the upper fixing bracket 1810 and the lower fixing bracket 1820. In addition, the front protection part 1130 may be prevented from detaching from the support member 18 by upper detachment prevention parts 1811, 1812, 1813 and lower detachment prevention parts 1821, 1822, 1823.

[0131] The upper detachment prevention parts 1811, 1812, 1813 and the lower detachment prevention parts 1821, 1822, 1823 contact the front protection part 1130 and can fix the front protection part 1130 to the support member 18. The rear surfaces of the upper detachment prevention parts 1811, 1812, 1813 and the lower detachment prevention parts 1821, 1822, 1823 that contact the front protection part 1130 can include an elastic material. For example, the elastic material can include at least one of rubber, urethane, and silicone. The upper detachment prevention parts 1811, 1812, 1813 and the lower detachment prevention parts 1821, 1822, 1823 contact the front protection part 1130 and can prevent the front protection part 1130 from detaching from the support member 18 by frictional force. However, this is not limited to this, and the upper detachment prevention parts 1811, 1812, 1813 and the lower detachment prevention parts 1821, 1822, 1823 do not need to be in contact with the front protection part 1130.

[0132] According to the radiation detector 10 in Figure 19, the user can fix the front protective part 1130 to the support member 18 simply by sliding the front protective part 1130 along the upper fixing bracket 1810 and lower fixing bracket 1820 of the support member 18, thus increasing convenience.

[0133] Figure 20 is a drawing illustrating an additional embodiment of the front protection portion according to one embodiment of the present disclosure.

[0134] Figure 20 can show a front protective section 1130 combining Figures 15 and 16. Referring to Figures 15, 16, and 20, the front protective section 1130 may include upper fixing sections 1510, 1520, 1530, and 1540. The front protective section 1130 may also include lower fixing sections 1550, 1560, 1570, and 1580. Furthermore, the front protective section 1130 may include left fixing sections 1610, 1620 and right fixing sections 1630 and 1640.

[0135] The upper fixing parts 1510, 1520, 1530, 1540, the lower fixing parts 1550, 1560, 1570, 1580, the right fixing parts 1630, 1640, and the left fixing parts 1610, 1620 can be screw-connected to the support member 18. The upper fixing parts 1510, 1520, 1530, 1540, the lower fixing parts 1550, 1560, 1570, 1580, the left fixing parts 1610, 1620, and the right fixing parts 1630, 1640 can have elongated holes that are long from side to side. Therefore, the front protective part 1130 can be connected to the support member 18 so that it is movable from side to side. Since the front protective part 1130 is movable from side to side relative to the support member 18, the front protective part 1130 can not be deformed even if the process of bending and unfolding the front protective part 1130 is repeated. Furthermore, the front protective section 1130 can be firmly connected to the support member 18 by the upper fixing sections 1510, 1520, 1530, 1540, the lower fixing sections 1550, 1560, 1570, 1580, the left fixing sections 1610, 1620, and the right fixing sections 1630, 1640.

[0136] Figure 21 may be a drawing illustrating a screw coupling according to one embodiment of the present disclosure.

[0137] As described above, the front protective portion 1130 can be screw-connected to the support member 18. That is, the screw can pass through the hole in the front protective portion 1130 and be connected to the support member 18.

[0138] Referring to Figure 21(A), at least one of the upper fixing parts 1510, 1520, 1530, 1540, the lower fixing parts 1550, 1560, 1570, 1580, the left fixing parts 1610, 1620, and the right fixing parts 1630, 1640 can have elongated holes that are longer in the left-right direction. Therefore, even when the screw 2110 is connected, the front protective part 1130 can move left and right relative to the support member 18. Because the front protective part 1130 can move left and right relative to the support member 18, the front protective part 1130 can avoid putting stress on the detector panel 11 and the support member 18 when the support member 18 is bent. The durability of the radiation detector 10 can be increased.

[0139] Referring to Figure 21(B), at least one of the upper fixing parts 1510, 1520, 1530, 1540, the lower fixing parts 1550, 1560, 1570, 1580, the left fixing parts 1610, 1620, and the right fixing parts 1630, 1640 can have a circular hole. The diameter of the circular hole may be larger than the diameter of the screw 2120. Here, the screw 2120 may mean the part in which the threads are formed. The diameter of the circular hole may be 1.5 times or more and 2 times or less than the diameter of the screw 2120. Therefore, the front protective part 1130 can move left, right, up, and down relative to the support member 18. Because the front protective part 1130 can move left, right, up, and down relative to the support member 18, the front protective part 1130 can avoid putting stress on the detector panel 11 and the support member 18 when the support member 18 is bent. As shown in Figure 21(B), the diameter of the screw head may be larger than the diameter of at least one of the circular holes among the upper fixing parts 1510, 1520, 1530, 1540, the lower fixing parts 1550, 1560, 1570, 1580, the left fixing parts 1610, 1620, and the right fixing parts 1630, 1640.

[0140] Figure 22 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure. Figure 23 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.

[0141] The front protective section 1130 may include a magnetic coupling section. The magnetic coupling section may be located on the front or rear surface of the front protective section 1130. The magnetic coupling section may be located on at least part of the four sides of the front protective section 1130. The magnetic coupling section may include a magnet or a magnetic metal material.

[0142] The magnetic coupling portion of the front protection portion 1130 can be coupled to the magnet or magnetic metal material of the support member 18. Therefore, the front protection portion 1130 can be coupled to the support member 18. When using the magnetic coupling portion in this way, the front protection portion 1130 and the support member 18 can be coupled simply by placing the front protection portion 1130 on the support member 18, making the assembly of the front protection portion 1130 and the support member 18 very easy. Furthermore, by roughly aligning the positions of the front protection portion 1130 and the support member 18, the front protection portion 1130 will be coupled to the support member 18 in a specific direction and position by magnetic force, which can increase user convenience. Alternatively, the polarity of the magnet may be used to ensure that the front protection portion 1130 is coupled to the support member 18 only when it is positioned in a specific direction.

[0143] Figure 22(A) shows the magnetic coupling portion 2210. The magnetic coupling portion 2210 may include at least one of the left magnetic coupling portion 2211, the upper magnetic coupling portion 2212, the right magnetic coupling portion 2213, and the lower magnetic coupling portion 2214. The magnetic coupling portion 2210 may be bonded to the rear surface of the front protective portion 1130. The magnetic force between the magnetic coupling portion 2210 and the support member 18 allows the front protective portion 1130 to be coupled to the support member 18.

[0144] However, the magnetic coupling portion 2210 does not have to be bonded to the front protective portion 1130. Referring to Figure 22(B), the user can place the front protective portion 1130 on the support member 18. The front protective portion 1130 may be movable in front of the support member 18. At this time, the magnetic coupling portion 2210 can be positioned in front of the front protective portion 1130. The magnetic coupling portion 2210 can be coupled to the support member 18 by magnetic force. The front protective portion 1130 between the magnetic coupling portion 2210 and the support member 18 can be fixed to the support member 18 by friction.

[0145] Figure 23(A) shows the magnetic coupling portion 2310. The magnetic coupling portion 2310 can be bonded to the rear surface of the front protective portion 1130. The magnetic force between the magnetic coupling portion 2310 and the support member 18 allows the front protective portion 1130 to be coupled to the support member 18.

[0146] However, the magnetic coupling portion 2310 does not have to be bonded to the front protective portion 1130. The magnetic coupling portion 2310 may have a magnet or a magnetic metal material. The magnetic coupling portion 2310 may be formed along the four sides of the front protective portion. The magnetic coupling portion 2310 may have a hole 2320 in the center. Referring to Figure 23(B), the magnetic coupling portion 2310 may be located in a third direction of the front protective portion 1130. The third direction may mean the front. The magnetic coupling portion 2310 can be coupled to the magnet or magnetic metal material of the support member 18 to bond the front protective portion 1130 to the support member 18. The front protective portion 1130 between the magnetic coupling portion 2310 and the support member 18 may be fixed to the support member 18 by friction.

[0147] The radiation detector 10 may include a control unit and a sensor unit. The sensor unit may be a sensor that senses a magnetic field. The sensor unit may be located on the support member 18. The control unit can sense whether the magnetic coupling units 2210 and 2310 are coupled to the support member 18 based on the signal from the sensor unit. That is, if the sensor unit senses a magnetic flux greater than or equal to the critical magnetic flux, the control unit can determine that the magnetic coupling units 2210 and 2310 are coupled to the support member 18. Also, if the sensor unit senses a magnetic force greater than or equal to the critical magnetic force, the control unit can determine that the magnetic coupling units 2210 and 2310 are coupled to the support member 18. Also, if the sensor unit senses a magnetic flux less than the critical magnetic flux, the control unit can determine that the magnetic coupling units 2210 and 2310 are not coupled to the support member 18. The fact that the magnetic coupling parts 2210 and 2310 are coupled to the support member 18 may mean that the front protection part 1130 is also coupled to the support member 18. The support member 18 can include multiple sensor parts. The control unit can determine that the magnetic coupling parts 2210 and 2310 are coupled to the support member 18 only if the magnetic flux measured by all of the multiple sensor parts is greater than or equal to the critical magnetic flux.

[0148] Figure 24 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.

[0149] Referring to Figure 24(A), the front protection section 1130 may include front protection section connecting sections 2411, 2412, 2413, and 2414 located on at least one of the upper left, upper right, lower left, and lower right sides. The front protection section connecting sections 2411 and 2412 located on the upper left and upper right sides may extend upward from the front protection section 1130. The front protection section connecting sections 2413 and 2414 located on the lower left and lower right sides may extend downward from the front protection section 1130.

[0150] Referring to Figure 24(A), the front protection section 1130 may include front protection section fixing sections 2421, 2422, 2423, and 2424. The front protection section fixing sections 2421, 2422, 2423, and 2424 may be connected to front protection section connecting sections 2411, 2412, 2413, and 2414. The front protection section fixing sections 2421, 2422, 2423, and 2424 may be configured to connect the front protection section 1130 to the support member 18. Furthermore, the front protection section fixing sections 2421, 2422, 2423, and 2424 may have surfaces perpendicular to the front protection section. The upper left front protection section fixing section 2421 may be screw-connected to the left side of the upper surface of the support member 18. The upper right front protection section fixing section 2422 may be screw-connected to the right side of the upper surface of the support member 18. The lower left front protection fixing part (2423) can be screw-connected to the left side of the lower surface of the support member 18. The lower right front protection fixing part (2SS424) can be screw-connected to the right side of the lower surface of the support member 18. At least one elongated hole extending to the left and right may be formed in the front protection fixing parts 2421, 2422, 2423, and 2424. The elongated hole allows the front protection part 1130 to move left and right relative to the support member 18, so that the front protection part 1130 does not put stress on the detector panel 11 and the support member 18 when the support member 18 is bent. The durability of the radiation detector 10 can be increased.

[0151] When using a radiation detector outdoors, wireless communication may be necessary. In this case, if the detector does not include a communication module, it can only communicate via wired communication, which has the disadvantage of requiring a cable to connect to an external device. Furthermore, if the cable length is increased depending on the usage environment, problems may arise with the reliability of data transmission through the cable. Therefore, a wireless module to support wireless communication may be connected to a wired radiation detector. Below, Figures 25 to 26 will be used to describe a wireless module according to one embodiment of this disclosure.

[0152] Figure 25 is a block diagram showing a wireless module according to one embodiment of the present disclosure.

[0153] The radiation detector 10 may further include a wireless module 2510. The wireless module 2510 may be electrically connected to a support member 18. For example, the wireless module 2510 may be connected to the support member 18 by a cable. The cable may include at least one of a power cable and a communication cable. The power cable and the communication cable may be embodied in different lines, but are not limited to this, and the same line may serve the roles of both the power cable and the communication cable. For example, the communication cable may serve the role of the power cable. Generally, power cables are thick, so the communication cable can handle both power supply and communication, significantly reducing the volume of the cable.

[0154] The wireless module 2510 can supply power to the radiation detector 10. More specifically, the wireless module 2510 can supply power to the radiation detector 10 through a power cable. More specifically, the wireless module 2510 includes a battery or power supply unit and can supply electrical energy to the radiation detector 10 through a power cable. However, it is not limited to this, and the radiation detector 10 may also supply electrical energy to the wireless module 2510 through a power cable.

[0155] The wireless module 2510 can supply the electrical energy that the radiation detector 10 uses for communication. Therefore, the process of connecting an additional power supply to the radiation detector 10 for communication can be eliminated.

[0156] Furthermore, the wireless module 2510 can support wireless communication with the external device 2520. More specifically, the radiation detector 10 can communicate with the wireless module 2510 via a communication cable. The radiation detector 10 can transmit data to the external device 2520 based on the wireless module 2510. For example, the radiation detector 10 can transmit data to the wireless module 2510, and the wireless module 2510 can communicate wirelessly with the external device 2520. The data that the radiation detector 10 transmits to the wireless module 2510 may be video-related data. The external device 2520 can receive the data and display the video. The external device 2520 may include at least one of an external controller and an external computer. The external computer may be at least one of a PC, tablet, and smartphone. Also, the radiation detector 10 can receive data from the external device 2520 based on the wireless module 2510. For example, the wireless module 2510 can receive data from the external device 2520. The wireless module 2510 can transmit data received from the external device 2520 to the radiation detector 10 via a communication cable. The data received from the external device 2520 may be command signals for controlling the radiation detector 10.

[0157] Figure 26 is a diagram illustrating an example related to the installation configuration of a wireless module according to one embodiment of the present disclosure.

[0158] Referring to Figure 26, the radiation detector 10 may include a fixing band 2610. The fixing band 2610 can connect one side and the other side of the support member 18. The object 2620 may be surrounded by the fixing band 2610 and the radiation detector 10. Thus, the radiation detector 10 can capture images of the object 2620 while remaining movably fixed to the object 2620. The fixing band 2610 may be made of an elastic material. Also, coupling portions may be formed on one side and the other side of the fixing band 2610 for connecting to the support member 18.

[0159] Referring to Figure 26(A), the wireless module 2510 can be coupled to the support member 18. More specifically, the wireless module 2510 can be coupled to the rear surface of the support member 18. Alternatively, the wireless module 2510 can be connected to the support member 18 and the power / communication cable 2630. For example, the communication terminal of the wireless module 2510 and the communication terminal of the support member 18 can be connected by the power / communication cable 2530. One end of the power / communication cable 2630 can be connected to the communication terminal of the wireless module 2510, and the other end can be connected to the communication terminal of the support member 18. However, it is not limited to this, as a separate cable may not be required between the wireless module 2510 and the support member 18 because the communication terminal is formed at the coupling point between the wireless module 2510 and the support member 18. With the coupling of the wireless module 2510 and the radiation detector 10 as shown in Figure 26(A), stable communication and power supply may be possible because the length of the power / communication cable 2630 is short. Furthermore, contact between external materials and the power / communication cable 2630 can be minimized. Also, when the radiation detector 10 and the wireless module 2510 are coupled, there is the advantage of easy portability as no separate installation tools are required. In this case, methods such as Velcro® attachment, shape coupling, and bolting coupling can be used to couple the radiation detector 10 and the wireless module 2510.

[0160] Referring to Figure 26(B), the wireless module 2510 can be coupled to the fixed band 2610. The wireless module 2510 can also be connected to the support member 18 and the power / communication cable 2630. For example, the communication terminal of the wireless module 2510 and the communication terminal of the support member 18 can be connected by the power / communication cable 2530. With the coupling of the wireless module 2510 and the radiation detector 10 as shown in Figure 26(B), the position of the wireless module 2510 can be freely moved within the fixed band 2610, allowing its position to be adjusted to suit the environment. Furthermore, during storage, the wireless module 2510 can be stored together with the fixed band 2610, and the fixed band 2610 can enclose the wireless module 2510 during storage. This reduces the inconvenience of having to carry the fixed band 2610 and the wireless module 2510 separately, resulting in convenient storage.

[0161] Referring to Figure 26(C), the wireless module 2510 can be coupled to a stand 2640 independent of the radiation detector 10. Furthermore, the communication terminals of the wireless module 2510 and the support member 180 can be connected by a power / communication cable 2630. The coupling of the wireless module 2510 and the radiation detector 10 as shown in Figure 26(C) allows for flexible positioning of the wireless module 2510, enabling it to be placed in a location that facilitates smooth communication with external devices. Additionally, the ability to freely determine the position of the wireless module 2510 according to site conditions increases convenience. Moreover, the wireless module 2510 can be positioned to avoid objects that cause communication interference at the site, minimizing communication interference between the external device 2520 and the radiation detector 10.

[0162] As explained above, by using a wireless module depending on the site where the radiation detector is used, the user can maintain a sufficient distance from the imaging position, thereby reducing the user's radiation exposure and allowing the user to evacuate from other hazards present at the site. In addition, communication interference caused by the hardware characteristics of the radiation detector is minimized, and stable communication can be achieved between the radiation detector and external devices through the antenna built into the wireless module.

[0163] Furthermore, power for wired communication can be supplied by the wireless module's battery. Also, since lighter communication cables can be used instead of power cables, problems that may occur during the construction of the inspection environment (such as topographical constraints, communication interference, and cable breakage) can be minimized. Additionally, some of the functions of the radiation detector can be integrated into the wireless module, thereby further reducing the weight of the radiation detector. The wireless module's antenna can be implemented using a variety of antennas, such as an internal patch antenna or an external monopole antenna. Therefore, the wireless module can provide the radiation detector with a communication environment optimized to suit the operating environment.

[0164] Although embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and various modifications by those skilled in the art that utilize the basic concepts of the present invention, as defined in the following claims, also fall within the scope of the present invention.
