Description

[Technical Field]

[0001] The present invention relates to radiation detectors. [Background technology]

[0002] Radiation imaging devices that use radiation such as X-rays and gamma rays to obtain images of the inside of an object are used in various fields such as medicine and industry. A radiation imaging device includes a radiation source that generates radiation and a radiation detector that detects the radiation that has passed through the object.

[0003] Radiation detectors for capturing images of objects such as pipes are commonly called industrial radiation detectors. Industrial radiation detectors must be able to be placed close to objects of various shapes and perform imaging, so they are preferably manufactured in a flexible form. A radiation detector configured for radiography for non-destructive testing of pipes must be able to capture images of both the inner and outer diameters of the pipe and be capable of capturing and reading images of the desired quality depending on the application and imaging environment.

[0028] When the support member of the radiation detector of the present disclosure is unfolded, a space is formed between the end of one side of the front protection part and the fixed bracket frame in the first direction, and the more the support member is bent, the smaller the space between the end of one side of the front protection part and the fixed bracket frame in the first direction becomes.

[0046] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily understand and practice the present invention. However, the present invention may be embodied in many different forms and is not limited to the described embodiments.

[0047] 1 and 2, a 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 in response to incident X-rays. For example, the radiation detector may be a direct conversion radiation detector that directly converts X-ray photons into electrical charges, or an indirect conversion radiation detector that converts X-rays into visible light and then converts the visible light photons into electrical charges. As is well known, a radiation detector may include a TFT array including a plurality of pixel TFT circuits that generate an electrical signal according to the amount of generated electrical charges. The structure and principles for implementing the basic functions of such a radiation detector are widely known in the art to which the present invention pertains, and therefore further detailed description thereof will be omitted.

[0048] As shown in Fig. 2, radiation detector 10 is formed to be bendable, and therefore the components constituting radiation detector 10 are formed of a bendable material or structure. Furthermore, radiation detector 10 according to an embodiment of the present invention can bend in the direction opposite to the bending direction shown in Fig. 2, which means that radiation detector 10 according to an embodiment of the present invention can bend in both directions. For ease of understanding, Fig. 2 shows radiation detector 10 with some components removed.

[0049] 3, the radiation detector 10 includes a detector panel 11. For example, as described above, the detector panel 11 is configured to generate an electrical signal in response to incident X-rays in either a direct or indirect manner. Specifically, if the detector panel 11 is a direct-type radiation detector, the detector panel 11 may include a photoconductor layer that generates charges in response to incident X-rays, and a TFT array including a plurality of pixel TFT circuits that collect the charges generated from the photoconductor layer. On the other hand, if the detector panel 11 is configured as an indirect-type detector, it may include a photodiode layer, a photodiode layer, and a TFT array.

[0050] The detector panel 11 may be formed in a substantially rectangular shape and may include a gate circuit for applying a signal for switching and driving the pixel TFT circuit, and a readout circuit for receiving an output signal from the pixel TFT circuit and outputting it to the outside. For example, the gate circuit and the readout circuit may be disposed on adjacent sides of the detector panel 11.

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

[0052] A front protective panel 13 and a rear protective panel 15 are disposed on either side of the detector panel 11. The front protective panel 13 is disposed on the front side of the detector panel 11, i.e., the side on which the radiation to be detected is incident, and the rear protective panel 15 is disposed on the opposite side. Because radiation, such as X-rays, enters the detector panel 11 through the front protective panel 13, the front protective panel 13 may be formed of a material that is transparent to X-rays. Also, as described above, not only the detector panel 11 but also the front protective panel 13 and rear protective panel 15 may be formed of a flexible material that can bend in both directions. The front protective panel 13 and rear protective panel 15 are disposed adjacent to the front and rear of the detector panel 11 to protect the detector panel 11 and to perform an electrical grounding function. For example, the front protective panel 13 and rear protective panel 15 may be formed of aluminum.

[0053] The radiation detector 10 includes a support member 18 that supports the detector panel 11, the front protective panel 13, and the rear protective panel 15. That is, the detector panel 11, the front protective panel 13, and the rear protective panel 15 are supported by the support member 18 to form a single module. The detector panel 11, the front protective panel 13, and the rear protective 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 protective panel 13, and the rear protective panel 15 are arranged adjacent to each other in a stacked configuration, and therefore undergo different displacements when bending. Therefore, they are configured to bend in both directions while allowing different displacements.

[0054] The support member 18 is also configured to bend in both directions together with the detector panel 11, the front protection panel 13, and the rear protection panel 15. As exemplarily shown in FIG. 3, the support member 18 includes first and second support portions 187, 188 that are spaced apart from each other, and a bendable bending portion 181 that connects the first and second support portions 187, 188. The bending portion 181 includes a plurality of connecting members 182 that are connected in sequence to be able to perform hinge movements relative to each other. The bending portion 181, which is made up of a plurality of connecting members 182 that are able to perform hinge movements, is configured to bend when an external force is applied, as shown in FIG. 2.

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

[0056] The fixed support block 184 is fixedly fastened to the first support portion 187 so as to remain 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 as to be movable in the lateral direction relative to the second support portion 188, i.e., in the Y-axis direction in FIG. 3. One side edge of the detector panel 11, for example, the edge to which the readout circuit 1030 is connected, may be fixed to the fixed support block 184.

[0057] 2 and 7, when the radiation detector 10 bends, the movable support block 183 moves in the direction of the arrow shown in Fig. 7. Accordingly, when the detector panel 11 bends, the movable support block 183 moves and one end of the detector panel 11 can be displaced, thereby enabling the detector panel 11 to stably change shape due to bending.

[0058] A rear cover 19 that closes the space between a first support portion 187 and a second support portion 188 disposed on both sides of the support member 18 may be fixed to the support member 18. As a result, the rear cover 19 covers the rear surface of the rear protection 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 while being disposed in front of the front protection panel 13, and the front protection panel 13 and the rear protection panel 15 are supported by the front cover 17 and the support member 18 while being disposed on both sides of the detector panel 11. At this time, the front protection panel 13 and the rear protection panel 15 are supported by the support member 18 in such a way 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 ring shape similar to the shape of the support member 18 described above. The support member 18 may have a plurality of fastening rods 185 protruding forward from an 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 may 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 sequence along the edges of the first and second support portions 187 and 188 described above and the bending portion 181, as shown in the drawings.

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

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

[0063] In this case, the fastening rod 185 and the fastening slots 131, 151 are configured so that the fastening rod 185 is restricted from moving relative to one another in one direction, but is movable relative to one another in the other direction. For example, the fastening rod 185 and the fastening slots 131, 151 are configured so that the fastening rod 185 is substantially restricted from moving within the fastening slots 131, 151 in the Z-axis direction in FIG. 3, but is movable within the fastening slots 131, 151 in the Y-axis direction. 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. To this end, the fastening slots 131, 151 may have the shape of an elongated hole having a length longer in the Y-axis direction than in the Z-axis direction, and the fastening rod 185 may have a circular cross section having a diameter substantially equal to the length of the fastening slots 131, 151 in the Z-axis direction. The fastening rods 185 fixed to the front cover 17 and the support member 18 are inserted into the elongated fastening slots 131 and 151 of the front protection panel 13 and the rear protection panel 15. Therefore, when the detector panel 11, the front and rear protection panels 13 and 15, the front cover 17, and the support member 18 bend in a direction aligned with the Z axis as shown in Fig. 2, the fastening rods 185 can move along the long fastening direction of the fastening slots 131 and 151, thereby absorbing the difference in displacement between them due to bending, thereby enabling stable bending. Also, the lengths of the fastening slots 131 and 151 may be adjusted to implement a desired bending range.

[0064] Meanwhile, to set reference points 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, movement limiting fastening slots 133 and 153 may be formed at corresponding positions on the front protective panel 13 and the rear protective panel 15. The movement limiting fastening slots 133 and 153 do not have the shape of an elongated hole, but have substantially the same shape as the cross section of the movement limiting fastening rod 186 inserted therein. As a result, the movement limiting fastening rod 186 inserted into the movement limiting fastening slots 133 and 153 is completely blocked from moving in the Z-axis and Y-axis directions. As a result, when the detector panel 11, the front protective panel 13, and the rear protective panel 15 bend, the front protective panel 13 and the rear protective panel 15 are fixed to the support member 18 at the positions of the movement limiting fastening slots 133 and 153. In this respect, it can be said that the movement limiting fastening slots 133 and 153 form reference points for bending of the detector panel 11, the front protective panel 13, and the rear protective panel 15. Although the drawings show exemplary locations of the travel limiting fastener slots 133, 153 and the fastener rods 186 inserted therein, these locations may be varied as required.

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

[0066] 8, the radiation detector 10 according to an embodiment of the present invention may be a direct type digital radiation detector that directly converts X-ray photons into electric charges. Also, the radiation detector 10 according to an embodiment of the present invention may be a bendable flexible radiation detector.

[0067] The radiation detector 10 may include a detector panel 11. FIG. 8 illustrates a cross section of the detector panel 11. Referring to FIG. 8, in the radiation detector panel 11 according to an embodiment of the present invention, a TFT array 813, a charge collector 815, a photoconductor layer 817, and an upper electrode 819 may be sequentially formed on a flexible substrate 811. For example, the substrate 811 may be made of a flexible synthetic resin material, and thus the radiation detector 10 according to the embodiment of the present invention may be embodied 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 while a high voltage from a power source 821 is applied to the upper electrode 819, the photoconductor layer 817 generates charges. The photoconductor layer 817 may be formed of a material that directly converts X-ray photons into charges, i.e., a photoconductor, such as amorphous selenium, lead oxide (PbO), thallium bromide (HgI2), etc. In this case, an electrical insulating layer 818 may be formed between the upper electrode 819 and the photoconductor layer 817, so that the upper electrode 819 and the photoconductor layer 817 are electrically insulated from each other.

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

[0070] When charges are generated in the photoconductive layer 817 due to the incidence of X-rays, positive charges among the generated charges are collected by the charge collector 815. The positive charges collected in the charge collector 815 are then stored in the storage capacitor 8231 of the pixel TFT circuit 823. In this process, the amount of charge generated by the photoconductive layer 817 varies depending on the intensity of the incident X-rays, and as a result, the amount of charge stored in the storage capacitor 8231 varies depending on the intensity of the X-rays. 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 is turned 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-rays detected for each pixel is output, and this output signal can be used to generate an X-ray image. Meanwhile, although not shown in the drawing, as is well known, a circuit element, e.g., a switching element, for initializing the storage capacitor 8231 after outputting an output signal by turning on the TFT switching element 8233 may be connected in parallel to the storage capacitor 8231.

[0071] Meanwhile, referring to Figure 9, a radiation detector 10 according to another embodiment of the present invention may be an indirect-type digital radiation detector that converts X-rays into visible light and then converts the photons of the visible light into electric charges. For example, the radiation detector 10 may include an indirect-type detector panel 11. The same reference numerals are used to designate the same parts as those of the direct-type radiation detector described above with reference to Figure 8, and redundant description will be omitted.

[0072] 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 charges in response to 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 charges. As in the previous embodiment, the charges generated in the photodiode layer 935 are detected by the TFT array 813.

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

[0074] 3 shows an exemplary plan view of the TFT array 813 of the radiation detector 10, which may be configured to have an overall rectangular shape. As described above, the TFT array 813 includes a plurality of pixel TFT circuits 823 arranged in the form of a matrix.

[0075] The gate circuit 1010 is configured to apply a gate signal to a gate line 8235 connected to the pixel TFT circuit 823. According to an embodiment of the present invention, the gate circuit 1010 is divided into two parts, i.e., a gate chip-on-film (gate COF) 1011 and a gate-connecting FPCB (flexible printed circuit board) 1013, and the gate chip-on-film 1011 and the gate-connecting FPCB 1013 are respectively arranged along different sides 1001 and 1002 of the radiation detector panel 11. Here, the sides of the radiation detector panel 11 may be understood as sides of the rectangular region of the TFT array 813. The gate-connecting FPCB 1013 is signal-connected to an external controller through a connector 1014, receives driving signals from the controller, and transmits them to the gate chip-on-film 1011. The gate chip-on-film 1011 generates gate signals according to the received driving signals and applies them to the gate lines 8235.

[0076] The readout circuit 1030 is implemented in a chip-on-film form, and therefore may be referred to as a readout COF. The readout COF 1030 is configured to be connected to an external video signal processor through a connector 1031 so as to transmit an output signal to the video signal processor.

[0077] According to an embodiment of the present invention, the readout COF 1030 may be disposed along one side of the detector panel 11. In this case, the gate chip-on-film 1011 of the gate circuit 1010 may be disposed along one side 1001 of the rectangular detector panel 11, and the gate-connected FPCB 1013 of the gate circuit 1010 and the readout COF 1030 may be disposed along a side 1002 adjacent to the side 1001 of the detector panel 11 on which the gate chip-on-film 1011 is disposed. According to an embodiment of the present invention, in consideration of the fact that the gate-connected FPCB 1013 and the readout COF 1030 must be formed relatively long to be signal-connected to an external controller or video signal processor and must be provided with connectors 1014 and 1031 for connection, the gate-connected FPCB 1013 and the readout COF 1030 are disposed on the same side 1002, thereby significantly reducing the size of the detector panel 11 in the height direction, i.e., the vertical direction in FIG. 10 . As a result, the gate chip-on-film 1011 forms a portion of the detector panel 11 that protrudes outside the TFT array 813 in the height direction, 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 closely in the height direction, and thus imaging can be performed with the radiation detector 10 positioned very close to the connecting portion of the T-shaped pipe. In addition, the gate chip-on-film 1011 and the gate connecting FPCB 1013 are arranged along different sides of the radiation detector, preventing them from interfering with each other.

[0078] Although the direct type radiation detector has been described above as an example, it should be understood that the present invention can also be applied to an indirect type radiation detector having a TFT array. Furthermore, as described above, the radiation detector according to the embodiment of the present invention may be embodied as a bendable flexible detector, or may be a rigid radiation detector having TFTs formed on a glass substrate.

[0079] Figure 11 and Figure 12 are front views of a radiation detector according to an embodiment of the present disclosure.

[0080] In the following, the radiation detector will be described with reference to FIGS.

[0081] The radiation detector 10 of the present 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 some ultraviolet rays. The radiation detector 10 can detect the radiation to obtain a radiation image of the subject. For example, the radiation image obtained by the radiation detector 10 may include at least one of an X-ray image and a CT (Computed Tomography) image.

[0082] The radiation detector 10 may include a detector panel 11. Depending on the method of obtaining an electrical signal, detector panels can be divided into an indirect conversion type that uses a scintillator to obtain an indirect electrical signal from visible light, and a direct conversion type that uses photoconductors to obtain an electrical signal directly from radiation. Depending on the type of element that generates the electrical signal, detector panels can be divided into a CCD type that uses a charge-coupled device, a CMOS type that uses a crystalline silicon CMOS element, and an a-Si type that uses an amorphous silicon TFT (Thin Film Transistor) substrate.

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

[0084] The radiation detector 10 may include at least one of a pixel array, a readout signal unit, a gate driver circuit unit, and a main board. The readout signal unit may be implemented as a plurality of film-type readout ICs (ROICs), and each ROIC may be connected to the main board via a connector.

[0085] The radiation detector 10 may include a light receiving element that detects X-rays and generates an electrical signal, and a readout circuit that reads out the generated electrical signal. The control unit processes the electrical signal output from the readout circuit and generates 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 for the radiation detector 10 to sequentially detect X-ray information and transmit it to an external computer, the radiation detector 10 may use a power and data cable for both power supply and data communication.

[0087] The radiation detector 10 can also use WiFi and Gigabit Ethernet for wired / wireless data transmission, and the control unit of the radiation detector 10 can be connected to communicate with a workstation for variables for driving the image sensor, etc.

[0088] The detector panel 11 may extend in a first direction. In FIG. 11, the first direction may be the left direction. However, the first direction is not limited to this and may be the right direction. The detector panel 11 may detect radiation incident on a first surface. Here, the first surface may refer to the front surface of the detector panel 11. The detector panel 11 may be flexible. That is, the detector panel may be bendable due to its flexibility. If the surface of the object has a round surface, the detector panel 11 may bend and come into close contact with the surface of the object. The sharpness of the radiation image may be increased because the detector panel 11 is positioned in close contact with the surface of the object.

[0089] The radiation detector 10 may include a bending support member 18. Although the rear protection panel 15 and the rear cover 19 are not visible in FIG. 11, at least one of the rear protection panel 15 and the rear cover 19 may be located between the support member 18 and the detector panel 11.

[0090] The support member 18 may be in contact with a second surface of the detector panel 11, which is opposite to the first surface. The second surface may refer to the rear surface of the detector panel 11. The support member 18 may support the detector panel 11. As described above, the detector panel 11 is flexible and therefore bendable. Therefore, without the support member 18, it may be difficult to place the detector panel 11 on an object. This is because the detector panel 11 is easily deformed by the movement of the object or an external force. Therefore, the support member 18 may be configured to support the detector panel 11 so that it maintains a certain shape after bending. The support member 18 may adjust the bending of the detector panel 11 around a bending axis parallel to a second direction intersecting the first direction. In other words, as the support member 18 bends, the detector panel 11 may also bend. Here, the second direction may be an upward direction. However, the second direction is not limited thereto and may be a downward direction.

[0091] The support member 18 may include various components for operation of the radiation detector 10. For example, the support member 18 may include at least one of a control unit, a communication unit, an input unit, and an output unit for operation of the radiation detector 10. Also, as shown in Fig. 12, the detector panel 11 may be embedded in the support member 18. However, the present invention is not limited to this.

[0092] The radiation detector 10 may include a front protection part 1130. The front protection part 1130 may be located in a third direction of the detector panel 11 to protect the detector panel 11. Here, the third direction may refer to the forward direction.

[0093] The front protection part 1130 may 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 protection part 1130 may be fixed to the support member 18. The front protection part 1130 does not have to be fixed to the detector panel 11. Alternatively, only a portion of the front protection part 1130 may be connected to the support member 18. Therefore, flexibility of the front protection part 1130 can be ensured, and the front protection part 1130 only protects the detector panel 11 and can prevent the front protection part 1130 from damaging the support member 18 and the detector panel 11. Details of fixing the front protection part 1130 to the support member 18 will be described later.

[0094] Furthermore, the front protection part 1130 may be formed as a single unit. That is, the front protection part 1130 may have the shape of a single panel, rather than being a combination of various components. For example, the front protection part 1130 may be manufactured by cutting or folding a single plate of a predetermined material. However, the present invention is not limited to this.

[0095] The front protection part 1130 may be flexible. Therefore, the front protection part 1130 may bend due to bending of at least one of the detector panel 11 and the support member 18. In addition, the front protection part 1130 may be detachable from the detector panel 11.

[0096] The detector panel 11 may already be covered with a housing for protecting the detector panel 11. Therefore, the detector panel 11 may also be protected from external impact by the housing. The front protection part 1130 may be an additional means for 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 part 1130 may be configured to be used in addition to the front protection panel 13 and the front cover 17. The front protection part 1130 may be disposed in front of the front cover 17. However, the present invention is not limited thereto, and the front protection part 1130 may replace at least one of the front protection panel 13 and the front cover 17. In other words, the radiation detector may include the front protection part 1130 without including at least one of the front protection panel 13 and the front cover 17.

[0097] In the following, the front protection panel 13 and the front cover 17 will be omitted in order to focus on the front protection part 1130, but 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 part 1130 and the detector panel 11.

[0098] Because the housing for protecting the detector panel 11 is bonded to the detector panel 11, if the material protecting the detector panel 11 becomes defective, 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 detector panel 11 is more likely to be scratched, which may shorten the replacement cycle of the radiation detector 10. The radiation detector 10 of the present disclosure includes a replaceable front protection part 1130, which can contact or approach the object being examined instead of the detector panel 11. Therefore, scratches will likely occur on the front protection part 1130 rather than on the detector panel 11, and the user can easily maintain the radiation detector 10 by simply replacing the front protection part 1130. In other words, the radiation detector 10 of the present disclosure includes a detachable front protection part 1130, which further increases the durability of the radiation detector 10.

[0099] The thickness of the front protective part 1130 may be between 0.1T and 1T. The material of the front protective part 1130 may be a material that transmits radiation. The material of the front protective part 1130 may be a material with a high yield strength, so that it can return to its original shape even when bent by an external force. If the thickness of the front protective part 1130 exceeds 1.0T, the transmittance and yield strength may decrease, making it difficult to use in a bendable radiation detector 10 and reducing the quality of the radiation image. If the thickness of the front protective part 1130 is less than 0.1T, it may not function as a protector and may be less durable. The front protective part 1130 may have a transmittance of 85% or more. If the transmittance of the front protective part 1130 is less than 85%, radiation in a high energy band must be irradiated to obtain a radiation image. Excessive energy exposure may adversely affect the circuit board installed in the detector, and the subject may be exposed to increased radiation. If a front protector 1130 of 1 T or more is used to protect the circuit board from excessive energy exposure, there may be a problem that the front protector 1130 is damaged or does not recover during bending. The yield strength of the front protector 1130 may be 20 MPa or more and 30 MPa or less. For example, the yield strength of the front protector 1130 may be 23 MPa. A front protector 1130 with such physical properties maintains appropriate elasticity during bending and allows repeated bending and flattening without affecting the TFT and circuit board of the radiation detector 10.

[0100] The material of the front protective part 1130 may be at least one of a stainless steel sheet material, a copper sheet material, and a carbon tool steel. However, the material is not limited thereto. The material of the front protective part 1130 may be a composite material sheet made of a mixture of at least one of stainless steel, copper, and carbon tool steel. The carbon tool steel that can be used for the front protective part 1130 may be one of SK1, SK2, SK3, SK4, SK5, SK6, and SK7. To increase the surface hardness of the front protective part 1130, the material may be post-treated. For example, heat treatment, PVD, DLC, etc. may be performed on the material. The front protective part 1130 can maintain its bendability while returning to its original shape by utilizing the above-mentioned material and thickness. Furthermore, since it is permeable to radiation, it has almost no effect on the radiation image. Furthermore, the front protective part 1130 has sufficient strength to protect the detector panel 11. This has been experimentally proven to ensure at least one of optimal bendability, resilience, and radiotransmittance of the front protective part 1130 depending on the material and thickness of the front protective part 1130. Furthermore, even if an external object applies force to the detector, only the front protective part 1130 is damaged, so the same performance as a new detector can be maintained by simply replacing the front protective part 1130, which can be very convenient for users.

[0101] Referring to FIG. 11 , the front protection part 1130 may include an upper fixing part 1131. The upper fixing part 1131 may be formed to protrude upward from the front protection part 1130. The front protection part 1130 may include a lower fixing part 1132. The lower fixing part 1132 may be formed to protrude downward from the front protection part 1130. Holes may be formed in the upper fixing part 1131 and the lower fixing part 1132. The holes formed in the upper fixing part 1131 and the lower fixing part 1132 may be circular holes rather than elongated holes extending laterally. However, this is not limited thereto. The upper fixing part 1131 and the lower fixing part 1132 may be coupled to the support member 18 with screws. That is, screws may be passed through the upper fixing part 1131 and the lower fixing part 1132 to couple to the support member 18.

[0102] The upper fixing part 1131 and the lower fixing part 1132 may be located at the center of the left and right of the front protection part 1130. That is, the distance from the upper fixing part 1131 and the lower fixing part 1132 to the left end of the front protection part 1130 may be the same as the distance from the upper fixing part 1131 and the lower fixing part 1132 to the right end of the front protection part 1130. However, this is not limited to this.

[0103] The upper fixing part 1131 and the lower fixing part 1132 can prevent the front protection part 1130 from moving away from one of the detector panel 11 and the support member 18. In addition, because the upper fixing part 1131 and the lower fixing part 1132 are formed to protrude from the front protection part 1130, deformation of the front protection part 1130 can be minimized. For example, when a force is applied to the front protection part 1130, the force will be applied to the fixed upper fixing part 1131 and lower fixing part 1132. However, since deformation of the upper fixing part 1131 and lower fixing part 1132 has almost no effect on the generation of a radiation image, even if deformation of the upper fixing part 1131 and lower fixing part 1132 occurs, there will be no problem in using the radiation detector 10.

[0104] Furthermore, by minimizing the connection between the front protection part 1130 and the support member 18, damage to the radiation detector 10 caused by the front protection part 1130 can be minimized. As described above, the front protection part 1130 can come into contact with and approach the subject, and therefore can be subjected to a large external force. However, such external force is not transmitted to the detector panel 11 or the support member 18 through the front protection part 1130, so damage to the radiation detector 10 can be minimized.

[0105] Furthermore, since the front protection part 1130 is tightly attached to the detector panel 11 by the upper fixing part 1131 and the lower fixing part 1132 , the image of the radiation detector 10 is not distorted by the front protection part 1130 .

[0106] 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 located in a third direction of at least one of the support member 18 and the front protection part 1130. The third direction may refer to the front side. 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] Fig. 13 is a diagram illustrating a fixing bracket according to an embodiment of the present disclosure, and Fig. 14 is a diagram illustrating a fixing bracket according to an embodiment of the present disclosure.

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

[0109] 13 and 14, the fixing bracket 1210 may include a protective cover 1310. The protective cover 1310 may cover at least a portion of one side of the front protective part 1130. For example, the protective cover 1310 may cover at least a portion of the left side of the front protective part 1130. Also, the protective cover 1310 may cover at least a portion of the right side of the front protective part 1130. Referring to FIG. 14, the front protective part 1130 may be located between the protective cover 1310 and the support member 18. Although FIG. 13 shows the fixing bracket 1210 divided by a dotted line, this is for illustrative purposes only, and the actual fixing bracket 1210 does not have the dotted line.

[0110] 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, the first direction is not limited thereto and may be the right side. The fixing bracket frame 1320 may be located on the left side of the protective cover 1310 of the left fixing bracket 1210. The fixing bracket frame 1320 may be located on the right side of the protective cover 1310 of the right fixing bracket 1210. The fixing bracket frame 1320 may be in surface contact with the support member 18 to prevent the fixing bracket 1210 from shaking on the support member 18.

[0111] 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. The fixing bracket fixing portion 1330 may be connected to the fixing bracket frame 1320 in a direction opposite to the second direction, which may be an upward direction. However, this is not limited to this, and the second direction may also be a downward direction. 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 connected to the support member 18 with screws.

[0112] Referring to FIG. 14 , one side of the protector cover 1310 may be recessed in a third direction relative to one side of the fixing bracket frame 1320. The third direction may refer to the front. The reason one side of the protector cover 1310 is recessed in the third direction relative to one side of the fixing bracket frame 1320 may be to provide a space for the protector cover 1310 to accommodate the front protector 1130. A height 1410 between one side of the protector cover 1310 and one side of the fixing bracket frame 1320 may be greater than or equal to the thickness of the front protector 1130. By covering at least a portion of the front protector 1130 in this manner, the protector cover 1310 can help the front protector 1130 to bend and return to its original state without any problems. The protector cover 1310 can also help maintain a constant distance between the front protector 1130 and the detector panel 11. That is, the left and right sides of the front protector 1130 can be prevented from moving away from the detector panel 11.

[0113] 13 and 14, when the support member 18 is unfolded, 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 refer to the left side. Also, unlike FIGS. 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, this is not limited thereto, and 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 expanded in this manner, a space 1420 is formed between the end of one side of the front protection part 1130 in the first direction and the fixed bracket frame 1320, so that even if the support member 18 is bent, the protection part cover 1310 can cover the front protection part 1130 without any problems.

[0114] FIG. 15 is a diagram illustrating a front protection part according to an embodiment of the present disclosure.

[0115] 11 to 14 illustrate an embodiment in which the fixing portions included in the front protection portion 1130 are located at the center of the left and right sides. However, this is not limiting. As shown in FIG. 15, the fixing portions of the front protection portion 1130 may be located at positions other than the center of the left and right sides of the front protection portion 1130. For example, the front protection portion 1130 may include upper fixing portions 1510, 1520, 1530, and 1540. The front protection portion 1130 may also include lower fixing portions 1550, 1560, 1570, and 1580.

[0116] FIG. 15 illustrates the front protection unit 1130 including four upper fixing portions 1510, 1520, 1530, and 1540 on the upper side and four lower fixing portions 1550, 1560, 1570, and 1580 on the lower side. However, this is not limited to this. There may be two or more upper fixing portions. Also, there may be two or more lower fixing portions. Furthermore, the upper fixing portions 1510, 1520, 1530, and 1540 and the lower fixing portions 1550, 1560, 1570, and 1580 may include elongated slots on the left and right sides instead of circular holes. However, this is not limited to this. When multiple upper fixing portions and multiple lower fixing portions are included in this manner, the front protection unit 1130 can be firmly fixed to the support member 18. Therefore, the front protection unit 1130 can be prevented from shaking relative to the support member 18. Furthermore, the distance between the front protection unit 1130 and the detector panel 11 can be maintained constant. Therefore, the image of the radiation detector 10 does not become distorted by the front protection part 1130 .

[0117] FIG. 16 is a diagram illustrating a front protection part according to an embodiment of the present disclosure.

[0118] The front protection part 1130 may include left fixing parts 1610, 1620 and right fixing parts 1630, 1640. At least one left fixing part 1610, 1620 may be formed protruding leftward on the left side of the front protection part 1130. At least one right fixing part 1630, 1640 may be formed protruding rightward on the right side of the front protection part 1130. The right fixing parts 1630, 1640 and the left fixing parts 1610, 1620 may be screwed to the support member 18. The left fixing parts 1610, 1620 and the right fixing parts 1630, 1640 may have elongated holes extending laterally.

[0119] When the front protection part 1130 includes the left fixing parts 1610, 1620 and the right fixing parts 1630, 1640 as described above, the front protection part 1130 can be firmly fixed to the support member 18. Therefore, the front protection part 1130 can be prevented from shaking relative to the support member 18. In addition, the distance between the front protection part 1130 and the detector panel 11 can be maintained constant. Therefore, the image of the radiation detector 10 can be prevented from being distorted by the front protection part 1130. In addition, the right fixing parts 1630, 1640 and the left fixing parts 1610, 1620 can prevent the front protection part 1130 from being deformed.

[0120] 15, the front protection part 1130 includes upper fixing parts 1510, 1520, 1530, and 1540 and lower fixing parts 1550, 1560, 1570, and 1580. Also, in FIG. 16, the front protection part 1130 includes left fixing parts 1610 and 1620 and right fixing parts 1630 and 1640. In combination, the front protection part 1130 may include upper fixing parts 1510, 1520, 1530, and 1540, lower fixing parts 1550, 1560, 1570, and 1580, left fixing parts 1610 and 1620, and right fixing parts 1630 and 1640. When the front protection part 1130 includes 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 in this manner, the front protection part 1130 can be firmly fixed to the support member 18. Therefore, the front protection part 1130 can be prevented from shaking relative to the support member 18.

[0121] FIG. 17 is a diagram illustrating a front protection part according to an embodiment of the present disclosure.

[0122] 17, similar to FIG. 16, the front protection part 1130 can include left fixing parts 1610 and 1620 and right fixing parts 1630 and 1640. In addition, the front protection part 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 part 1130 from floating away from the detector panel 11 and the support member 18.

[0123] The upper bracket 1710 and the lower bracket 1720 may extend upward and downward. One side of the upper bracket 1710 may be screwed to the support member 18, and the other side may contact the front protection part 1130. Therefore, the upper side of the front protection part 1130 may be fixed by the upper bracket 1710. The other side of the lower bracket 1720 may be screwed to the support member 18, and one side may contact the front protection part 1130. Therefore, the lower side of the front protection part 1130 may be fixed by the lower bracket 1720. Unlike FIG. 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 between the upper bracket 1710 and the lower bracket 1720. Therefore, the front protection part 1130 can move slightly relative to the support member 18, which prevents the front protection part 1130 from being deformed during suspension. Furthermore, the front protection part 1130 can be removed from the support member 18 by rotating the upper bracket 1710 and the lower bracket 1720 about an axis extending in the front-rear direction, which may improve assembly efficiency of the front protection part 1130. Furthermore, the front protection part 1130 can be removed from the support member 18 by moving it to the left or right while the upper bracket 1710 and the lower bracket 1720 remain stationary, which may improve assembly efficiency of the front protection part 1130.

[0124] FIG. 18 is a diagram illustrating a front protection part according to an embodiment of the present disclosure.

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

[0126] The fixing brackets 1810, 1820 may cover at least a portion of one side of the front protection part 1130. For example, the upper fixing bracket 1810 may cover at least a portion of the upper side of the front protection part 1130. Furthermore, the lower fixing bracket 1820 may cover at least a portion of the lower side of the front protection part 1130. The fixing brackets 1810, 1820 may be fixed to the support member 18. For example, the fixing brackets 1810, 1820 may be screwed to the support member 18.

[0127] The upper fixing bracket 1810 may include upper separation prevention portions 1811, 1812, and 1813 that protrude downward and prevent the front protection portion 1130 from separating. Although FIG. 18 illustrates three upper separation prevention portions 1811, 1812, and 1813, the present invention is not limited to this and the number of upper separation prevention portions may be two or more. The left-to-right lengths of the upper separation prevention portions 1811, 1812, and 1813 may become shorter toward the center of the front protection portion 1130 and longer toward the left or right side of the front protection portion 1130. For example, the left-to-right length of the upper separation prevention portion 1812 located in the center may be shorter than the left-to-right lengths of the upper separation prevention portion 1811 located on the left and the upper separation prevention portion 1813 located on the right. As described above, the left and right lengths of the upper separation prevention parts 1811, 1812, and 1813 become shorter toward the center of the front protection part 1130, which may reduce deformation of the front protection part 1130. In addition, by increasing the flexibility of the front protection part 1130, the surface of the radiation detector 10 may be able to closely approach the surface of a round object.

[0128] The lower fixing bracket 1820 may include lower separation prevention portions 1821, 1822, and 1823 that protrude upward and prevent separation of the front protection portion 1130. Although FIG. 18 illustrates three lower separation prevention portions 1821, 1822, and 1823, the present invention is not limited to this and the number of lower separation prevention portions may be two or more. The left-to-right lengths of the lower separation prevention portions 1821, 1822, and 1823 may become shorter toward the center of the front protection portion 1130 and longer toward the left or right side of the front protection portion 1130. For example, the left-to-right length of the lower separation prevention portion 1822 located in the center may be shorter than the left-to-right lengths of the lower separation prevention portion 1821 located on the left and the lower separation prevention portion 1823 located on the right. As described above, the left and right lengths of the lower separation prevention parts 1821, 1822, and 1823 become shorter toward the center of the front protection part 1130, which reduces deformation of the front protection part 1130. In addition, by increasing the flexibility of the front protection part 1130, the surface of the radiation detector 10 can closely approach the surface of a round object.

[0129] FIG. 19 may be a diagram for explaining the connection between the support member 18 and the front protection part according to an embodiment of the present disclosure.

[0130] 19 , an upper fixing bracket 1810 and a lower fixing bracket 1820 may be coupled to the support member 18. The front protection part 1130 may be coupled 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 separation prevention parts 1811, 1812, 1813 and the lower separation prevention parts 1821, 1822, 1823 come into contact with the front protection part 1130 to fix the front protection part 1130 to the support member 18. The rear surfaces of the upper separation prevention parts 1811, 1812, 1813 and the lower separation prevention parts 1821, 1822, 1823 that come into contact with the front protection part 1130 may include an elastic material. For example, the elastic material may include at least one of rubber, urethane, and silicone. The upper separation prevention parts 1811, 1812, 1813 and the lower separation prevention parts 1821, 1822, 1823 come into contact with the front protection part 1130 to prevent the front protection part 1130 from separating from the support member 18 due to friction. However, the present invention is not limited to this, and the upper separation prevention portions 1811 , 1812 , 1813 and the lower separation prevention portions 1821 , 1822 , 1823 do not have to come into contact with the front protection portion 1130 .

[0132] According to the radiation detector 10 of FIG. 19, the user can fix the front protection part 1130 to the support member 18 simply by sliding the front protection part 1130 along the upper fixing bracket 1810 and the lower fixing bracket 1820 of the support member 18, which can increase convenience.

[0133] FIG. 20 is a diagram illustrating a further example of a front protection part according to an embodiment of the present disclosure.

[0134] Figure 20 may show a front protection part 1130 that combines Figures 15 and 16. Referring to Figures 15, 16, and 20, the front protection part 1130 may include upper fixing parts 1510, 1520, 1530, and 1540. The front protection part 1130 may also include lower fixing parts 1550, 1560, 1570, and 1580. The front protection part 1130 may also include left fixing parts 1610 and 1620 and right fixing parts 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 may be screw-coupled 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 may have elongated holes in the left-right direction. Therefore, the front protection part 1130 may be coupled to the support member 18 so as to be movable left and right. Because the front protection part 1130 is movable left and right with respect to the support member 18, the front protection part 1130 may not be deformed even if the front protection part 1130 is repeatedly bent and unfolded. In addition, the front protection part 1130 can be firmly connected to the support member 18 by upper fixing parts 1510, 1520, 1530, 1540, lower fixing parts 1550, 1560, 1570, 1580, left fixing parts 1610, 1620 and right fixing parts 1630, 1640.

[0136] FIG. 21 may be a diagram for explaining a screw connection according to one embodiment of the present disclosure.

[0137] As described above, the front protection part 1130 can be screwed to the support member 18. That is, a screw can be passed through a hole in the front protection part 1130 and connected to the support member 18.

[0138] 21A, at least one of the upper fixing portions 1510, 1520, 1530, 1540, the lower fixing portions 1550, 1560, 1570, 1580, the left fixing portions 1610, 1620, and the right fixing portions 1630, 1640 may have a slot that is long in the left-right direction. Therefore, even when the screw 2110 is engaged, the front protection portion 1130 can move left and right relative to the support member 18. Because the front protection portion 1130 can move left and right relative to the support member 18, the front protection portion 1130 can prevent strain from being applied to the detector panel 11 and the support member 18 when the support member 18 is bent. This can increase the durability of the radiation detector 10.

[0139] 21(B), at least one of the upper fixing portions 1510, 1520, 1530, 1540, the lower fixing portions 1550, 1560, 1570, 1580, the left fixing portions 1610, 1620, and the right fixing portions 1630, 1640 may 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 refer to the portion where a thread is formed. The diameter of the circular hole may be 1.5 to 2 times larger than the diameter of the screw 2120. Therefore, the front protection portion 1130 can move left and right and up and down relative to the support member 18. Because the front protection portion 1130 can move left and right and up and down relative to the support member 18, the front protection portion 1130 can prevent strain on the detector panel 11 and the support member 18 when the support member 18 is bent. As shown in (B) of Figure 21, the diameter of the screw head may be larger than the diameter of the circular hole of at least one of the upper fixing portions 1510, 1520, 1530, 1540, the lower fixing portions 1550, 1560, 1570, 1580, the left fixing portions 1610, 1620 and the right fixing portions 1630, 1640.

[0140] Fig. 22 is a diagram illustrating a front protection part according to an embodiment of the present disclosure. Fig. 23 is a diagram illustrating a front protection part according to an embodiment of the present disclosure.

[0141] The front protection part 1130 may include a magnetic coupling part. The magnetic coupling part may be located on the front or rear surface of the front protection part 1130. The magnetic coupling part may be located on at least a portion of the four sides of the front protection part 1130. The magnetic coupling part 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. Thus, the front protection portion 1130 can be coupled to the support member 18. When using the magnetic coupling portion in this manner, the front protection portion 1130 and the support member 18 can be coupled to each other simply by placing the front protection portion 1130 on the support member 18, which can greatly facilitate assembly of the front protection portion 1130 and the support member 18. Furthermore, by roughly aligning the positions of the front protection portion 1130 and the support member 18, the front protection portion 1130 is coupled to the support member 18 in a specific direction and position by magnetic force, which can improve user convenience. Furthermore, the polarity of the magnet may be used to couple the front protection portion 1130 to the support member 18 only when the front protection portion 1130 is positioned in a specific direction.

[0143] 22A shows the magnetic coupling part 2210. The magnetic coupling part 2210 may include at least one of a left magnetic coupling part 2211, an upper magnetic coupling part 2212, a right magnetic coupling part 2213, and a lower magnetic coupling part 2214. The magnetic coupling part 2210 may be attached to the rear surface of the front protection part 1130. The front protection part 1130 may be coupled to the support member 18 by the magnetic force between the magnetic coupling part 2210 and the support member 18.

[0144] 22B, a user may place the front protection part 1130 on the support member 18. The front protection part 1130 may be movable in front of the support member 18. At this time, the magnetic coupling part 2210 may be positioned in front of the front protection part 1130. The magnetic coupling part 2210 may be coupled to the support member 18 by magnetic force. The front protection part 1130 between the magnetic coupling part 2210 and the support member 18 may be fixed to the support member 18 by friction.

[0145] 23A shows a magnetic coupling part 2310. The magnetic coupling part 2310 may be attached to the rear surface of the front protection part 1130. The front protection part 1130 may be coupled to the support member 18 by the magnetic force between the magnetic coupling part 2310 and the support member 18.

[0146] However, the present invention is not limited thereto, and the magnetic coupling part 2310 does not have to be adhered to the front protection part 1130. The magnetic coupling part 2310 may have a magnet or a magnetic metal material. The magnetic coupling part 2310 may be formed along the four sides of the front protection part. The magnetic coupling part 2310 may have a shape with a hole 2320 drilled in the center. Referring to FIG. 23B, the magnetic coupling part 2310 may be positioned in the third direction of the front protection part 1130. The third direction may refer to the front side. The magnetic coupling part 2310 may couple with the magnet or magnetic metal material of the support member 18 to couple the front protection part 1130 to the support member 18. The front protection part 1130 between the magnetic coupling part 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 detects a magnetic field. The sensor unit may be located on the support member 18. The control unit may detect whether the magnetic coupling units 2210, 2310 are coupled to the support member 18 based on a signal from the sensor unit. That is, the control unit may determine that the magnetic coupling units 2210, 2310 are coupled to the support member 18 when the sensor unit detects a magnetic flux equal to or greater than a critical magnetic flux. The control unit may determine that the magnetic coupling units 2210, 2310 are coupled to the support member 18 when the sensor unit detects a magnetic force equal to or greater than a critical magnetic force. The control unit may determine that the magnetic coupling units 2210, 2310 are not coupled to the support member 18 when the sensor unit detects a magnetic flux less than the critical magnetic flux. The control unit may determine that the magnetic coupling units 2210, 2310 are not coupled to the support member 18 when the sensor unit detects a magnetic force less than the critical magnetic flux. The fact that the magnetic coupling units 2210 and 2310 are coupled to the support member 18 may mean that the front protection unit 1130 is coupled to the support member 18. The support member 18 may include a plurality of sensors. The control unit can determine that the magnetic coupling units 2210 and 2310 are coupled to the support member 18 only if all of the magnetic fluxes measured by the plurality of sensors are equal to or greater than the critical magnetic flux.

[0148] FIG. 24 is a diagram illustrating a front protection part according to an embodiment of the present disclosure.

[0149] 24A, the front protection part 1130 may include front protection part connectors 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 part connectors 2411 and 2412 located on the upper left and upper right sides may extend upward from the front protection part 1130. In addition, the front protection part connectors 2413 and 2414 located on the lower left and lower right sides may extend downward from the front protection part 1130.

[0150] 24A, the front protector 1130 may include front protector fixing portions 2421, 2422, 2423, and 2424. The front protector fixing portions 2421, 2422, 2423, and 2424 may be connected to the front protector connecting portions 2411, 2412, 2413, and 2414. The front protector fixing portions 2421, 2422, 2423, and 2424 may be configured to connect the front protector 1130 to the support member 18. In addition, the front protector fixing portions 2421, 2422, 2423, and 2424 may have surfaces perpendicular to the front protector. The upper left front protector fixing portion 2421 may be screwed to the left side of the upper surface of the support member 18. The upper right front protector fixing portion 2422 may be screwed to the right side of the upper surface of the support member 18. The left lower front protector fixing portion 2423 may be screwed to the left side of the lower surface of the support member 18. The right lower front protector fixing portion (2SS424) may be screwed to the right side of the lower surface of the support member 18. At least one elongated hole extending left and right may be formed in the front protector fixing portions 2421, 2422, 2423, and 2424. The elongated hole allows the front protector 1130 to move left and right relative to the support member 18, so that the front protector 1130 does not impose a burden on the detector panel 11 and the support member 18 when the support member 18 is bent. This may increase the durability of the radiation detector 10.

[0151] When a radiation detector is used outdoors, wireless communication may be required. In this case, a detector that does not include a communication module only communicates 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, a problem may arise in that the reliability of data transmission through the cable decreases. Therefore, a wireless module that supports wireless communication may be connected to a wired radiation detector. Hereinafter, a wireless module according to an embodiment of the present disclosure will be described with reference to FIGS. 25 and 26.

[0152] FIG. 25 is a block diagram illustrating a wireless module according to an 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 the support member 18. For example, the wireless module 2510 may be connected to the support member 18 via 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 as different lines, but are not limited to this, and the same line may serve as both the power cable and the communication cable. For example, the communication cable may also serve as the power cable. Since a power cable is generally thick, the communication cable can be responsible for both power supply and communication, thereby 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 a power supply unit and can supply electrical energy to the radiation detector 10 through the power cable. However, this is not limiting, and the radiation detector 10 may supply electrical energy to the wireless module 2510 through the power cable.

[0155] The wireless module 2510 can supply electrical energy used for communication by the radiation detector 10. Therefore, it is possible to eliminate the need to connect an additional power supply to the radiation detector 10 for communication.

[0156] The wireless module 2510 may also support wireless communication with the external device 2520. More specifically, the radiation detector 10 may communicate with the wireless module 2510 via a communication cable. The radiation detector 10 may transmit data to the external device 2520 using the wireless module 2510. For example, the radiation detector 10 may transmit data to the wireless module 2510, and the wireless module 2510 may then wirelessly communicate with the external device 2520. The data transmitted from the radiation detector 10 to the wireless module 2510 may be data related to an image. The external device 2520 may receive the data and display the image. The external device 2520 may include at least one of an external controller and an external computer. The external computer may be embodied as at least one of a PC, a tablet, and a smartphone. The radiation detector 10 may also receive data from the external device 2520 using the wireless module 2510. For example, the wireless module 2510 may 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 through a communication cable. The data received from the external device 2520 can be a command signal for controlling the radiation detector 10.

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

[0158] 26, the radiation detector 10 may include a fixing band 2610. The fixing band 2610 may 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. Therefore, the radiation detector 10 may capture an image of the object 2620 while being movably fixed to the object 2620. The fixing band 2610 may include an elastic material. Also, a coupling portion for coupling to the support member 18 may be formed on one side and the other side of the fixing band 2610.

[0159] 26(A), the wireless module 2510 may be coupled to the support member 18. More specifically, the wireless module 2510 may be coupled to the rear surface of the support member 18. The wireless module 2510 may also be connected to the support member 18 via a power / communication cable 2630. For example, the communication terminal of the wireless module 2510 and the communication terminal of the support member 18 may be connected via the power / communication cable 2630. One side of the power / communication cable 2630 may be connected to the communication terminal of the wireless module 2510, and the other side of the power / communication cable 2630 may be connected to the communication terminal of the support member 18. However, this is not limited thereto, and since the communication terminal is formed at the coupling portion of the wireless module 2510 and the support member 18, a separate cable may not be used between the wireless module 2510 and the support member 18. When the wireless module 2510 and the radiation detector 10 are coupled as shown in FIG. 26(A), the length of the power / communication cable 2630 is short, which may enable stable communication and power supply. In addition, contact of external objects with the power / communication cable 2630 can be minimized. Furthermore, when the radiation detector 10 and the wireless module 2510 are combined, there is an advantage that no separate installation tool is required, making it easy to carry. In this case, methods for combining the radiation detector 10 and the wireless module 2510 may include Velcro® attachment, shape coupling, bolting coupling, etc.

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

[0161] 26(C), the wireless module 2510 may be coupled to a mounting base 2640 independent of the radiation detector 10. Furthermore, the communication terminal of the wireless module 2510 and the communication terminal of the support member 180 may be connected by a power / communication cable 2630. By coupling the wireless module 2510 and the radiation detector 10 as shown in FIG. 26(C), the wireless module 2510 can be freely positioned, so that the wireless module 2510 can be positioned where communication with an external device is smooth. Furthermore, the position of the wireless module 2510 can be freely determined depending on the on-site conditions, which increases convenience. Furthermore, the wireless module 2510 can be positioned to avoid objects that cause communication interference on-site, so that communication interference between the external device 2520 and the radiation detector 10 can be minimized.

[0162] As described above, by using a wireless module depending on the site where the radiation detector is used, the user can be kept a sufficient distance from the imaging position, thereby reducing radiation exposure to the user and enabling the user to escape from other hazards present at the site. In addition, communication interference due to the hardware characteristics of the radiation detector is minimized, and the radiation detector and external device can communicate stably through the antenna built into the wireless module.

[0163] In addition, power for wired communication can be supplied by the battery of the wireless module. Furthermore, since a communication cable, which is lighter than a power cable, can be used, problems that may occur during the construction of an inspection environment (such as topographical constraints, communication interference, and cable breakage) can be minimized. Furthermore, some of the functions built into the radiation detector can be separated by being built into the wireless module, thereby further reducing the weight of the radiation detector. The antenna of the wireless module can be implemented with various antennas, such as a built-in patch antenna or an external monopole antenna. Therefore, the wireless module can provide the radiation detector with a communication environment optimized for the usage environment.

[0164] Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these examples, and various modifications made by those skilled in the art using the basic concept of the present invention defined in the following claims also fall within the scope of the present invention.
