Description

Bendable radiation detectors provide improved radiation imaging

[0001] The present invention relates to a bendable radiation detector that provides improved radiation images. More specifically, the radiation detector provides improved radiation images by minimizing noise in signals generated within the radiation detector.

[0002] Bendable radiation detectors are a relatively recent development in the field of radiology imaging. While the idea of ​​bendable radiation detectors has existed for decades, recent advances in materials science and engineering have led to the full-scale research and development of radiation detectors that are both flexible and waterproof.

[0003] Researchers and developers have recently focused on developing radiation detectors. Conventional bendable radiation detectors may be less sensitive to radiation than standard radiation detectors. This is because bendable radiation detectors utilize thinner, more flexible materials, which may be less sensitive to radiation than those used in standard flat radiation detectors.

[0004] Additionally, conventional bendable radiation detectors often exhibit more image distortion than standard radiation detectors. This is because the various bending structures and the potential for short circuits make it difficult to secure sufficient ground.

[0005] Additionally, bendable radiation detectors have complex electronic circuits and various hardware structures to provide bending, which increases the difficulty of manufacturing.

[0006] For the above reasons, it has been very difficult to develop a bendable radiation detector that can be used in harsh environments by applying waterproof functions.

[0007] The present disclosure relates to a bendable radiation detector that provides improved radiation images. The radiation detector can prevent external substances from penetrating into the interior of the radiation detector while providing improved radiation images.

[0046] Below, with reference to the attached drawings, a detailed description of the embodiments is provided so that those skilled in the art can easily implement the present disclosure. Furthermore, in order to clearly illustrate the present disclosure, portions irrelevant to the description are omitted from the drawings.

[0047] FIG. 1 is a drawing illustrating a radiation detector according to one embodiment of the present disclosure. FIG. 2 is a drawing illustrating a radiation detector according to one embodiment of the present disclosure.

[0048] Hereinafter, a radiation detector will be described with reference to FIGS. 1 and 2. FIG. 1 is a drawing in which the control board (210) and the control board bracket (220) are omitted for convenience of explanation. FIG. 2 is a drawing in which the rear elastic jacket (124) and the side elastic jacket (125) are omitted for convenience of explanation.

[0049] The radiation detector (100) of the present disclosure may be a bendable device that detects radiation and has a waterproof structure. First, the radiation detector (100) may detect 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 (100) may detect radiation to obtain a radiation image of the subject. For example, the radiation image obtained by the radiation detector (100) may include at least one of an X-ray image and a CT (Computed Tomography) image. The radiation detector (100) of the present disclosure may include a bending support member (120) to provide a waterproof function and may be bendable. The bending support member (120) will be described in detail later.

[0050] The radiation detector (100) may include a radiation detection panel (110). The radiation detection panel can be divided into an indirect conversion type that obtains an indirect electric signal by visible light using a scintillator and a direct conversion type that obtains an electric signal directly from radiation using photoconductors, depending on the method of obtaining an electric signal, and can be divided into a CCD method that uses a charge-coupled device, a CMOS method that uses a CMOS device of crystalline silicon, and an a-Si method that uses a TFT (Thin Film Transistor) substrate of amorphous silicon, depending on the type of device that generates the electric signal.

[0051] A radiation detector (100) including a radiation detection panel (110) is equipped with various sensors and can implement digital image data with the electric signals and position information of the sensors proportional to the amount of incident radiation. The radiation detector (100) can obtain shooting results close to real-time, secure high resolution and a wide dynamic range with relatively little radiation, and due to the nature of digital data, storage and processing of the shooting results are easy. The radiation detector (100) includes a read-out signal unit that reads an electrical signal output from a pixel array, and a gate driver that turns on a switching element so that the read-out signal unit can read the electrical signal, and the electrical signal detected by the read-out signal unit is converted into an image signal through a certain processing process in a controller equipped on a main board and then transmitted to a display device for displaying an X-ray image.

[0052] The radiation detection panel (110) can extend in a first direction. The first direction can be the left direction. However, it is not limited thereto and can also be the right direction. The radiation detection panel (110) can detect radiation incident on a first surface. Here, the first surface can refer to the front surface (front surface) of the radiation detection panel (110). The radiation detection panel (110) can be flexible. That is, the radiation detection panel can be flexible and bendable. When the surface of the subject has a round surface, the radiation detection panel (110) can be bent and adhered to the surface of the subject. Since the radiation detection panel (110) is positioned in adherence to the surface of the subject, the sharpness of the radiation image can be improved.

[0053] The radiation detector (100) may include a bending support member (120). The bending support member (120) may be in contact with at least one of a first surface of the radiation detection panel (110), a second surface opposite to the first surface, and a third surface excluding the first and second surfaces. The second surface may refer to the rear surface of the radiation detection panel (110). The third surface may refer to a side surface of the radiation detection panel. For example, the third surface may include at least one of an upper surface, a left surface, a right surface, and a lower surface.

[0054] The bending support member (120) may be configured to protect the radiation detection panel (110). Since the radiation detection panel (110) is a sensitive component, it can be easily damaged by external impact, and the quality of the radiation image may deteriorate due to external stimuli. In addition, if an external substance enters the radiation detection panel (110), the quality of the radiation image may deteriorate, or the components included in the radiation detector (100) may be damaged. The bending support member (120) can prevent the circuits included in the radiation detection panel (110) and the radiation detector (100) from being damaged by external impact, alleviate the external impact, and prevent external substances from entering the interior of the radiation detector (100).

[0055] In addition, the bending support member (120) can support the radiation detection panel (110). As described above, the radiation detection panel (110) is flexible and can be bent. Therefore, if there is no bending support member (120), it may be difficult to keep the radiation detection panel (110) still with respect to the subject. This is because the radiation detection panel (110) will be easily deformed by the movement of the subject or an external force. Therefore, the bending support member (120) may be configured to support the radiation detection panel (110) so that it maintains a certain shape after being bent. The bending support member (120) can adjust the bending of the radiation detection panel (110) around a bending axis that is parallel to a second direction that intersects the first direction. In other words, the radiation detection panel (110) can also be bent as much as the bending support member (120) is bent. Here, the second direction may be an upward direction. However, it is not limited to this, and the second direction can be downward.

[0056] The bending support (120) may include various configurations for the operation of the radiation detector (100). For example, the bending support (120) may 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 (100). For example, the bending support (120) may include a control board (210), and the control board (210) may include at least one of a control unit, a communication unit, an input unit, and an output unit. The control board is illustrated in FIG. 2. In addition, as illustrated in FIGS. 1 and 2, the radiation detection panel (110) may be embedded in the bending support (120). However, the present invention is not limited thereto.

[0057] The bending support member (120) may include at least one of a main plate (121), a conductive gasket (122), a front plate (123), a rear elastic jacket (124), and a side elastic jacket (125).

[0058] Below, the configuration included in the bending support member (120) is described in detail.

[0059] FIG. 3 is a drawing showing a part of a bending support member (120) according to one embodiment of the present disclosure.

[0060] The radiation detector (100) may include a main plate (121). The main plate (121) may support the radiation detection panel (110). In addition, the main plate (121) may be plate-shaped. Therefore, the flexible radiation detection panel (110) may maintain the shape of a plate. Since the main plate (121) is also flexible, the main plate (121) may be bent together with the radiation detection panel (110). Although the main plate (121) is plate-shaped, a through hole (320) may be formed in at least a portion thereof to allow a cable for connecting the radiation detection panel (110) and the control board (210) to pass therethrough.

[0061] The material of the main plate (121) may be a composite material sheet mixed with at least one of carbon, stainless steel, copper, and carbon tool steel. The carbon tool steel that can be used as the main plate (121) may be one of SK1, SK2, SK3, SK4, SK5, SK6, and SK7. In order to increase the surface hardness of the main plate (121), a post-processing may be performed on the material. For example, heat treatment, PVD, DLC, etc. may be performed on the material. The main plate (121) can maintain bendability and return to its original state by using the above materials.

[0062] In addition, the main plate (121) may be conductive. In addition, the main plate (121) may be electrically connected to the control board (210). More specifically, the main plate (121) may be electrically connected to the ground of the control board (210) to compensate for the insufficient ground area of ​​the control board (210). The ground area of ​​the main plate (121) may significantly reduce noise in the radiographic image.

[0063] The main plate (121) may be located on the opposite side of the third direction of the radiation detection panel (110). The third direction may mean the front. That is, the opposite side of the radiation detection panel (110) on the third direction may mean the rear side of the radiation detection panel (110). That is, the radiation detection panel (110) may be located on the front side of the main plate (121).

[0064] At least a portion of the radiation detection panel (110) may be adhered to at least a portion of the front surface of the main plate (121). The adhesive surface (310) may be positioned in an area of ​​the front surface of the main plate (121) that is oriented opposite to the first direction. However, the present invention is not limited thereto, and the adhesive surface (310) may be positioned in an area of ​​the front surface of the main plate (121) that is oriented toward the first direction. In addition, the adhesive surface (310) may be positioned in at least one of an area of ​​the front surface of the main plate (121) that is oriented toward the second direction or an area of ​​the front surface of the main plate (121) that is oriented toward the opposite direction to the second direction.

[0065] The adhesive surface (310) of the main plate (121) can be bonded to at least a portion of the back surface of the radiation detection panel (110) using an adhesive. The adhesive may be a double-sided tape, a bond, a belt, or silicone. According to various embodiments of the present disclosure, a hardware-type bonding structure is formed on the adhesive surface (310), so that the adhesive surface can be hardware-type bonded to the radiation detection panel (110). Since the adhesive surface (310) is located in an area of ​​the main plate (121) that is inclined toward the first direction or an area that is inclined opposite to the first direction, one side of the main plate (121) can be bonded to one side of the radiation detection panel (110). That is, one side of the radiation detection panel (110) can be fixed to the main plate (121). In addition, since the other side of the radiation detection panel (110) is not coupled with the main plate (121), when the radiation detector (100) is bent, the other side of the radiation detection panel (110) can move with respect to the main plate (121). That is, since the adhesive surface (310) is biased to one side, the main plate (121) and the radiation detection panel (110) can enable the radiation detector (100) to provide bending. In addition, when the radiation detector (100) is bent, the radiation detection panel (110) may not be damaged by the main plate (121).

[0066] A detection panel guide (not shown) may be formed on the main plate (121). The detection panel guide may be formed in a shape extending left and right, and may be formed on at least a portion of the upper and lower sides of the main plate (121). The detection panel guide may be in a 'C' shape or a 'C' shape that is reversed left and right to surround at least a portion of at least one of the upper and lower sides of the radiation detection panel (110). The detection panel guide may be a passage for the radiation detection panel (110) to move when the radiation detector (100) is bent. Even if the radiation detector (100) is repeatedly bent and unfolded by the detection panel guide, the radiation detection panel (110) can always be bent or unfolded in the same shape. Therefore, the radiation detector (100) can always obtain a uniform radiation image.

[0067] According to various embodiments of the present disclosure, the adhesive surface (310) may be positioned at the center of the main plate (121) differently from FIG. 3. In this case, the center of the radiation detection panel (110) may be fixed with respect to the main plate (121). In addition, when the radiation detector (100) bends, one side and the other side of the radiation detection panel (110) may move with respect to the main plate (121), thereby enabling the radiation detector (100) to bend.

[0068] The main plate (121) may include a cable penetration hole (320). The cable penetration hole (320) may be a connection passage for a detector cable for connecting between the radiation detection panel (110) and the control board (210). The control board (210) may be located at the rear of the main plate (121). The rear may be in the opposite direction to the third direction.

[0069] Referring to FIG. 3 together with FIG. 2, a control board bracket (220) for attaching a control board (210) may be attached to the rear surface of the main plate (121). The control board bracket (220) may have a space formed therein for storing and fixing the control board (210). The control board bracket (220) may be fixed to the main plate (121) with screws. In addition, the control board (210) may be fixed to the control board bracket (220) with screws.

[0070] A control board (210) can be electrically connected to a radiation detection panel (110) by a detector cable. A radiation detector in which one end of the detector cable is connected to the radiation detection panel (110), the detector cable passes through a cable penetration hole (320), and the other end of the detector cable is connected to a control board (210) housed inside a control board bracket (220).

[0071] The control board (210) can transmit and receive signals with the radiation detection panel (110). In addition, the ground line of the control board (210) can be electrically connected to at least one of the control board bracket (220) and the main plate (121). That is, the ground area of ​​the control board (210) is expanded, and noise in the radiation image can be significantly reduced.

[0072] Referring back to FIG. 3, the radiation detector (100) may include a conductive gasket (122). The conductive gasket (122) may be adhered to at least a portion of the front surface of the main plate (121). The conductive gasket (122) may be arranged along a side surface of the radiation detection panel (110). The side surface may be a surface excluding the front and back surface of the conductive gasket (122). For example, the side surface may be a top surface, a left surface, a right surface, or a bottom surface. The conductive gasket (122) may be formed along the outer surface (edge) of the main plate (121). The entire rear surface (back surface) of the conductive gasket (122) may be in surface contact with the main plate (121). However, the present invention is not limited thereto, and at least a portion of the conductive gasket (122) may be in contact with at least a portion of the outer surface of the main plate (121).

[0073] The conductive gasket (122) may be a material that is both conductive and flexible, allowing for bending. For example, the conductive gasket (122) may be a conductive silicone material. For example, the conductive gasket (122) may be implemented using silicone (NBR, EPDM, etc.).

[0074] A panel receiving hole (330) for receiving a radiation detection panel (110) may be formed at the center of the conductive gasket (122). The conductive gasket (122) may have a closed curve shape, but is not limited thereto. The radiation detection panel (110) may be received in the panel receiving hole (330) of the conductive gasket (122) so that the conductive gasket (122) surrounds the radiation detection panel (110). The conductive gasket (122) may not be in contact with the radiation detection panel (110). The conductive gasket (122) may not be coupled with the radiation detection panel (110). The area where the radiation detection panel (110) is coupled to the main plate (121) and the area where the conductive gasket (122) is coupled may not overlap. However, it is not limited to this, and the conductive gasket (122) may also be in contact with or coupled to the radiation detection panel (110).

[0075] The conductive gasket (122) can be electrically connected to the main plate (121). As previously described, the main plate (121) can serve to expand the ground area of ​​the control board (210). The conductive gasket (122) can also be connected to the main plate (121) to expand the ground area. As previously described, by expanding the ground area, noise in the radiographic image can be reduced.

[0076] The conductive gasket (122) can be coupled to the front surface of the main plate (121). Both the conductive gasket (122) and the radiation detection panel (110) can be coupled to the front surface of the main plate (121). In addition, the entire rear surface of the conductive gasket (122) can be bonded to the main plate (121). However, it is not limited thereto, and at least a portion of the rear surface of the conductive gasket (122) can be bonded to at least a portion of the main plate (121). The conductive gasket (122) can be welded to the main plate (121) or bonded using a conductive double-sided tape or a conductive adhesive. However, it is not limited thereto, and the conductive gasket (122) can be bonded to the main plate (121) by a hardware structure. For example, the conductive gasket (122) can be screw-bonded to the main plate (121). The main plate (121) may be subjected to a process to increase conductivity at a portion where it is joined to the conductive gasket (122) in order to be electrically connected to the conductive gasket (122). For example, the main plate (121) may be subjected to a laser de-filming process at a portion where it is joined to the conductive gasket (122). To explain the main plate (121), reference will be made to FIG. 4 for a moment.

[0077] Figure 4 illustrates a main plate according to one embodiment of the present disclosure.

[0078] Referring to FIG. 4, the main plate (121) may include a non-removed portion (410) and a removed portion (420). The non-removed portion (410) may be in contact with the radiation detection panel (110). In addition, at least a portion of the non-removed portion (410) may have an adhesive surface (310) formed thereon. Accordingly, at least a portion of the non-removed portion (410) may be adhered to the radiation detection panel (110).

[0079] The de-filming treatment portion (420) of the main plate (121) may be a portion for joining with the conductive gasket (122). The de-filming treatment portion (420) may be treated to increase conductivity. Accordingly, the main plate (121) can be electrically connected to the conductive gasket (122) with low resistance.

[0080] A bracket coupling hole (430) for coupling with a control board bracket (220) may be formed in the non-removed portion (410) of the main plate (121). In addition, a screw coupling hole (440) for coupling with at least one of a conductive gasket (122) and a front plate (123) with a screw may be formed in the removable portion (420) of the main plate (121). At least one of the main plate (121), the conductive gasket (122), and the front plate (123) may be electrically connected to each other by an electrically conductive screw.

[0081] The main plate (121) may be formed integrally. That is, the main plate (121) may have the shape of a single panel rather than being a combination of various components. For example, the main plate (121) may be manufactured by cutting or folding a single plate of a predetermined material. However, the present invention is not limited thereto.

[0082] Referring back to FIG. 3, the radiation detector (100) may include a front plate (123). The front plate (123) may be bonded to the front surface of the conductive gasket (122). The entire front surface of the conductive gasket (122) may be bonded to the front plate (123). However, the present invention is not limited thereto, and at least a portion of the front surface of the conductive gasket (122) may be bonded to at least a portion of the front plate (123). The conductive gasket (122) may be welded to the front plate (123) or may be bonded using a conductive double-sided tape or a conductive adhesive. However, the present invention is not limited thereto, and the conductive gasket (122) may be bonded to the front plate (123) by a hardware structure. For example, the conductive gasket (122) may be screw-bonded to the front plate (123).

[0083] The front plate (123) can be electrically connected to the conductive gasket (122). In order to be electrically connected to the conductive gasket (122), the front plate (123) can be treated to improve conductivity at the portion where it is joined to the conductive gasket (122). For example, the front plate (123) can be subjected to laser de-filming at the portion where it is joined to the conductive gasket (122). The conductive gasket (122) can be electrically connected to the front plate (123). As previously described, the main plate (121) can serve to expand the ground area of ​​the control board (210). The front plate (123) can also be connected to the main plate (121) via the conductive gasket (122) to expand the ground area.

[0084] As described above, by increasing the ground area, noise in the radiation image can be reduced. More specifically, in the case of the control board (210), overcurrent or leakage current may occur, and in the case of the radiation detector (100), noise may occur in the image due to current radiated from at least one of the radiation detection panel (110) and the control board (210). In addition, overheating may occur in some chip materials in the control board (210) due to the radiated current. The radiation detector (100) of the present disclosure uses the front plate (123), the conductive gasket (122), and the main plate (121) to secure ground in a part where voltage flow is obstructed, and allows current to flow to the corresponding area, thereby preventing overheating of the radiation detector (100) and outputting a high-quality radiation image.

[0085] The front plate (123) can cover the front of the radiation detection panel (110). The back of the radiation detection panel (110) is covered by the main plate (121), the side of the radiation detection panel is surrounded by a conductive gasket (122), and the front of the radiation detection panel (110) can be covered by the front plate (123). That is, the radiation detection panel (110) can be sealed by the main plate (121), the conductive gasket (122), and the front plate (123). Of course, there is a cable penetration hole (320) in the main plate (121), but at least a portion of the cable penetration hole can be covered by the control board bracket (220). An adhesive for waterproofing may be used to join the main plate (121), the conductive gasket (122), the front plate (123), and the control board bracket (220). In this way, the primary waterproof structure of the radiation detector (100) can be implemented by surrounding the radiation detection panel (110) with at least one of the main plate (121), the conductive gasket (122), the front plate (123), and the control board bracket (220).

[0086] As previously described, at least a portion of the radiation detection panel (110) can be coupled with the adhesive surface (310) of the main plate (121). Only a portion of the radiation detection panel (110) is fixed to the main plate (121), and the remaining portion can move freely within the space formed by the main plate (121), the conductive gasket (122), the front plate (123), and the control board bracket (220). Therefore, the radiation detector (100) can be bent without applying a large force to the radiation detection panel (110), and the radiation detection panel (110) can be positioned in a fixed area within the radiation detector (100). In addition, even if the bending and unfolding of the radiation detector (100) is repeated, the radiation detection panel (110) can always be bent or unfolded in the same shape within the space formed by the main plate (121), the conductive gasket (122), the front plate (123), and the control board bracket (220). Therefore, the radiation detector (100) can always obtain a uniform radiation image, and the user can easily obtain a desired radiation image.

[0087] The front plate (123) may be flexible. Therefore, the front plate (123) may also bend according to the bending of the radiation detection panel (110).

[0088] The front plate (123) may be positioned in a third direction of the radiation detection panel (110) to protect the radiation detection panel (110). Here, the third direction may mean the front. The front plate (123) may have a larger area than the radiation detection panel (110) so as to cover the radiation detection panel (110). The front plate (123) may not be fixed to the radiation detection panel (110). In addition, since the front plate (123) is coupled to a flexible conductive gasket (122), the front plate (123) can flexibly respond to the bending motion of the radiation detector (100). In addition, even when the radiation detector (100) is bent due to the flexible conductive gasket (122), it may not be separated from the conductive gasket (122). Additionally, even if the radiation detector (100) is bent or unfolded by the flexible conductive gasket (122), the front plate (123) may not be separated from the main plate (121).

[0089] Since the front plate (123) is not directly connected to the radiation detection panel (110), the front plate (123) only protects the radiation detection panel (110), and can prevent the front plate (123) from causing damage to the radiation detection panel (110).

[0090] Additionally, the front plate (123) may be formed integrally. That is, the front plate (123) may have the shape of a single panel rather than being a combination of various components. For example, the front plate (123) may be manufactured by cutting or folding a single plate of a predetermined material. However, the present invention is not limited thereto.

[0091] Although not disclosed in FIGS. 1 to 3, the front plate (123) may include a front protection part (not shown) to protect the front plate (123). The front protection part may be detachable from the radiation detector. Since the front plate (123) is fixed to the radiation detector (100), if the front plate (123) is damaged, there is a burden of having to replace the radiation detector (100). In particular, if the subject is a rough object or the radiation detector (100) is used in a rough environment, the possibility of the front plate (123) being damaged increases, so the cycle of having to replace the radiation detector (100) may be shortened. The radiation detector (100) of the present disclosure has a replaceable front protection part that can contact or approach the subject in place of the radiation front plate (123). Accordingly, scratches will not occur on the front plate (123) but on the front protection part, and the user can easily maintain the radiation detector (100) by simply replacing the front protection part. In addition, if there is a detachable front protection part, the radiation detection panel (110) can be protected in double with the front plate (123). That is, the radiation detector (100) of the present disclosure can further increase the durability of the radiation detector (100) by having a detachable front protection part.

[0092] The thickness of the front plate (123) may be 0.1T or more and 1T or less. In addition, the material of the front plate (123) may be a material that transmits radiation. In addition, the material of the front plate (123) may be a material with resilience, so that it may be a material that can be restored to its original state even if bent by an external force. If the thickness of the front plate (123) exceeds 1.0T, the transmittance and yield strength decrease, so that it is difficult to use in a bendable radiation detector (100) and the quality of the radiation image may decrease. In addition, if the thickness of the front plate (123) is 0.1T or less, it may not only fail to function as a protective part but also have low durability. The front plate (123) may have a transmittance of 85% or more. In addition, if the front plate (123) has a transmittance lower than 85%, high energy band radiation must be irradiated to obtain a radiation image, which may have a negative effect on the control board (210) provided in the detector due to excessive energy exposure, and the subject's radiation exposure may increase. In order to protect the control board (210) from excessive energy exposure, if a front plate (123) of 1T or more is used, the front plate (123) may be damaged or not restored when bent, which may cause a problem. In addition, the yield strength of the front plate (123) may be 20 MPa or more and 30 MPa or less. For example, the yield strength of the front plate (123) may be 23 MPa. The front plate (123) having such physical characteristics maintains appropriate elasticity when bent, and can enable repeated bending and flat movement without affecting the radiation detection panel (110) and control board (210) of the radiation detector (100).

[0093] The material of the front plate (123) may be at least one of stainless steel sheet material, copper sheet material, and carbon tool steel. However, the present invention is not limited thereto, and the material of the front plate (123) may be a composite material sheet mixed with at least one of carbon, stainless steel, copper, and carbon tool steel. The carbon tool steel that can be used as the front plate (123) may be one of SK1, SK2, SK3, SK4, SK5, SK6, and SK7. In order to increase the surface hardness of the front plate (123), a post-processing may be performed on the material. For example, heat treatment, PVD, DLC, etc. may be performed on the material. The front plate (123) can maintain bendability and return to its original state by using the above-mentioned material and thickness. In addition, since it allows radiation to pass through, it may have little effect on the radiation image. In addition, the front plate (123) can secure strength sufficient to protect the radiation detection panel (110). As described above, at least one of optimal bendability, restorability, and radiation transparency of the front plate (123) can be secured by the material and thickness of the front plate (123), and this has been experimentally proven.

[0094] In addition, by minimizing the combination or contact between the front plate (123) and the radiation detection panel (110), damage to the radiation detection panel (110) caused by the front plate (123) can be minimized. This is because the front plate (123) can come into contact with and approach the subject and thus receive a large external force, but since this external force is not transmitted to the radiation detection panel (110) through the front plate (123), damage to the radiation detection panel (110) can be minimized.

[0095] Referring back to FIG. 2, the radiation detector (100) may include at least one of a pixel array, a readout signal unit, a gate driver circuit unit, and a control board (210). The radiation detector (100) may include a photodetector that detects radiation (X-rays) to generate an electric signal and a readout circuit unit that reads out the generated electric signal. The readout signal unit may be implemented with a plurality of ROICs (Read out ICs) in a film form, and each ROIC may be connected to the control board (210) by a connector. The readout circuit unit may be included in the radiation detection panel (110). The control unit may process the electric signal output from the readout circuit unit and then generate X-ray image data constituting an X-ray image. The generated X-ray image data may be stored in a memory together with (or separately from) detector status information or information related to X-ray photography. At least one of the control unit and the memory may be included in the control board (210).

[0096] In addition, the control board (210) may include at least one of a power supply unit for supplying power to the detector and a communication unit for communicating with an external device, either wired or wirelessly. In addition, the control board (210) may also include a sensor unit for determining one of the position and orientation of the detector.

[0097] In order to sequentially perform the operation of detecting X-ray information in the radiation detector (100) and transmitting it to an external computer, the radiation detector (100) may use a power and data cable that transmits power (or power) supply and data communication together.

[0098] Additionally, the control board (210) of the radiation detector (100) can utilize WiFi and Gigabit Ethernet for wired and wireless data transmission. In addition, the control unit of the radiation detector (100) can be connected to communicate with a workstation for variables for driving the image sensor, etc.

[0099] As described in Fig. 2, a combination of at least one of a radiation detection panel (110), a main plate (121), a conductive gasket (122), a front plate (123), a control board bracket (220), and a control board (210) may be referred to as a detector core module (230). Hereinafter, a configuration for further enhancing the waterproof performance of the radiation detector (100) will be described.

[0100] FIG. 5 is a drawing showing a portion of a radiation detector according to one embodiment of the present disclosure. FIG. 6 is a drawing showing a cross-section of a portion of a radiation detector according to one embodiment of the present disclosure.

[0101] Referring to FIGS. 5 and 6, the radiation detector (100) may include a rear elastic jacket (124). The rear elastic jacket (124) may cover at least a portion of the rear surface of the main plate (121) of the detector core module (230), at least a portion of the side surface of the main plate (121), the side surface of the conductive gasket, the side surface of the front plate, and at least one of the control board bracket. In addition, the rear elastic jacket (124) may be a material having elasticity. For example, it may be implemented with at least one material of rubber, silicone, and urethane.

[0102] Referring to FIG. 5, the rear elastic jacket (124) may include a control board storage portion (511). The control board storage portion (511) may have a concave shape for storing and protecting the control board bracket (220). The control board storage portion (511) may also store the control board (210).

[0103] The rear elastic jacket (124) may include a side protrusion (512). The side protrusion (512) may be the remaining portion of the rear elastic jacket (124) excluding the control board storage portion (511). The side protrusion (512) may be formed along the edge of the rear elastic jacket (124). The side protrusion (512) may include a forwardly protruding configuration to protect at least a portion of the side of the main plate (121), the side of the conductive gasket (122), and the side of the front plate (123).

[0104] Referring to FIG. 6, from the rear to the front, a control board bracket (220), a main plate (121), a conductive gasket (122), and a front plate (123) may be positioned. If there is no rear elastic jacket (124), at least a portion of the rear surface or at least a portion of the side surface of the control board bracket (220), the main plate (121), the conductive gasket (122), and the front plate (123) is exposed. The rear elastic jacket (124) may surround at least a portion of the rear surface or at least a portion of the side surface of the control board bracket (220), the main plate (121), the conductive gasket (122), and the front plate (123). For example, a control board storage portion (511) included in the rear elastic jacket (124) may surround the rear and side surfaces of the control board bracket (220). Additionally, the side protrusion (512) included in the rear elastic jacket (124) can wrap at least a portion of the rear surface or at least a portion of the side surface of the main plate (121), the conductive gasket (122), and the front plate (123). Referring to Fig. 6, the front surface of the front plate (123) can be exposed to the outside.

[0105] Additionally, the rear elastic jacket (124) may not be adhesively bonded to at least a portion of the rear surface or at least a portion of the side surface of the main plate (121), the conductive gasket (122), and the front plate (123). This is to facilitate bending of the radiation detector (100).

[0106] In this way, the rear elastic jacket (124) may be configured to protect at least one of the rear and side surfaces of the detector core module (230). In addition, the rear elastic jacket (124) may prevent foreign substances from entering from at least one of the rear and side surfaces of the detector core module (230). The thickness of the rear elastic jacket (124) may be 0.5T or more and 3.0T or less. If the thickness of the rear elastic jacket (124) is 0.5T or less, it may be easily torn during bending. In addition, if the thickness of the rear elastic jacket (124) is 3T or more, not only will bending not be performed smoothly, but there is a risk of deformation of other parts (wrinkling or stretching, inflow of foreign substances due to deformation of the airtight portion, etc.) in order to secure the length value that increases during forcible bending.

[0107] Below, the structure in which the rear elastic jacket (124), main plate (121), conductive gasket (122), and front plate (123) are fixed is described in more detail.

[0108] FIG. 7 illustrates a portion of a radiation detector according to an embodiment of the present disclosure. FIG. 8 illustrates a lateral elastic jacket according to an embodiment of the present disclosure. Additionally, FIG. 9 illustrates a cross-section of a portion of a radiation detector according to an embodiment of the present disclosure.

[0109] Referring to Fig. 7, the radiation detector (100) may further include a side elastic jacket (125). Fig. 7 illustrates a process of combining the side elastic jacket (125) with a detector core module (230) to which a rear elastic jacket (124) is combined.

[0110] Referring to FIGS. 7 and 9, the side elastic jacket (125) can be formed along the side protrusion (512) of the rear elastic jacket (124) to wrap the side protrusion (512) formed on the side of the rear elastic jacket (124).

[0111] Fig. 8 (a) is a perspective view showing a portion of a side elastic jacket (125). Referring to Fig. 8 (a), the inner circumferential surface of the side elastic jacket (125) may include a side protection recess (810) for inserting a side protrusion (512). The side protection recess (810) may be formed along the side elastic jacket (125). The side protection recess (810) may be formed between the front and rear portions of the side elastic jacket (125). The front portion is one side located in front of the side protection recess (810), and the rear portion is the other side located in the rear of the side protection recess (810). The front portion and the rear portion may be substantially parallel. The front portion and the rear portion may be connected by the side portion. The cross-section of the side elastic jacket (125) may have a 'C' shape or a 'C' shape that is reversed left and right by the front, rear, and side portions forming the side protection concave portion (810).

[0112] Fig. 8 (b) is a front view showing a portion of the side elastic jacket (125). Referring to Fig. 8 (b), a diagonally formed cut line (850) may be formed at the corner portion of the side elastic jacket (125). More specifically, the upper left, lower left, lower right, and upper right corners of the side elastic jacket (125) may include a cut line (850) to assist in coupling with the side protrusion (512) of the rear elastic jacket (124). By means of the cut line (850), the side elastic jacket (125) can be easily coupled to the detector core module (230) to which the rear elastic jacket (124) is coupled.

[0113] Referring to (a) of FIG. 8, the side elastic jacket (125) may include a front concave portion (820). More specifically, the front concave portion (820) may be formed on the front surface of the front portion of the side elastic jacket (125). The front concave portion (820) may be configured to insert a front base bracket (1010) into the front surface of the side elastic jacket (125). The front base bracket (1010) is configured to secure the side elastic jacket (125) to the detector core module (230) to ensure waterproofing of the radiation detector (100). The size of the front concave portion (820) may be the same as the size of the front base bracket (1010).

[0114] Referring to (a) of Fig. 8, at least one bending groove (840) extending vertically may be formed between a plurality of front concave portions (820). The bending groove (840) may be configured to assist the radiation detector (100) in bending around an axis extending vertically.

[0115] Referring to (a) of FIG. 8, the side elastic jacket (125) may include a rear concave portion (920). More specifically, the rear concave portion (920) may be formed on the rear side of the rear portion of the side elastic jacket (125). The rear concave portion (920) may be configured to allow a rear base bracket (1020) to be inserted into the rear side of the side elastic jacket (125). The rear base bracket (1020) may be configured to secure the side elastic jacket (125) to the detector core module (230) to ensure waterproofing of the radiation detector (100). The size of the rear concave portion (920) may be the same as the size of the rear base bracket (1020).

[0116] At least one vertically extending bending groove may be formed between the plurality of rear recesses (920). The bending groove may be configured to assist the radiation detector (100) in bending around the vertically extending axis.

[0117] A screw hole (830) may be formed in the front concave portion (820). In addition, a screw hole may also be formed in the rear concave portion (920). The front base bracket (1010) may be inserted into the front concave portion (820), and the rear base bracket (1020) may be inserted into the rear concave portion. In addition, at least one of the front base bracket (1010), the side elastic jacket (125), the front plate (123), the conductive gasket (122), the main plate (121), the rear elastic jacket (124), and the rear base bracket may be screw-connected. More specifically, at least one of the front base bracket (1010), the front part of the side elastic jacket (125), the front plate (123), the conductive gasket (122), the main plate (121), the side protrusion (512) of the rear elastic jacket (124), the rear part of the side elastic jacket (125), and the rear base bracket can be screwed together in the mentioned order.

[0118] Figure 9 (a) shows a position for indicating a cross-section. Figure 9 (b) shows a cross-section at the position indicated in Figure 9 (a). More specifically, Figure 9 (b) shows a cross-section at the position where the front concave portion (820) and the rear concave portion (920) are formed. The part already explained in Figure 6 in the description of Figure 9 (b) is omitted.

[0119] Referring to (b) of FIG. 9, the side elastic jacket (125) can be formed along the side protrusion (512) of the rear elastic jacket (124) to wrap the side protrusion (512) formed on the side of the rear elastic jacket (124).

[0120] After the side elastic jacket (125) is combined, the front part of the side elastic jacket (125), the front plate (123), the conductive gasket (122), the main plate (121), the rear elastic jacket (124), and the rear part of the side elastic jacket (125) may be arranged from the front to the rear in the area of ​​the side protrusion (512) of the rear elastic jacket (124). In addition, a front concave part (820) may be formed on the front part of the side elastic jacket (125). In addition, a rear concave part (920) may be formed on the rear part of the side elastic jacket (125).

[0121] In addition, the side elastic jacket (125) may be made of an elastic material. For example, it may be made of at least one of rubber, silicone, and urethane. The thickness of the side elastic jacket (125) may be 0.5T or more and 3.0T or less. If the thickness of the side elastic jacket (125) is 0.5T or less, it may be easily torn during bending. In addition, if the thickness of the side elastic jacket (125) is 3T or more, not only will bending not be performed smoothly, but there is a risk of deformation of other parts (wrinkling or stretching, inflow of foreign substances due to deformation of the sealing part, etc.) in order to secure the length value increased during forcible bending. Therefore, it is advantageous for the thickness of the side elastic jacket (125) to be 0.5T or more and 3.0T or less, and this has been proven through experiments.

[0122] FIG. 10 is a drawing for explaining a radiation detector according to one embodiment of the present disclosure.

[0123] FIG. 10 is a drawing for explaining a process of combining at least one of a front base bracket (1010), a rear base bracket (1020), and a rear base module (1030) after combining a side elastic jacket (125) to a radiation detector (100) as described in FIGS. 7 to 9.

[0124] At least one of the front base bracket (1010) and the rear base bracket (1020) may have lower elasticity than the material of the side elastic jacket (125) and the rear elastic jacket (124). For example, the front base bracket (1010) and the rear base bracket (1020) may be made of metal or plastic. However, the present invention is not limited thereto, and various materials having lower elasticity than the material of the side elastic jacket (125) and the rear elastic jacket (124) may be used as the material of the front base bracket (1010) and the rear base bracket (1020). In this way, since at least one of the front base bracket (1010) and the rear base bracket (1020) has lower elasticity than the material of the side elastic jacket (125) and the rear elastic jacket (124), when the front base bracket (1010) and the rear base bracket (1020) are combined with the side elastic jacket (125) and the rear elastic jacket (124), there is an effect in which the side elastic jacket (125) and the rear elastic jacket (124) are compressed by an area equal to that of the front base bracket (1010) and the rear base bracket (1020).

[0125] Since the area of ​​the front base bracket (1010) and the rear base bracket (1020) is larger than the area of ​​the screw for joining, the front base bracket (1010) and the rear base bracket (1020) have the effect of compressing a wider area than using only the screw. Therefore, the front base bracket (1010) and the rear base bracket (1020) of the radiation detector (100) of the present disclosure can firmly fix the side elastic jacket (125) and the rear elastic jacket (124) to the radiation detector (100). In addition, the side elastic jacket (125) and the rear elastic jacket (124) may not be crushed or torn by the front base bracket (1010) and the rear base bracket (1020). Therefore, the waterproof performance of the radiation detector (100) can be improved and its durability can also be improved.

[0126] Unlike Fig. 10, the front base bracket (1010) may be formed integrally. That is, the front base bracket (1010) may have a closed curve shape. The front base bracket (1010) may be formed along the side elastic jacket (125). However, it is not limited thereto. The front base bracket (1010) may be divided into a plurality of pieces. The front base bracket (1010) may include a left front base bracket (1012), a right front base bracket (1013), and a plurality of central front base brackets (1011).

[0127] The left front base bracket (1012) is coupled to the left side of the front of the side elastic jacket (125) and may have a 'C' shape (or a 'ㄷ' shape) when viewed from the front. The right front base bracket (1013) is coupled to the right side of the front of the side elastic jacket (125) and may have a shape that is a 'C' shape that is inverted left and right. A plurality of central front base brackets (1011) may be coupled to the front of the side elastic jacket (125). The plurality of central front base brackets (1011) may be arranged between the left front base bracket (1012) and the right front base bracket (1013). The plurality of central front base brackets (1011) may be arranged side by side along the side elastic jacket (125). A plurality of central front base brackets (1011) can be formed along the edges of the side elastic jacket (125) and the front plate (123).

[0128] Referring briefly to (a) of FIG. 8, the front concave portion (820) of the central portion included in the side elastic jacket (125) may have a shape corresponding to the central front base bracket (1011). Also, referring to (b) of FIG. 8, the right front concave portion (860) included in the side elastic jacket (125) may have a shape corresponding to the right front base bracket (1013). In addition, although not shown, the left front concave portion included in the side elastic jacket (125) may have a shape corresponding to the left front base bracket (1012).

[0129] The left front base bracket (1012), the right front base bracket (1013), and a plurality of central front base brackets (1011) can be inserted into the front recesses (820, 860). That is, the central front base bracket (1011) can be inserted into the front recess (820) of the central portion included in the side elastic jacket (125). In addition, referring to (b) of FIG. 8, the right front base bracket (1013) can be inserted into the right front recess (860) included in the side elastic jacket (125). In addition, although not shown, the left front base bracket (1012) can be inserted into the left front recess included in the side elastic jacket (125).

[0130] Referring to Fig. 8, at least one vertically extending bending groove (840) may be formed between the front concave portions (820) of the plurality of central portions corresponding to the plurality of central front base brackets (1011). At least one vertically extending bending groove may also be formed between the plurality of rear concave portions (920). The bending groove (840) may be configured to assist the radiation detector (100) in bending around the vertically extending axis.

[0131] The radiation detector (100) may include a rear base module (1030). The rear base module (1030) may be located at the rear of the rear elastic jacket (124). The rear base module (1030) may be configured to protect the control board (210) inside the control board bracket (220). As previously described, the rear elastic jacket (124) may be made of an elastic material. The rear elastic jacket (124) may support bending of the radiation detector (100) and provide waterproofing, but may be insufficient to protect the control board (210). Therefore, the rear base module (1030) may be implemented with a hard material to protect the control board (210). For example, the rear base module (1030) may be implemented with plastic, metal, or the like. The rear base module (1030) may be implemented with a plurality of pieces to support bending of the radiation detector (100). A rear base bracket (1020) may be positioned between the plurality of rear base modules (1030). The areas of the plurality of rear base modules (1030) and the area of ​​the rear base bracket (1020) may not overlap each other in the left-right direction. Therefore, bending of the radiation detector (100) may be supported based on at least one of the rear base modules (1030) and the rear base bracket (1020) divided into a plurality of pieces.

[0132] The radiation detector (100) may include both a rear base module (1030) and a rear base bracket (1020). However, this is not limited thereto, and the radiation detector (100) may include only one of the rear base module (1030) and the rear base bracket (1020).

[0133] The rear base module (1030) may have lower elasticity than the materials of the side elastic jacket (125) and the rear elastic jacket (124). For example, the rear base module (1030) may be made of metal or plastic. However, the present invention is not limited thereto, and various materials having lower elasticity than the materials of the side elastic jacket (125) and the rear elastic jacket (124) may be used as the material of the rear base module (1030). In this way, since the rear base module (1030) has lower elasticity than the materials of the side elastic jacket (125) and the rear elastic jacket (124), when the rear base module (1030) is combined with the side elastic jacket (125) and the rear elastic jacket (124), the side elastic jacket (125) and the rear elastic jacket (124) have the effect of being compressed by an area equal to that of the rear base module (1030).

[0134] Since the area of ​​the rear base module (1030) is larger than the screw for bonding, the rear base module (1030) has the effect of compressing a wider area than using only the screw. Therefore, the rear base module (1030) of the radiation detector (100) can firmly fix the side elastic jacket (125) and the rear elastic jacket (124) to the radiation detector (100). In addition, the side elastic jacket (125) and the rear elastic jacket (124) may not be crushed or torn due to the rear base module (1030). Therefore, the waterproof performance of the radiation detector (100) may be improved and the durability may also be improved. Refer to FIG. 13 to explain various embodiments of the side elastic jacket (125).

[0135] FIG. 13 is a drawing showing a side elastic jacket according to one embodiment of the present disclosure.

[0136] Fig. 13(a) shows a perspective view of a side elastic jacket (1310). In addition, Fig. 13(b) shows a cross-sectional view of the side elastic jacket (1310) taken along line A-A' of the side elastic jacket of Fig. 13(a). Fig. 13(b) shows a cross-sectional view of the side elastic jacket (1310) taken along line C-C' of the side elastic jacket of Fig. 13(a). Fig. 13(c) shows the back side of Fig. 13(a).

[0137] Referring to Fig. 13, the side elastic jacket (1310) may have a different shape from that of Figs. 7 to 9. More specifically, the side elastic jacket (1310) may be of a shape that completely covers at least one of the front or rear sides of the core module (230). The side elastic jacket (1310) may include at least one of a front cover (1311) and a rear cover (1312).

[0138] According to one embodiment of the present disclosure, the side elastic jacket (1310) can cover the front of the core module (230).

The side elastic jacket (1310) can be formed integrally and can include the front cover (1311). The front cover (1311) of the side elastic jacket (1310) can be in contact with at least a portion of the core module (230). The front cover (1311) of the side elastic jacket (1310) can be in contact with at least one of the radiation detection panel (110), the main plate (121), the conductive gasket (122), and the front plate (123). The rear surface of the front cover (1311) of the side elastic jacket (1310) can be in contact with the front surface of at least one of the radiation detection panel (110), the main plate (121), the conductive gasket (122), and the front plate (123) of the core module (230).

[0139] Referring to (b) and (c) of FIG. 13, the rear cover (1312) of the side elastic jacket (1310) may cover at least a portion of the rear surface of the core module (230). For example, the rear cover (1312) of the side elastic jacket (1310) may be formed along the edge of the rear surface of the core module (230). Since the rear cover (1312) is formed along the edge of the rear surface of the core module (230), the rear surface of the front cover (1311) may be visible in FIG. 13 (c), which is a view of the side elastic jacket (1310) from behind.

[0140] However, it is not limited to Fig. 13, and other embodiments are possible. The side elastic jacket (1310) can cover the entire rear surface of the core module (230). The side elastic jacket (1310) can be formed integrally and can include a rear cover (not shown). The rear cover of the side elastic jacket (1310) can be in contact with at least a portion of the core module (230). The rear cover of the side elastic jacket (1310) can be in contact with at least one of the radiation detection panel (110), the main plate (121), the conductive gasket (122), and the front plate (123). The front surface of the rear cover of the side elastic jacket (1310) can be in contact with the rear surface of at least one of the radiation detection panel (110), the main plate (121), the conductive gasket (122), the front plate (123), the control board bracket (220), and the control board (210) of the core module (230). In addition, the front cover can be formed along the edge of the core module (230) to cover at least a portion of the front surface of the core module (230).

[0141] A side elastic jacket (1310) including at least one of a front cover (1311) and a rear cover can prevent foreign substances from entering at least one of the front and rear sides of the side elastic jacket (1310). In this way, since the side elastic jacket (1310) includes at least one of the front cover (1311) and the rear cover, the side elastic jacket (1310) can firmly prevent foreign substances from entering the core module (230) inside the side elastic jacket (1310). In addition, the side elastic jacket (1310) can improve the waterproof function of the radiation detector (100). FIG. 11 is a drawing showing a cross-section of a radiation detector according to an embodiment of the present disclosure.

[0142] Referring to (a) of Fig. 11, a screw hole may also be formed in the front base bracket (1010). Referring to (b) of Fig. 11, at least one of the front base bracket (1010), the side elastic jacket (125), the conductive gasket (122), the rear elastic jacket (124), and the rear base bracket (1020) may be screw-connected. More specifically, in the area of ​​the side protrusion (512), at least one of the front base bracket (1010), the front portion of the side elastic jacket (125), the front plate (123), the conductive gasket (122), the main plate (121), the side protrusion (512) of the rear elastic jacket (124), the rear portion of the side elastic jacket (125), and the rear base bracket (1020) may be screw-connected while being positioned from the front to the rear in the mentioned order. When screwing, a washer can be additionally used to prevent the screw from loosening and improve the fixing force. For example, the washer can be positioned between two adjacent components among the front base bracket (1010), the front part of the side elastic jacket (125), the front plate (123), the conductive gasket (122), the main plate (121), the side protrusion (512) of the rear elastic jacket (124), the rear part of the side elastic jacket (125), and the rear base bracket (1020), or can be positioned on the front of the front base bracket (1010) or on the rear of the rear base bracket (1020).

[0143] FIG. 12 is a cross-sectional view of a radiation detector according to one embodiment of the present disclosure.

[0144] Fig. 12 may show a state in which a rear base module (1030) is combined instead of a rear base bracket (1020).

[0145] Figure 12 (a) shows a position for indicating a cross-section. Figure 12 (b) shows a cross-section at the position B-B' shown in Figure 12 (a). More specifically, Figure 12 (b) shows a cross-section at the position where the front base bracket (1010) and the rear base module (1030) appear.
