Description

Radiation detector including a support

[0001] The present invention relates to a radiation detector comprising a support member. The radiation detector of the present invention has excellent rigidity, so even when a heavy object is placed on it and a radiation image is taken, the radiation detector hardly deforms, thus having high durability and enabling the acquisition of high-quality images.

[0002] A radiation imaging system is a system designed to acquire images of the interior of an object and includes a radiation source and a radiation detector. The radiation source irradiates an object, such as the human body or an object, with radiation, and the radiation detector receives the radiation that has passed through the object and converts it into an electrical signal to generate a radiation image. A radiation imaging system utilizes the property that X-rays are absorbed or transmitted depending on the characteristics of the material through which they pass when irradiated onto an object.

[0003] Since radiation detectors are manufactured with a thickness of 15 mm or less, problems may arise where the panel is damaged due to external impact or deformation. Therefore, it is necessary to protect the panel by reinforcing the structural rigidity to improve the durability of the detector and mitigating the impact caused by external forces.

[0004] The present disclosure relates to a bendable radiation detector that provides improved radiation imaging. The radiation detector can prevent external material from penetrating into the interior of the radiation detector while providing improved radiation imaging.

[0055] Below, embodiments are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present disclosure. In addition, parts of the drawings that are irrelevant to the description are omitted to clearly explain the present disclosure.

[0056] FIG. 1 is a drawing showing a radiation detector according to one embodiment of the present disclosure.

[0057] The radiation detector (100) may include a rear surface (101) and a front surface (102). The front surface (102) and the rear surface may include carbon material.

[0058] The detector (100) may further include a battery (1030). The detector (100) may include a space for mounting the battery (1030). Additionally, the detector (100) may include a coil (1010) for supporting wireless charging. The radiation detector (100) of the present disclosure will be described in more detail below.

[0059] The radiation detector (100) of the present disclosure may be configured to detect radiation, generate an electrical signal, and generate a radiation image based on the electrical signal. The radiation detector (100) may detect radiation emitted from a radiation source and transmitted through an object. The radiation may include at least one of X-rays, gamma rays, and some ultraviolet rays. The radiation detector (100) may detect radiation and obtain a radiation image of the object. 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) may have a waterproof structure or be bendable. First

[0060] The radiation detector (100) of the present disclosure may include a housing (120) to protect the internal components from external forces. Additionally, the housing (120) may provide a waterproof function and may be bendable. The housing (120) will be described in detail later.

[0061] The radiation detector (100) may include a radiation detection panel (110). Depending on the method of acquiring the electrical signal, the detection panel (110) can be divided into a direct conversion type that obtains an indirect electrical signal from visible light using a scintillator and a direct conversion type that obtains a direct electrical signal from radiation using photoconductors. Depending on the type of device that generates the electrical signal, it can be classified into a CCD type that uses a Charge-Coupled Device, a CMOS type that uses a CMOS device of crystalline silicon, and an a-Si type that uses a TFT (Thin Film Transistor) substrate of amorphous silicon.

[0062] A radiation detector (100) including a detection panel (110) is equipped with various sensors and can implement digital image data using electrical signals and position information of the sensors in proportion to the incident amount of radiation. The radiation detector (100) can obtain shooting results close to real-time, secure high resolution and a wide dynamic range with relatively low radiation, and, due to the characteristics of digital data, storage and processing of shooting results are easy. The radiation detector (100) includes a readout signal unit that reads electrical signals output from a pixel array, and a gate driver that turns on a switching element so that the readout signal unit can read electrical signals. The electrical signal detected by the readout signal unit is converted into an image signal through a certain processing step in a controller, etc., provided on a main board, and then transmitted to a display device for displaying X-ray images.

[0063] The radiation detection panel (110) can detect radiation incident on the first surface. Here, the first surface may refer to the front surface of the radiation detection panel (110). The radiation detection panel (110) may be flexible. That is, the radiation detection panel may be flexible and bendable. If the surface of the subject has a rounded surface, the radiation detection panel (110) may be bent and adhere to the surface of the subject. Since the radiation detection panel (110) is positioned in close contact with the surface of the subject, the sharpness of the radiation image may be increased.

[0064] The radiation detector (100) may include a housing (120). The housing (120) may be in contact with at least one of a first surface of the radiation detection panel (110), a second surface facing the first surface, and a third surface excluding the first surface and the second surface. The second surface may refer to the rear surface of the radiation detection panel (110). The third surface may refer to the side surface of the radiation detection panel. For example, the third surface may include at least one of the top surface, the left side surface, the right side surface, and the bottom surface.

[0065] The housing (120) may be a component for protecting 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. Additionally, if external material 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 housing (120) can prevent the circuits included in the radiation detection panel (110) and the radiation detector (100) from being damaged by external impact, mitigate external impact, and prevent external material from entering the interior of the radiation detector (100).

[0066] Additionally, the housing (120) can support the radiation detection panel (110). The housing (120) may be configured to maintain the shape of the radiation detection panel (110). The housing (120) may be made of a rigid material so that the radiation detection panel (110) can maintain a flat shape even when subjected to external force.

[0067] According to various embodiments of the present disclosure, since the radiation detection panel (110) may be flexible and bendable, it may be difficult to keep the radiation detection panel (110) still relative to the subject without the housing (120). This is because the radiation detection panel (110) will easily be deformed by the movement of the subject or external force. Therefore, the housing (120) may be a component for supporting the radiation detection panel (110) to maintain a certain shape after it is bent. The housing (120) can control the bending of the radiation detection panel (110) around a bending axis parallel to the first direction that intersects the second direction. That is, the radiation detection panel (110) can also be bent to the extent that the housing (120) is bent. Here, the first direction may be an upward direction. However, it is not limited thereto, and the first direction may be a downward direction.

[0068] The housing (120) may include various configurations for the operation of the radiation detector (100). For example, the housing (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 housing (120) may include a control board (1040), and the control board may include at least one of a control unit, a communication unit, an input unit, and an output unit.

[0069] Below, the internal structure of the detector (100) is described in detail.

[0070] FIG. 2 shows a portion of a cross-section of a radiation detector according to one embodiment of the present disclosure.

[0071] Figure 2 shows a cross-section cut perpendicular to the front surface of the detector (100).

[0072] As previously explained, the detector (100) may include a housing (120). The housing (120) may include a front (121) of the housing, a side (122) of the housing, and a rear (123) of the housing. The front (121) of the housing, the side (122) of the housing, and the rear (123) of the housing may be connected to each other. At least two of the front (121) of the housing, the side (122) of the housing, and the rear (123) of the housing may be formed integrally. However, it is not limited thereto.

[0073] The detector (100) may include a detection panel (110). The detection panel (110) may be configured to be contained within a housing (120) and to detect radiation.

[0074] The detector (100) may include a middle plate (210). The middle plate (210) may be contained within a housing (120). The middle plate (210) may come into contact with a detection panel (110). The middle plate (210) may come into contact with the back of the detection panel (110). The middle plate (210) may support the detection panel (110). The middle plate (210) may be a component for fixing the detection panel (110). The detection panel (110) may not move relative to the middle plate (210). The middle plate (210) may be made of a rigid material. The middle plate (210) may allow the detector (100) to have a specific shape. Through the middle plate (210), the detection panel (110) can acquire a uniform radiation image.

[0075] The detector (100) may include a support member (230). The support member (230) may be connected to the middle plate (210). The support member (230) may be connected to the back of the middle plate (210). The support member (230) may be screw-coupled to the middle plate (210) or connected by an adhesive.

[0076] The support member (230) can be connected by an adhesive layer formed on one end surface of the middle plate (210). That is, an adhesive layer may be located between the support member (230) and the middle plate (210). The adhesive layer may be configured to combine the support member (230) and the middle plate (210). An adhesive may be applied to the front surface and the upper surface of the adhesive layer. For example, the adhesive layer may be double-sided tape.

[0077] The support member (230) may be connected to the middle plate (210) by at least one fastening screw.

[0078] The support member (230) can support the middle plate (210). The middle plate (210) has a plate shape, and when an external force is applied, it may be difficult to maintain the shape of the detector (100) using only the middle plate (210). The support member (230) can assist the middle plate (210) to ensure that the detector (100) always maintains a constant shape. The support member (230) can be implemented with a rigid material. The material of the support member (230) may include at least one of metal, plastic, carbon, or composite material. The support member (230) may include a metal material such as aluminum, Mg, Ti, or steel. Additionally, the support member (230) may include a plastic such as at least one of PC (polycarbonate), PP (polypropylene), or PA (polyamide). The support member (230) may include carbon. Additionally, the support member (230) may include a composite material comprising at least two of metal, plastic, PC, PP, PA, or carbon. However, it is not limited thereto.

[0079] The support member (230) can be connected to the rear side (123) of the housing. The support member (230) can be connected to the front side of the rear side (123) of the housing. The support member (230) can be screw-coupled to the rear side (123) of the housing or connected by adhesive.

[0080] By means of the support member (230), the components included in the detector (100) can always have a constant shape, and the external force applied to the detector (100) can be dispersed. Therefore, the detector (100) has the effect of always being able to acquire a uniform radiation image.

[0081] The cross-section of the support member (230) may have a shape that is part of a trapezoid or part of an inverted trapezoid. Additionally, the cross-section of the support member (230) may have a shape that is part of a polygon, part of an ellipse, or part of a circle. For example, the cross-section of the support member (230) may have a shape that is part of a rectangle, part of a triangle, part of an inverted triangle, part of a pentagon, part of a hexagon, part of an ellipse, or part of a circle. FIG. 2 illustrates the case where the cross-section of the support member (230) has a shape that is part of a trapezoid. Being part of a trapezoid may indicate that the support member (230) has a shape that widens as it goes from the front to the back. Being part of an inverted trapezoid may indicate that the support member (230) has a shape that widens as it goes from the back to the front.

[0082] When the cross-section of the support member (230) is trapezoidal, the effect of the support member (230) on the image can be minimized. In addition, since a bent portion is formed in the support member, the rigidity is increased, and even if the length of the support member (230) is reduced, high rigidity can be secured, thereby enabling weight reduction.

[0083] The detector (100) may further include an elastic filler in the concave portion (231) formed by the support member (230). The filler may include EPP (Expanded Polypropylene). The filler is not limited to this as long as it is an elastic material. Additionally, the detector (100) may also include a filler in an area (232) other than the concave portion (231) formed by the support member (230). Furthermore, at least one of the components of the detector (100) may be located in the concave portion (231). For example, a control board may be located in the concave portion (231). After the control board is located in the concave portion (231), the remaining space may be filled with a filler. However, it is not limited to this.

[0084] Referring to FIG. 2, an elastic layer (220) may be included between the front surface (121) of the detection panel (110) and the housing (120). The elastic layer may be implemented as PORON. However, it is not limited thereto, and elastic materials such as rubber, silicone, or urethane may be used. The elastic layer (220) can prevent external forces applied to the front surface (121) from being transmitted directly to the detection panel (110). Therefore, especially since an object is located in front of the front surface (121), there may be many cases where external forces are applied to the front surface of the detection panel (110). By absorbing the external forces applied to the front surface of the detection panel (110), the elastic layer (220) has the effect of enabling the detector to acquire high-quality radiation images. Additionally, the elastic layer (220) may fill the space between the front surface (121) and the detection panel (110), thereby allowing the detection panel (110) to always remain in a flat state. Therefore, the detection panel (110) can maintain a flat state, which is optimal for acquiring radiation images.

[0085] FIG. 3 is a drawing for explaining a middle plate according to one embodiment of the present disclosure.

[0086] FIG. 4 is a drawing for explaining the arrangement of a support member according to one embodiment of the present disclosure.

[0087] FIG. 3 may be a perspective view of a middle plate (210) viewed from behind according to one embodiment of the present disclosure. As previously described, the middle plate (210) may be a configuration for supporting a detection panel (110). If the housing (120) is the exoskeleton of the detector (100), the middle plate (210) may be the endoskeleton of the detector (100). The middle plate (210) may have an area nearly equal to that of the detection panel (110). The detection panel (110) may come into contact with the front of the middle plate (210). The middle plate (210) may come into contact with the entire area of ​​the detection panel (110). Due to the middle plate (210), the detection panel (110) may always have a flat shape.

[0088] The detector (100) may further include a support member (230) to support the detection panel (110) more robustly. The support member (230) can prevent the detector (100) from warping. Additionally, the support member (230) can protect the detector (100) from external forces. Furthermore, by positioning the main components of the detector (100) in the space between the support member (230) and the middle plate (210) and in the space between the support member (230) and the housing (120), the main components can be protected from being affected by external forces. Therefore, the detector of the present disclosure has the effect of increasing durability. In particular, the detector (100) of the present disclosure has the effect of preventing defects in which the detection panel breaks due to external forces.

[0089] FIG. 4 is a rear view of the detector (100). Referring to FIG. 4, a support member (230) may be formed in at least a portion of the area of ​​the middle plate (210). The support member (230) may be connected to the middle plate (210). The support member (230) may be connected to an area of ​​the support member included in at least a portion of the area of ​​the middle plate. Here, the area of ​​the support member (230) or the area of ​​the middle plate (210) may refer to an area in the plane formed by the first direction and the second direction. The area of ​​the support member may be smaller than or equal to the area of ​​the middle plate. The area of ​​the support member (230) may be included in the area of ​​the middle plate (210). The support member (230) may be connected to a portion of the area of ​​the middle plate (210). For example, the support member (230) may be formed along the edge of the middle plate (210). However, it is not limited to this, and the support member (230) may occupy an area including the center of the middle plate (210).

[0090] The support member (230) may be implemented as one of the first type of support member (410), the second type of support member (420), the third type of support member (430), and the fourth type of support member (440). The present disclosure is described based on the fourth type of support member (440). However, it is not limited thereto, and the support member (230) may be implemented as one of the first to fourth types, as well as as a form different from the first to fourth types.

[0091] The first type of support member (410) can be formed integrally. Since the first type of support member (410) is formed integrally, assembly may be good.

[0092] The second type of support member (420) may include a plurality of sub-support members (421 to 424). More specifically, the second type of support member (420) may include a first support member (421), a second support member (422), a third support member (423), and a fourth support member (424). The first support member (421) and the third support member (423) may extend left and right. The second support member (422) and the fourth support member (424) may extend up and down and may be located between the first support member (421) and the third support member (423).

[0093] The third type of support member (430) may include a plurality of sub-support members (431 to 434). More specifically, the third type of support member (430) may include a first support member (431), a second support member (432), a third support member (433), and a fourth support member (434). The second support member (432) and the fourth support member (434) may extend vertically. The first support member (431) and the third support member (433) may extend horizontally. The first support member (431) and the third support member (433) may be located between the second support member (432) and the fourth support member (434).

[0094] The fourth type of support member (440) may be of a free shape. The fourth type of support member (440) may be of a shape optimized to best protect the components included in the detector (100). The fourth type of support member (440) can protect the components included in the detector (100) from external forces while preventing the detector (100) from twisting or denting. In particular, the detector (100) of the present disclosure has the effect of preventing the detection panel from breaking due to external forces. In addition, the detector (100) including the fourth type of support member (440) of the present disclosure has the effect of achieving slimming and miniaturization of the detector (100) by optimizing the arrangement of components.

[0095] The fourth type of support member (440) may include a plurality of sub-support members (441 to 444). More specifically, the fourth type of support member (440) may include a first support member (441), a second support member (442), a third support member (443), and a fourth support member (444). The second support member (442) and the fourth support member (444) may extend vertically. The first support member (441) and the third support member (443) may extend horizontally. The second support member (442) may be positioned between the first support member (441) and the third support member (443). Additionally, the fourth support member (434) may extend from the right side of the first support member (441) to the top of the third support member.

[0096] The support member (230) may include a plurality of support members. That is, the support member (230) may function as a support member (230) by including four independent sub-support members, such as one of the second type of support member (420), the third type of support member (430), and the fourth type of support member (440). Unlike FIG. 4, the support member (230) may be implemented with two independent sub-support members, three independent sub-support members, or four or more independent sub-support members. As the number of sub-support members increases, the necessary areas can be reinforced, thus having the effect of increasing the rigidity of the detector (100). In addition, as the number of sub-support members decreases, the assemblability of the detector (100) increases.

[0097] Referring again to FIG. 3, a position for a support member (230) may be formed in the middle plate (210). For example, the middle plate (210) may include a first support member coupling part (310), a second support member coupling part (320), a third support member coupling part (330), and a fourth support member coupling part (340). The middle plate (210) may be provided with a screw coupling hole for coupling a screw penetrating the support member (230). A screw hole (350) may be formed in at least one of the first support member coupling part (310), the second support member coupling part (320), the third support member coupling part (330), and the fourth support member coupling part (340).

[0098] At least one of the first support member connecting part (310), the second support member connecting part (320), the third support member connecting part (330), and the fourth support member connecting part (340) can be firmly connected to the support member (230) with a screw. For example, the first support member connecting part (310), the second support member connecting part (320), and the fourth support member connecting part (340) can be firmly connected to the first support member, the second support member, and the fourth support member with a screw. In addition, the third support member connecting part (330) and the third support member can be connected by an adhesive layer.

[0099] A groove may be formed in at least one of the first support member coupling part (310), the second support member coupling part (320), the third support member coupling part (330), and the fourth support member coupling part (340), and the support member (230) may be inserted into the groove and coupled. Accordingly, the support member (230) and the middle plate (210) can be firmly coupled, and assembly ease can be increased.

[0100] FIG. 5 is a rear view of a middle plate and a support member according to one embodiment of the present disclosure.

[0101] Referring to FIG. 5, the middle plate (210) and the support member (230) may be joined by an adhesive layer. The first support member (610) may be joined to the middle plate (210) by the first adhesive layer (510). Additionally, the second support member (620) may be joined to the middle plate (210) by the second adhesive layer (520). The third support member (630) may be joined to the middle plate (210) by the third adhesive layer (530). The fourth support member (640) may be joined to the middle plate (210) by the fourth adhesive layer (540). The first adhesive layer (510) to the fourth adhesive layer (540) may be located on the same plane. However, they are not limited thereto.

[0102] FIG. 6 is a drawing for explaining a support member according to one embodiment of the present disclosure. FIG. 7 is also a drawing for explaining a support member according to one embodiment of the present disclosure.

[0103] FIGS. 6 and FIGS. 7 are perspective views of a support member according to one embodiment of the present disclosure, viewed from the rear. FIG. 7 shows the support member (230) viewed from a different angle from FIG. 6 to show the curvature of the support member (230) in more detail.

[0104] The support member (230) may include a first support member (610), a second support member (620), a third support member (630), and a fourth support member (640). A plurality of holes may be formed in the support member (230) to reduce weight. Additionally, the plurality of holes formed in the support member (230) allow air to flow freely, thereby enabling efficient cooling of the detector (100). Furthermore, the support member (230) is made of a material with high thermal conductivity, allowing heat to spread effectively. Thus, the heat-sensitive detection panel (110) can generate high-quality radiation images. Additionally, the support member (230) has the effect of preventing distortion of the detector (100) and protecting the detector (100) from external impact. In particular, it has the effect of preventing the detection panel included in the detector (100) from being damaged by external force.

[0105] Additionally, the support member (230) has a screw hole (650) formed therein, so that the screw passes through the screw hole (650) of the support member (230) and is fixed to the screw hole (350) of the middle plate (210), thereby allowing the support member (230) and the middle plate (210) to be fixed.

[0106] The support member (230) of FIG. 6 may have the same shape as the support member (440) of the fourth form of FIG. 4.

[0107] The support member (230) may include at least one connecting surface and an inclined surface. The connecting surface may include at least two of the first connecting surface (811) to the sixth connecting surface (915). Additionally, the inclined surface may include at least two of the first inclined surface (812) to the fourth inclined surface (914).

[0108] A plurality of holes may be formed in at least one of the connecting surface or the inclined surface. For example, a plurality of holes may be formed in at least one of the second connecting surface (813) and the third connecting surface (815). A plurality of holes may be formed in the second connecting surface (813) of the first supporting member (610), the second supporting member (620), and the fourth supporting member (640). Additionally, a plurality of holes may be formed in the third connecting surface (815) of the third supporting member (630). The extension direction of the plurality of holes may be perpendicular to the extension direction of the supporting member. For example, the extension direction of the first supporting member (610) may be the second direction. That is, the length of the second direction of the first supporting member (610) may be longer than the length of the first direction. The second direction may be, for example, the left. The extension direction of a plurality of holes formed on the second connecting surface (813) of the first support member (610) may be a first direction perpendicular to the second direction. That is, the length of the first direction of one of the plurality of holes may be longer than the length of the second direction. The first direction may be, for example, an upward direction.

[0109] A plurality of holes formed in the second connecting surface (813) may have a rectangle in which the length of the first or second direction is longer than the length of the second or first direction, and a plurality of holes formed in the third connecting surface (815) may have a square. The size of one of the plurality of holes formed in the second connecting surface (813) may be larger than the size of one of the plurality of holes formed in the third connecting surface (815). The reason the shape and size of the plurality of holes formed in the second connecting surface (813) and the third connecting surface (815) are different may be due to differences in components and functions located near the second connecting surface (813) or the third connecting surface (815). The third connecting surface (815) may be located at the edge of the detector (100) rather than the second connecting surface (813). Since the third connecting surface (815) is located at the edge of the detector (100), it may need to have greater rigidity. Therefore, the size of the hole formed in the third connecting surface (815) may be small. Also, the second connecting surface (813) may be closer to the control board, power board, or battery (1030), etc. than the third connecting surface (815). In order to effectively dissipate heat generated from the control board, power board, or battery (1030) to the outside, the hole formed in the second connecting surface (813) may be larger than the hole formed in the third connecting surface (815) to facilitate airflow.

[0110] The first support member (610) extends in a second direction and may be located in the first direction portion of the middle plate. In the present disclosure, the second direction may mean left. However, it is not limited thereto, and the second direction may mean right. Also, the first direction may mean upward. However, it is not limited thereto, and the first direction may mean downward.

[0111] The first support member extends to the left and can be located in the upper part of the middle plate.

[0112] The second support member (620) may extend in the opposite direction of the first direction from at least a portion of the side opposite to the first direction of the first support member (610). Additionally, the second support member (620) may be located in the second direction portion of the middle plate (210).

[0113] The second support member extends downward from at least a portion of the downward side of the first support member and may be located in the left portion of the middle plate.

[0114] The third support member (630) may extend in the opposite direction of the second direction from at least a portion of the side opposite to the first direction of the second support member (620). The third support member (630) may be located in the portion opposite to the first direction of the middle plate (210).

[0115] The third support member extends to the right from at least a portion of the downward side of the second support member and may be located in the downward portion of the middle plate.

[0116] The fourth support member (640) may extend in the first direction from at least a portion of the first direction side of the third support member (630) to at least a portion of the second direction opposite side of the first support member (610). The fourth support member (640) may be located in the second direction opposite portion of the middle plate (210).

[0117] The fourth support member extends upward from at least a portion of the upward side of the third support member to at least a portion of the right side of the first support member, and may be located in the right side portion of the middle plate.

[0118] FIG. 8 shows a cross-section of a detector according to one embodiment of the present disclosure. FIG. 9 shows a cross-section of a detector according to one embodiment of the present disclosure.

[0119] FIG. 8 shows a cross-section of a support member (230) having a partial trapezoidal shape. FIG. 9 also shows a cross-section of a support member (230) having a partial inverted trapezoidal shape.

[0120] Referring to FIG. 8 together with FIG. 2 below, at least a portion of the support member (230) may include at least one of a first connecting surface (811), a first inclined surface (812), a second connecting surface (813), a second inclined surface (814), and a third connecting surface (815). At least one of the first connecting surface (811), the first inclined surface (812), the second connecting surface (813), the second inclined surface (814), and the third connecting surface (815) may be formed on at least a portion of one of the first support member (610), the second support member (620), the third support member (630), and the fourth support member (640). The first support member (610), the second support member (620), the third support member (630), and the fourth support member (640) all include a first connecting surface (811), a first inclined surface (812), a second connecting surface (813), a second inclined surface (814), and a third connecting surface (815), but the first connecting surface (811), the first inclined surface (812), the second connecting surface (813), the second inclined surface (814), and the third connecting surface (815) may be formed only in a part of one of the first support member (610), the second support member (620), the third support member (630), and the fourth support member (640). For example, the first connecting surface (811) may be formed only in a portion of the longitudinal direction of the first supporting member (610).

[0121] The first connecting surface (811) is connected to the rear surface (123) of the housing (120) and may be parallel to the rear surface (123) of the housing (120). The first connecting surface (811) may be joined to the rear surface (123) of the housing (120) by adhesive or screws. However, it is not limited thereto, and the first connecting surface (811) may be in contact with or connected to the middle plate (210). The first connecting surface (811) may be connected to at least one of the rear surface (123) and the middle plate (210). By connecting the first connecting surface (811) to the rear surface (123) and the middle plate (210), the detector (100) may be made more robust. Alternatively, the first connecting surface (811) may be connected to either the rear surface (123) or the middle plate (210) so that the transmission of external force to the detector (100) is blocked.

[0122] The first inclined surface (812) is connected to the first connecting surface (811) and may have a predetermined angle of inclination with the rear surface (123). For example, the predetermined angle of inclination may be 40 degrees or more and 50 degrees or less. As the first inclined surface (812) is more parallel to the first connecting surface (811), the effect of protecting the internal components of the detector (100) from external forces or preventing the distortion of the detector (100) may be reduced. Additionally, as the first inclined surface (812) is more perpendicular to the first connecting surface (811), the distance the radiation penetrates through the first inclined surface (812) is longer, so the first inclined surface (812) may appear in the radiation image. That is, the quality of the radiation projection may be reduced. In particular, when the support member (230) is made of a material with low radiation permeability, back scattering may occur due to the distance the radiation penetrates the support member (230). That is, the shape of the support member (230) appears in the image. However, when using a support member (230) with a trapezoidal or inverted trapezoidal shape formed by the first connecting surface (811), the first inclined surface (812), the second connecting surface (813), the second inclined surface (814), or the third connecting surface (815), the back scattering phenomenon can be minimized. This is because the distance the radiation penetrates the support member (230) becomes almost the same across the entire area of ​​the detector (100).

[0123] In addition, since a bent portion is created in the support member (230) by the first inclined surface (812) and the second inclined surface (814), the rigidity is increased, and even if the length of the support member (230) is reduced, high rigidity can be secured, so the effect of achieving lightweighting is achieved.

[0124] When the predetermined angle of inclination is 40 degrees or more and 50 degrees or less, the support member (230) can protect the internal components of the detector (100) and prevent distortion while minimizing the effect on the radiation image. The first inclined surface (812) may have a thickness thinner than at least one of the first connecting surface (811), the second connecting surface (813), and the third connecting surface (815). Additionally, a radiation-transparent material is used in the support member (230) to have the effect of minimizing the effect of the first inclined surface (812) on the image.

[0125] Of course, when the support member (230) is implemented using a material with high radiation transparency, such back scattering phenomenon does not occur, so the angle of inclination can be 10 degrees or more and 90 degrees or less.

[0126] The second connecting surface (813) is connected to the first inclined surface (812), connected to the middle plate (210), and may be parallel to the middle plate (210). The second connecting surface (813) may be joined to the back surface of the middle plate (210) by adhesive or screw. However, it is not limited thereto, and the second connecting surface (813) may be in contact with or connected to the rear surface (123). The second connecting surface (813) may be connected to at least one of the rear surface (123) and the middle plate (210).

[0127] A plurality of holes are drilled in the second connecting surface (813) so that the air inside the detector (100) can circulate smoothly and the inside of the detector (100) can be cooled by the airflow. Accordingly, the detection panel (110) can acquire radiation images without being affected by heat, and thus the detector (100) has the effect of acquiring high-quality radiation images.

[0128] The width (641) of the second connecting surface (813) may be greater than or equal to the width of at least one of the first connecting surface (811), the first inclined surface (812), the second inclined surface (814), and the third connecting surface (815). Here, the width may represent the length in the direction from the center of the detector (100) toward the edge. In particular, the width of the second connecting surface (813) of the first supporting member (610), the second supporting member (620), and the fourth supporting member (640) may be greater than or equal to the width of at least one of the first connecting surface (811), the first inclined surface (812), the second inclined surface (814), and the third connecting surface (815). However, it is not limited thereto. The width of the second connecting surface (813) of the third support member (630) may be smaller than the width of at least one of the first connecting surface (811), the first inclined surface (812), the second inclined surface (814), and the third connecting surface (815). Additionally, the width of the third connecting surface (710) of the third support member (630) may be greater than or equal to the width of the first connecting surface or the second connecting surface of the third support member (630).

[0129] The width of at least one second connecting surface (813) among the first support member (610), the second support member (620), the third support member (630), and the fourth support member (640) may not be constant. For example, the width of the first support member (610) may have a long width (611) and a short width (612). Additionally, the width of the second support member (620) may have a long width (621) and a short width (622).

[0130] Various components may be located on the back of the second connecting surface (813). For example, components such as a control board may be located on the back of the second connecting surface (813) to minimize distortion and reduce the defect rate. Additionally, the control board may be protected from external impact by the second connecting surface (813).

[0131] The second inclined surface (814) is connected to the second connecting surface (813) and may have a predetermined angle of inclination with the rear surface (123) of the housing (120). The second inclined surface (814) may not be parallel to the first inclined surface (812). For example, the predetermined angle of inclination may be 40 degrees or more and 50 degrees or less. When the predetermined angle of inclination is 40 degrees or more and 50 degrees or less, the support member (230) can protect the internal components of the detector (100) and prevent distortion while minimizing the effect on the radiation image. The second inclined surface (814) may have a thinner thickness than at least one of the first connecting surface (811), the second connecting surface (813), and the third connecting surface (815). In addition, a radiation-transmitting material is used in the support member (230), so that the effect of the second inclined surface (814) on the image can be minimized.

[0132] The first inclined surface (812) and the second inclined surface (814) may not be parallel. The first inclined surface (812) and the second inclined surface (814) may have a predetermined angle with respect to the rear surface (123) of the middle plate (210) or the housing (120). Among the parts of the trapezoidal shape formed by the cross-section of the support member (230), the first inclined surface (812) and the second inclined surface (814) may correspond to the sides of the trapezoid.

[0133] The third connecting surface (815) is connected to the second inclined surface (814) and may be connected to the rear surface (123) of the housing (120). The third connecting surface (815) may be parallel to the rear surface (123). However, it is not limited thereto, and the third connecting surface (815) may be in contact with or connected to the middle plate (210). The third connecting surface (815) may be connected to at least one of the rear surface (123) and the middle plate (210).

[0134] In FIG. 2, the third connecting surface (815) may extend in the opposite direction to the second direction, and in FIG. 8, the third connecting surface (815) may extend in the second direction. At least one of the first supporting member (610), the second supporting member (620), the third supporting member (630), and the fourth supporting member (640) may have at least one of the shape of the third connecting surface (815) of FIG. 2 and the shape of the third connecting surface (815) of FIG. 8. For example, referring to FIG. 6, the upper part of the second supporting member (620) has the shape of the third connecting surface (815) of FIG. 2, and the lower part of the second supporting member (620) has the shape of the third connecting surface (815) of FIG. 8.

[0135] The third connecting surface (815) may be located at the edge of the detector (100) rather than the first connecting surface (811) or the second connecting surface (813). At least one of the first supporting member (610), the second supporting member (620), the third supporting member (630), and the fourth supporting member (640) may include a plurality of holes. The plurality of holes may allow air inside the detector (100) to circulate smoothly and may allow cooling of the inside of the detector (100) by the flow of air. For example, the third connecting surface (710) of the third supporting member (630) of FIG. 7 may include a plurality of holes. The shape of the plurality of holes formed on the third connecting surface (710) of the third supporting member (630) may be nearly square. The shape of the plurality of holes formed on the second connecting surface (813) of the first support member (610), the second support member (620), and the fourth support member (640) may be rectangular and may be larger than the size of the holes in the third support member (630). Although the width of the third support member (630) is smaller than or equal to that of the first support member (610), the second support member (620), and the fourth support member (640), the plurality of holes formed in the third support member (630) are relatively small, so the strength of the third support member (630) may be almost the same as that of the other support members. In addition, the support member (230) can be made lighter and the cooling efficiency can be increased through the plurality of holes.

[0136] The width of the third connecting surface (710) of the third support member (630) may be greater than or equal to the width of the first connecting surface or the second connecting surface of the third support member (630). The third support member (630) may have a larger surface that contacts the rear surface (123).

[0137] The first support member (610), the second support member (620), the third support member (630), and the fourth support member (640) have a shape as shown in FIG. 8, thereby minimizing distortion of the detector (100) and protecting the internal configuration of the detector (100) from external forces. Additionally, the internal space of the detector (100) can be efficiently utilized by the support member (230) as shown in FIG. 8, allowing the detector (100) to be thin and the bezel to be minimized. In other words, the detector (100) can be made smaller and lighter.

[0138] At least two of the rear surface (123), the first inclined surface (812), the second connecting surface (813), and the second inclined surface (814) can form a first space (820). The first space (820) may correspond to a concave portion (231). The detector (100) may include a filler located in the first space (820). However, the filler may also be located in a space other than the first space (820). Since the filler has already been described above, a redundant description is omitted.

[0139] The interior of the detector (100) may further include a second space (831) and a third space (832). The second space (831) may be a space formed by at least two of a middle plate (210), a first connecting surface (811), a rear surface (123), and a first inclined surface (812). Additionally, the third space (832) may be a space formed by at least two of a middle plate (210), a second inclined surface (814), a rear surface (123), and a third connecting surface (815). The detector (100) may further include a filler material in at least one of the second space (831) and the third space (832).

[0140] Components of the detector (100) may be located in at least one of the first space (820), the second space (831), and the third space (832). For example, at least one of the first space (820), the second space (831), and the third space (832) may include at least one of a coil (1010), a power board (1020), a battery (1030), and a control board (1040). The support member (230) can increase the rigidity of the detector (100) to prevent the detector (100) from twisting, while ensuring that the various components included in the detector (100) are not affected by external forces.

[0141] As previously explained, FIG. 9 shows an inverted trapezoidal support member (230).

[0142] Referring to FIG. 9, at least a portion of the support member (230) may include at least one of a fourth connecting surface (911), a third inclined surface (912), a fifth connecting surface (913), a fourth inclined surface (914), and a sixth connecting surface (915). At least one of the fourth connecting surface (911), the third inclined surface (912), the fifth connecting surface (913), the fourth inclined surface (914), and the sixth connecting surface (915) may be formed on at least a portion of one of the first support member (610), the second support member (620), the third support member (630), and the fourth support member (640). The first support member (610), the second support member (620), the third support member (630), and the fourth support member (640) all include a fourth connecting surface (911), a third inclined surface (912), a fifth connecting surface (913), a fourth inclined surface (914), and a sixth connecting surface (915), but the fourth connecting surface (911), the third inclined surface (912), the fifth connecting surface (913), the fourth inclined surface (914), and the sixth connecting surface (915) may be formed only in a part of one of the first support member (610), the second support member (620), the third support member (630), and the fourth support member (640). For example, the fourth connecting surface (911) may be formed only in a portion of the longitudinal direction of the first supporting member (610).

[0143] The fourth connecting surface (911) is connected to the middle plate (210) and may be parallel to the middle plate (210). However, it is not limited to this, and the fourth connecting surface (911) may be in contact with or connected to the rear surface (123). If the configuration connected to the rear surface (123) is modified to be connected to the middle plate (210), the description of the first connecting surface (811) can be applied to the fourth connecting surface (911).

[0144] The third inclined surface (912) is connected to the fourth connecting surface (911) and may have a predetermined angle of inclination with the middle plate (210). The description of the first inclined surface (812) may be applied to the third inclined surface (912).

[0145] The fifth connecting surface (913) is connected to the third inclined surface (912), connected to the rear surface (123) of the housing (120), and may be parallel to the rear surface (123). However, it is not limited to this, and the fifth connecting surface (913) may be in contact with or connected to the middle plate (210). If the configuration connected to the middle plate (210) is modified to be connected to the rear surface (123), the description of the second connecting surface (813) can be applied to the fifth connecting surface (913).

[0146] The fourth inclined surface (914) is connected to the fifth connecting surface (913) and has a predetermined angle of inclination with the middle plate (210), and may not be parallel to the third inclined surface (912). The description of the second inclined surface (814) may be applied to the fourth inclined surface (914).

[0147] The sixth connecting surface (915) is connected to the fourth inclined surface (914), connected to the middle plate (210), and may be parallel to the middle plate (210). However, it is not limited to this, and the sixth connecting surface (915) may be in contact with or connected to the rear surface (123). If the configuration connected to the rear surface (123) is modified to be connected to the middle plate (210), the description of the third connecting surface (815) can be applied to the sixth connecting surface (915).

[0148] At least two of the middle plate (210), the third inclined surface (912), the fifth connecting surface (913), and the fourth inclined surface (914) can form a fourth space (920). The fourth space (920) may correspond to a concave portion (231). The detector (100) may include a filler located in the fourth space (920). However, the filler may also be located in a space other than the fourth space (920). Since the filler has already been described above, a redundant description is omitted.

[0149] The interior of the detector (100) may further include a fifth space (931) and a sixth space (932). The fifth space (931) may be a space formed by at least two of the middle plate (210), the fourth connecting surface (911), the rear surface (123), and the third inclined surface (912). The sixth space (932) may be a space formed by at least two of the middle plate (210), the fourth inclined surface (914), the rear surface (123), and the sixth connecting surface (915). The detector (100) may further include a filler material in at least one of the fifth space (931) and the sixth space (932).

[0150] FIG. 10 may be a drawing for explaining a configuration included in a detector according to one embodiment of the present disclosure.

[0151] FIG. 10 is a view of the detector (100) from behind.

[0152] The detector (100) may include a receiving coil (1010) for wireless charging. The receiving coil (1010) may correspond to the coil (1010). Energy can be received from the outside by the receiving coil (1010) to charge the battery (1030).

[0153] The detector (100) may include a power board (1020). The power board (1020) may convert energy received from the receiving coil (1010) into electrical energy for charging the battery (1030), or convert energy from the battery (1030) into electrical energy for consuming the detector (100).

[0154] The battery (1030) of the detector (100) may be detachable. However, it is not limited to this.

[0155] The battery (1030) may be located in a place where the support member (230) is not formed. That is, the detector (100) may include the battery (1030) in a region of the middle plate where the support member is not formed. The thickness of the cell included in the battery (1030) may be smaller than or equal to the thickness of the support member (230). However, it is not limited thereto, and the thickness of the cell included in the battery (1030) may be greater than the thickness of the support member (230). In addition, the support member (230) may have a shape that wraps around the battery (1030) on the plane formed by the first direction and the second direction.

[0156] A space for a battery may be formed in the area of ​​the middle plate where a support member is not formed. The size of the sum of the area of ​​the support member and the area of ​​the battery may be smaller than or equal to the size of the area of ​​the middle plate. The area of ​​the middle plate excluding the area of ​​the support member and the area of ​​the battery may be referred to as the remaining area. The remaining area may be a space where screw holes are formed for joining between components, a space for electronic components, or a space for circulating air. In the present disclosure, at least one of the area of ​​the middle plate, the area of ​​the support member, and the area of ​​the battery may refer to an area on the plane formed by the first direction and the second direction. When an external impact is applied, the support member (230) absorbs the impact, and the impact may not be transmitted to the battery (1030).

[0157] For example, the battery (1030) may be located between the space formed by the first support member (610), the second support member (620), the third support member (630), and the fourth support member (640). That is, the first support member (610) may be located on the upper side of the battery (1030), the second support member (620) on the left side, the third support member (630) on the lower side, and the fourth support member (640) on the right side. Since all sides of the battery (1030) are protected by the support members (230), the battery (1030) may be almost unaffected by external impact. Therefore, the detector (100) of the present disclosure may be very safe.

[0158] The detector (100) may include a control board (1040). The control board (1040) may include at least one of a control unit, a communication unit, an input unit, and an output unit.

[0159] As previously explained, a filler material (1050) may be positioned in the concave portion included in the support member (230). The filler material (1050) may serve to fill the empty space inside the detector. The hole formed in the support member (230) may be a space formed to allow the filler material (1050) to be firmly attached to the support member (230). The filler material (1050) not only absorbs external force, but also ensures that the internal components of the detector (100) always remain in the same position relative to each other even when an external force is applied to the detector (100), thereby increasing the durability of the detector (100).

[0160] FIG. 11 is a drawing for explaining a radiation detection panel according to one embodiment of the present disclosure.

[0161] The radiation detection panel (110) of the present disclosure may include a front scintillator (3110), a TFT panel (3120), and a rear scintillator (3130).

[0162] The front scintillator (3110) may be configured to receive radiation and emit it as visible light. The TFT panel (3120) may be configured to be located behind the front scintillator (3110). The rear scintillator (3130) may be located behind the TFT panel (3120).

[0163] FIG. 12 is a drawing for explaining the radiation detection panel of the present disclosure in more detail.

[0164] FIG. 12 is according to one embodiment of the present disclosure, and the radiation detection panel may use various scintillators and TFTs different from FIG. 12.

[0165] The front scintillator (3110) may include a support layer (3211) and a light conversion layer (3212). The support layer (3211) may be located on the front of the light conversion layer (3212). The support layer (3211) may be configured to protect the surface of the light conversion layer (3212). Additionally, the support layer (3211) may be configured to maintain the shape of the light conversion layer (3212). The light conversion layer (3212) may include GADOX. That is, the front scintillator (3110) may be a Gadox sheet comprising the support layer (3211) and the light conversion layer (3212).

[0166] The TFT panel (3120) may include a pixel array (3221) and a panel supporting layer (3222). The pixel array (3221) may include an a-Si (Amorphous Silicon) array. The panel supporting layer (3222) may include a PI (polyimide) layer. The panel supporting layer (3222) may include a substrate with high heat resistance, such as a semiconductor substrate, a quartz substrate, and a glass substrate. Additionally, the panel supporting layer (3222) may include a flexible substrate such as plastic, aramid, or bio-nanofiber.

[0167] The TFT panel (3120) can be bonded by a front scintillator (3110) and an adhesive film (3240). Additionally, the TFT panel (3120) can be bonded by a rear scintillator (3130) and an adhesive film (3250).

[0168] The rear scintillator (3130) may include a support layer (3231) and a light conversion layer (3232). The support layer (3231) may be located on the rear side of the light conversion layer (3232). The support layer (3231) may be configured to protect the surface of the light conversion layer (3232). The support layer (3231) may also be configured to maintain the shape of the light conversion layer (3232). The light conversion layer (3232) may include GADOX. That is, the rear scintillator (3130) may be a Gadox sheet comprising the support layer (3231) and the light conversion layer (3232).

[0169] By positioning the support layer (3211) on the front of the radiation detection panel and the support layer (3231) on the rear of the radiation detection panel, the front and rear of the radiation detection panel can be protected. Additionally, by positioning the light conversion layer (3212) on the front of the TFT panel (3120) and the light conversion layer (3232) on the rear of the TFT panel (3120), the distance between the light conversion layers (3212, 3232) and the TFT panel (3120) can be minimized. The light conversion layers (3212, 3232) can emit visible light based on the received radiation. The TFT panel (3120) can receive the visible light and generate an electrical signal. The radiation detector can acquire a radiation image based on the electrical signal.

[0170] FIG. 13 is a drawing for explaining a scintillator according to one embodiment of the present disclosure.

[0171] As previously explained, at least one of the front scintillator and the back scintillator may be a gadox sheet. In this case, the density of the gadox crystals in the front scintillator may differ from the density of the gadox crystals in the back scintillator. However, this is not limited to this, and the density of the gadox crystals in the front scintillator may be independent of the density of the gadox crystals in the back scintillator. That is, the density of the gadox crystals in the front scintillator may not affect the density of the gadox crystals in the back scintillator. The density of the gadox crystals in the front scintillator can be determined regardless of the density of the gadox crystals in the back scintillator. In other words, the density of the gadox crystals in the front scintillator may be the same as or different from the density of the gadox crystals in the back scintillator.

[0172] For example, the density of the Gadox crystals in the front scintillator may be lower than the density of the Gadox crystals in the back scintillator. The density of the Gadox crystals in the front scintillator may be equal to the density of the Gadox crystals in the back scintillator. The density of the Gadox crystals in the front scintillator may be equal to or lower than the density of the Gadox crystals in the back scintillator. However, it is not limited to this. The density of the Gadox crystals in the front scintillator may be greater than the density of the Gadox crystals in the back scintillator.

[0173] The light conversion layer (3212) of the front scintillator (3110) and the light conversion layer (3232) of the rear scintillator (3130) may include Gadox crystals. The characteristics of the front scintillator (3110) and the rear scintillator (3130) may vary based on the density and thickness of the Gadox crystals in the light conversion layer (3212) and the light conversion layer (3232). The crystal density of the Gadox may refer to the density of the Gadox crystals included in the light conversion layers (3212, 3232).

[0174] A low density of the Gadox crystal means that the number of Gadox crystals per unit area that respond to radiation is small. Therefore, the low-density Gadox crystals included in the scintillator (3310) will generate relatively little visible light. When using low-density Gadox crystals, a high-sharpness image can be obtained. This is because the visible light received by a single pixel of the TFT panel (3320) is likely to be visible light generated from a single Gadox crystal. In other words, when the radiation detector uses low-density Gadox crystals, an image with a high MTF (modulation transfer function), low sensitivity, and low noise can be obtained. Therefore, when the radiation detector uses low-density Gadox crystals, it can obtain an image with high sharpness of the subject compared to when using high-density Gadox crystals.

[0175] A high density of Gadox crystals means that there are many Gadox crystals per unit area that respond to radiation. Therefore, high-density Gadox crystals included in the scintillator (3330) will generate a relatively large amount of visible light. Since high-density Gadox crystals generate a large amount of light even with a small amount of radiation, the radiation detector can obtain a highly sensitive image. However, when the radiation detector uses high-density Gadox crystals, it can obtain an image with lower sharpness than when using low-density Gadox crystals. This is because a single pixel of the TFT panel (3340) will receive visible light generated from multiple Gadox crystals. In other words, a radiation detector containing high-density Gadox crystals can obtain an image with low MTF, high sensitivity, and a lot of noise. When the radiation detector uses high-density Gadox crystals, it can obtain an image with high sensitivity to radiation compared to when using low-density Gadox crystals.

[0176] Referring again to FIG. 12, radiation passes through a low-density front scintillator (3110) and a TFT panel (3120) and then reaches a high-density rear scintillator (3130). Since the relatively high-density rear scintillator (3130) reacts in the direction of the TFT panel (3120), the closer it is to the TFT panel (3120), the higher the sensitivity of the radiation detector can obtain an image.

[0177] By including a front scintillator (3110), a TFT panel (3120), and a rear scintillator (3130), the radiation detector can acquire an image by reflecting the characteristics of light conversion layers (3212, 3232) containing gadox crystals of different densities. Through this, the disadvantages of light conversion layers (3212, 3232) of different densities are compensated for, and the radiation detector can acquire an improved radiation image.

[0178] As previously explained, at least one of the front scintillator and the rear scintillator is a gadox sheet, and the thickness of the front scintillator (3110) may differ from the thickness of the rear scintillator (3130). However, this is not limited thereto, and the thickness of the front scintillator (3110) may be independent of the thickness of the rear scintillator (3130). The thickness of the front scintillator (3110) may not affect the thickness of the rear scintillator (3130). The thickness of the front scintillator (3110) may be determined regardless of the thickness of the rear scintillator (3130). That is, the thickness of the front scintillator (3110) may be the same as or different from the thickness of the rear scintillator (3130).

[0179] For example, the thickness of the front scintillator (3110) may be thinner than or equal to the thickness of the rear scintillator (3130). Alternatively, the thickness of the front scintillator (3110) may be thinner than the thickness of the rear scintillator (3130). The thickness of the front scintillator (3110) may be equal to the thickness of the rear scintillator (3130). However, it is not limited to this, and the thickness of the front scintillator (3110) may be thicker than the thickness of the rear scintillator (3130).

[0180] If the thickness of the light conversion layer (3212) of the front scintillator (3110) is thinner than the thickness of the light conversion layer (3232) of the rear scintillator (3130), image quality and sensitivity may be improved. Additionally, if the area of ​​the light conversion layer (3212) of the front scintillator (3110) is smaller than the area of ​​the light conversion layer (3232) of the rear scintillator (3130), image quality and sensitivity may be improved. A radiation detector using both the front scintillator (3110) and the rear scintillator (3130) may have improved spatial resolution and higher dose efficiency than a radiation detector using only one of them. Furthermore, the sharpness of the image may also be improved as a result. By including a front scintillator (3110), a TFT panel (3120), and a rear scintillator (3130), the radiation detector can acquire an image by reflecting the characteristics of the light conversion layers (3212, 3232) with different thicknesses or areas. By compensating for the disadvantages of the light conversion layers (3212, 3232) with different thicknesses or areas, the radiation detector can acquire an improved radiation image.

[0181] As previously explained, at least one of the front scintillator and the back scintillator may be a gadox sheet. Additionally, the front scintillator may have a material capable of acquiring images with a higher modulation transfer function (MTF), lower sensitivity, and lower noise than the back scintillator. As previously explained, by adjusting at least one of the density, thickness, and area of ​​the front scintillator and the back scintillator, the front scintillator can be made to have a higher modulation transfer function (MTF), lower sensitivity, and lower noise than the back scintillator. However, this is not limited to this, and various methods can be used to make the front scintillator have a higher modulation transfer function (MTF), lower sensitivity, and lower noise than the back scintillator.

[0182] The above describes the case where both the front scintillator and the back scintillator include a Gadox sheet. Gadox is a light conversion layer with high sensitivity to high-energy radiation, and when both the front scintillator and the back scintillator include a Gadox sheet, the sensitivity may be higher than when there is only one scintillator. Therefore, the radiation detector can acquire a clear image.

[0183] However, it is not limited to this. One of the front and rear scintillators may be a gadox sheet, and the other may be either cesium iodide (CsI) or perovskite. In this way, even if only one side is a gadox sheet, the radiation detector can take advantage of both the benefits of the gadox sheet and the benefits of non-gadox materials.

[0184] The radiation detector of the present disclosure may be a bendable detector comprising a flexible TFT. Additionally, as described above, the radiation detector may include a front scintillator and a back scintillator comprising a gadox sheet. When the front scintillator and the back scintillator comprise a gadox sheet, there are advantages over using scintillators made of other materials in the following respects. High-energy industrial radiation sources can create high afterimages within CsI. Therefore, a radiation detector comprising a scintillator made of CsI material may acquire an image with afterimages (noise), resulting in an unclear image. Conversely, a radiation detector comprising a front scintillator and a back scintillator comprising a gadox sheet can acquire a clear image.

[0185] In addition, scintillators containing CsI may have their columnar structure destroyed during repeated bending. If the columnar structure is destroyed, the efficiency of converting radiation into visible light decreases, which may result in a decrease in image quality. However, radiation detectors containing a front scintillator and a back scintillator containing a gadox sheet can always obtain a clear image even when bending is performed multiple times.

[0186] Therefore, in the case of a radiation detector in which a scintillator containing CsI and a scintillator containing a Gadox sheet are used together, the rear scintillator may contain CsI, and the front scintillator may contain the Gadox sheet. This is because the curvature of the rear scintillator will be relatively smaller. Additionally, since the radiation reaches the rear scintillator after passing through the front scintillator and the TFT panel, significant afterimages will not remain. However, this is not the only case.

[0187] Although the sensitivity of a Gadox sheet may be lower than that of a CsI material, the radiation detector of the present disclosure can increase sensitivity by placing the Gadox sheet in a double arrangement on the front and back surfaces. Therefore, according to the radiation detector of the present disclosure, it may have the same effect as using a high-sensitivity photoconversion layer.

[0188] Furthermore, in the case of high-energy X-rays and gamma rays used in industrial radiation detectors, the dose absorbed by the scintillator may be small. This causes the imaging time to be prolonged. However, since the radiation detector of the present disclosure uses a dual optical conversion layer structure, it has high sensitivity and can reduce imaging time. This has the effect of lowering the exposure of the subject or user.

[0189] In addition, to increase only the sensitivity in the dual optical conversion layer, high-density or thick Gadox sheets can be used in a double layer on both the front and back. However, in this case, the image sharpness may decrease. Therefore, to increase image sharpness, using low-density or thin Gadox sheets in a double layer can increase sensitivity while maintaining sharpness. In other words, efficiency can be improved by applying the thickness or density of the Gadox according to the application of the radiation detector, regardless of the front or back of the radiation detection panel. For example, the front scintillator and the back scintillator may have the same thin thickness or the same density of Gadox crystals. However, they are not limited to this.

[0190] FIG. 14 is a drawing for explaining a radiation detector according to one embodiment of the present disclosure. FIG. 15 is a drawing for explaining a radiation detector according to one embodiment of the present disclosure. FIG. 16 is a drawing for explaining a radiation detector according to one embodiment of the present disclosure.

[0191] Referring to FIG. 14, the radiation detector may further include a corner protection part (1410) and a corner bracket (1420). The corner protection part (1410) and the corner bracket (1420) may be located at the corners of the housing (120). The corner protection part (1410) and the corner bracket (1420) may be located at least one of the four corners of the housing (120). The corner protection part (1410) and the corner bracket (1420) may be located at least one of the upper-left corner, lower-left corner, lower-right corner, or upper-right corner of the housing (120). However, it is not limited thereto, and the corner protection part (1410) and the corner bracket (1420) may be located on the side of the housing (120). The corner protection part (1410) and the corner bracket (1420) may be located on at least one of the four sides of the housing (120). The corner protection part (1410) and the corner bracket (1420) may be located on at least one of the left side, right side, upper side, or lower side of the housing (120). FIGS. 14 to 16 describe the corner protection part (1410) and the corner bracket (1420) with focus.

[0192] The corner protection member (1410) may be a configuration that is coupled to the housing to protect the corner or side of the housing. The corner protection member (1410) may be a configuration that is coupled to the corner or side of the housing to protect the corner or side of the housing. The corner protection member (1410) may be a configuration that is coupled to the corner or side of the housing to protect at least one of the upper left corner, lower left corner, lower right corner, upper right corner, left side, right side, upper side, or lower side. The corner bracket (1420) may be a configuration in which at least a part of the corner protection member (1410) is inserted and coupled, and which is configured to fix the corner protection member (1410) to the housing. FIGS. 14 to 16 illustrate a structure in which the corner protection member (1410) and the corner bracket (1420) are coupled to the corner of the housing (120) according to one embodiment of the present disclosure. This description may also apply to a structure in which a corner protection part (1410) and a corner bracket (1420) are joined to the side of the housing (120).

[0193] The corner protection part (1410) and the corner bracket (1420) may be formed integrally. The corner protection part (1410) and the corner bracket (1420) may also be formed by double injection molding. However, this is not limited thereto, and the corner protection part (1410) and the corner bracket (1420) may be formed individually and assembled.

[0194] The material of the corner protection part (1410) may include at least one of urethane, rubber, plastic, or silicone. Additionally, the material of the corner bracket (1420) may include at least one of urethane, metal, or plastic. The corner bracket (1420) may include at least one of aluminum or stainless steel. The corner bracket (1420) may be any one of rubber, plastic, metal, or carbon. The corner bracket (1420) may have a different strength from the corner protection part (1410). However, it is not limited thereto, and the corner bracket (1420) may have the same strength as the corner protection part (1410). The strength or hardness of the corner bracket (1420) may be greater than or equal to the strength or hardness of the corner protection part (1410).

[0195] The corner bracket (1420) may include a protection insertion hole (1421) for inserting a corner protection part (1410). The protection insertion hole (1421) may be surrounded by a protection cover (1422). That is, the protection cover (1422) may have a protection insertion hole (1421) formed therein for inserting the corner protection part (1410). The corner bracket (1420) may include a connecting plate (1423). The protection cover (1422) may be connected vertically to the connecting plate (1423). The connecting plate (1423) may be parallel to the rear surface (123) of the housing or the front surface (121) of the housing.

[0196] A space (1531, 1532, 1533, 1534) may be formed between the corner protection part (1410) and the corner bracket (1420). When the corner protection part (1410) is inserted into the corner bracket (1420), a space (1531, 1532, 1533, 1534) may be formed between the corner protection part (1410) and the corner bracket (1420). At least a portion of the outer surface of the corner protection part (1410) may face at least a portion of the inner surface of the corner bracket (1420), but may not come into contact with each other. When the corner protection part (1410) is inserted into the corner bracket (1420), there may be a space (1531, 1532, 1533, 1534) between the perimeter of the corner protection part (1410) and the inner surface of the corner bracket (1420). The area formed by the protection part insertion hole (1421) may be larger than the area of ​​the cross-section of the corner protection part (1410). Since there is a space (1531, 1532, 1533, 1534) between the corner protection part (1410) and the corner bracket (1420) in this way, even if a large force is applied to the corner protection part (1410) due to a fall, contact between the corner protection part (1410) and the corner bracket (1420) can be minimized. That is, since the corner protection part (1410) transmits almost no force to the corner bracket (1420), deformation of the corner bracket (1420), housing (120), or detection panel (110) can be minimized. Therefore, the durability of the radiation detector can be greatly improved.

[0197] The width of the front space (1534) and the rear space (1533) in the space between the corner protection part (1410) and the corner bracket (1420) may be greater than or equal to the width of the first side space (1531) and the second side space (1532). For example, the width of the front space (1534) and the rear space (1533) may be 0.65 mm or more and 0.75 mm or less, and the width of the first side space (1531) and the second side space (1532) may be 0.60 mm or more and 0.70 mm or less. When the corner protection part (1410) passes through the corner bracket (1420), the shape of the corner protection part (1410) may be long in the front-to-back direction. Therefore, the corner protection part (1410) may be more resistant to forces applied to the front or back than to forces applied to the left, right, up, or down. The corner protection part (1410) may be less deformed by force applied to the front or back. Additionally, since the width of the front space (1534) and the rear space (1533) is large, the corner protection part (1410) may rarely deform and come into contact with the corner bracket (1420) due to force applied to the front or back. In other words, the corner protection part (1410) can transmit less force to the corner bracket (1420). Therefore, deformation of the corner bracket (1420), housing (120), or detection panel (110) can be minimized. Consequently, the durability of the radiation detector can be greatly improved.

[0198] The corner protection part (1410) can be slid forward or backward and coupled to a groove (1510) formed in the housing (120). The corner protection part (1410) may include a coupling projection (1411). The coupling projection may extend forward and backward. The coupling projection (1411) of the corner protection part (1410) slides along the groove (1510) formed in the housing (120), so that the corner protection part (1410) can be coupled to the housing (120). By this method of coupling between the corner protection part (1410) and the housing (120), the corner protection part (1410) can be prevented from moving in the diagonal direction (1610). In FIG. 16, the diagonal direction may be the combined direction of the bottom and the left. The corner protection part (1410) can be slid forward relative to the housing and coupled to the housing (120). A movement limiting member (1520) may be formed in the housing (120) to limit the movement of the corner protection member (1410). By means of the movement limiting member (1520), the corner protection member (1410) may slide forward and stop at a predetermined position. However, it is not limited to this, and the corner protection member (1410) may slide backward relative to the housing and be coupled to the housing (120).

[0199] In addition, it is not limited thereto, at least one of the corner protection part (1410) or the corner bracket (1420) may be bonded to the housing (120). A separate adhesive may be used for bonding. However, it is not limited thereto, and at least one of the housing (120), the corner protection part (1410), or the corner bracket (1420) may be bonded by heat without a separate adhesive.

[0200] The corner bracket (1420) can be fixed to the housing (120) to prevent the corner protection part (1410) from detaching from the housing (120). The corner bracket (1420) can be screw-coupled to the housing (120). For example, a screw can be coupled to the rear surface (123) of the housing (120) by passing through a screw hole formed in the coupling plate (1423) of the corner bracket (1420). However, it is not limited thereto, and a screw can be coupled to the front surface (121) of the housing (120) by passing through a screw hole formed in the coupling plate (1423) of the corner bracket (1420). However, it is not limited thereto, and the corner bracket (1420) can be coupled to the housing (120) with an adhesive or physically coupled by a groove and a protrusion.

[0201] If the corner protection part (1410) slides forward relative to the housing and is coupled to the housing (120), the coupling plate (1423) is coupled to the rear surface (123) of the housing to prevent the corner protection part (1410) from moving backward. If the corner protection part (1410) slides backward relative to the housing and is coupled to the housing (120), the coupling plate (1423) is coupled to the front surface (121) of the housing to prevent the corner protection part (1410) from moving backward. The corner protection part (1410) can be prevented from moving forward and backward by the movement limiting part (1520) and the coupling plate (1423).
