Abstract
Description
Technical Field
[0001] The present invention discloses a bendable radiation detector including a front protection part. More specifically, in order to enhance the durability of the bendable radiation detector, a bendable radiation detector including a detachable front protection part is disclosed. Further, the present invention discloses a bendable radiation detector including wheels. More specifically, the bendable radiation detector can acquire a radiation image while rotating around an object including the wheels.
Background Art
[0002] When using a radiation detector, protection of the detector is required depending on the user and the usage site. This is because the surface of the radiation detector directly affects the radiation image obtained by the detector. Therefore, various methods for protecting the front of the radiation detector have been proposed, but they are difficult to attach and detach. If scratches are made on the surface of the detector, the detector itself may have to be replaced. Also, a case for protecting the detector may be used, but the detector covered by the case becomes large in volume and its usability deteriorates. There is a problem that the detector must be separated from the case when the detector is put into a storage box or charged. Also, the distance between the subject and the detector may increase due to the case, resulting in a deterioration in the quality of the radiation image. In particular, in order to apply a case to a bendable radiation detector, the case must also be bendable, which is difficult to manufacture.
[0003] Furthermore, radiation detectors sometimes rotate around a subject to capture images. As radiation detectors become larger, rotating them around a subject becomes difficult, and moving the detector can change the distance between the detector and the subject. Therefore, methods are being studied to move radiation detectors while maintaining a constant distance from the subject. For example, detectors have sometimes been equipped with arms, but the arms themselves are heavy and fixed, making it impossible to realize portable detectors. Also, arms were sometimes unsuitable for bendable detectors to move across the rounded surface of the subject. [Prior art documents] [Patent Documents]
[0004] [Patent Document 1] Korean application number 10-2012-0119945 [Patent Document 2] Korean application number 10-2014-0103875 [Overview of the Initiative] [Problems that the invention aims to solve]
[0005] This disclosure relates to a front protective section for protecting the surface of a portable, bendable radiation detector. Furthermore, this disclosure relates to a portable, bendable radiation detector that can be moved while maintaining a certain distance from an object having a rounded surface.
[0006] However, the technical challenges are not limited to those mentioned above; other technical challenges may also exist. [Means for solving the problem]

[0011] One side of the protective cover of the radiation detector of this disclosure is formed to be recessed in a third direction relative to one side of the fixed bracket frame, and the height between the one side of the protective cover and the one side of the fixed bracket frame is greater than or equal to the thickness of the front protective part.
[0012] When the bending support of the radiation detector of this disclosure is extended, a space is formed between one end of the front protective portion and the fixed bracket frame in a first direction, and as the bending support is bent, the space between one end of the front protective portion and the fixed bracket frame in a first direction decreases.
[0013] The radiation detector of this disclosure has at least one left-side fixing portion projecting to the left on the left side of the front protective portion, and at least one right-side fixing portion projecting to the right on the right side of the front protective portion, the right-side fixing portion and the left-side fixing portion are screw-connected to the bending support portion, and the left-side fixing portion and the right-side fixing portion have elongated holes on the left and right sides.

[0015] At least a portion of the four sides of the front protective portion of the radiation detector of this disclosure includes a magnetic coupling portion containing a magnet or a magnetic metal material, and the magnetic coupling portion of the front protective portion is coupled to the magnet or magnetic metal material of the bending support portion, thereby coupling the front protective portion to the bending support portion.
[0016] The radiation detector of this disclosure includes a magnetic coupling portion having a magnet or a magnetic metal material, having a form along the four sides of the front protective portion with a hole in the center, and located in a third direction of the front protective portion, which is coupled with the magnet or magnetic metal material of the bending support portion to connect the front protective portion to the bending support portion.
[0017] The front protective portion of the radiation detector of this disclosure includes a front protective portion connecting portion located at least one of the upper left, upper right, lower left, and lower right sides, and a front protective portion fixing portion connected to the front protective portion connecting portion and connecting the front protective portion to a bending support portion, the front protective portion fixing portion having a surface perpendicular to the front protective portion, and the front protective portion fixing portion has at least one elongated hole extending to the left and right.
[0018] The radiation detector for detecting radiation according to the present disclosure includes a flexible radiation detection panel extending in a first direction for detecting radiation incident on a first surface, a bending support portion in contact with a second surface opposite to the first surface of the radiation detection panel, supporting the radiation detection panel and adjusting the bending of the radiation detection panel about a bending axis parallel to the second direction intersecting the first direction, and a plurality of rotatable detector wheel assemblies located above and below the bending support portion, causing the radiation detector to maintain a predetermined distance from the object and to move along the outer surface of the object.
[0019] The detector wheel assembly of the radiation detector of this disclosure includes a detector wheel having a diameter of 30 mm or less, which protrudes 5 mm or less from the detection panel in a third direction perpendicular to the first and second directions, and a wheel rotation axis parallel to the second direction, which is the rotation center of the detector wheel and is connected to a bending support.
[0020] The wheel rotation axis of the radiation detector of this disclosure has a configuration in which the diameter increases as it moves toward the second direction, the detector wheel has a donut shape, the detector wheel is movable relative to the wheel rotation axis in the second direction and the opposite direction to the second direction, when the detector wheel moves relative to the wheel rotation axis in the second direction and is positioned on the larger diameter portion of the wheel rotation axis, the rotation of the detector wheel is prevented by the frictional force between the inner surface of the detector wheel and the outer surface of the wheel rotation axis, and when the detector wheel moves relative to the wheel rotation axis in the opposite direction to the second direction and is positioned on the smaller diameter portion of the wheel rotation axis, the detector wheel is rotatable.
[0021] The detector wheel of the radiation detector of the present disclosure includes a first wheel, a second wheel positioned in a second direction relative to the first wheel, parallel to the first wheel, and having the same diameter as the first wheel, and a plurality of shafts connecting one side of the first wheel to the other side of the second wheel and extending in a direction parallel to the wheel rotation axis.

[0024] The wheel rotation axis of the radiation detector of the present disclosure has a form in which the diameter increases as it goes in the second direction. The inner peripheral surface corresponding to the rotation hole of the detector wheel is formed of a material for reducing friction with the wheel rotation axis, and the inner peripheral surface corresponding to the fixed hole of the detector wheel is formed of a material for increasing friction with the wheel rotation axis. When the detector wheel moves in the second direction with respect to the wheel rotation axis and is located at the large-diameter portion of the wheel rotation axis, the wheel rotation axis cannot pass through the connection hole of the detector wheel. When the detector wheel moves in the opposite direction of the second direction with respect to the wheel rotation axis and is located at the small-diameter portion of the wheel rotation axis, the wheel rotation axis can pass through the connection hole of the detector wheel. The center of the rotation hole is located at the center of the detector wheel, and the fixed hole is located eccentrically with respect to the detector wheel.
[0025] The detector wheel assembly of the radiation detector of the present disclosure is arranged on the surface in the third direction of the bending support portion, arranged side by side along the first direction, and includes a housing portion protruding 5 mm or less in the third direction from the surface in the third direction of the bending support portion and spherical bearing balls inserted into the housing portion so that the radiation detector moves along the outer peripheral surface of the subject.
[0026] In addition, the program for embodying the operation method of the radiation detector of the present disclosure can be recorded on a computer-readable recording medium.
Advantages of the Invention
[0027] Since the radiation detector of the present disclosure includes a front protection portion, it does not affect the radiation image and can protect the front surface of the bendable radiation detector. In addition, since the front protection portion does not affect the volume of the radiation detector, the user can easily carry the radiation detector equipped with the front protection portion. In addition, the radiation detector equipped with the front protection portion can be freely bent along the shape of the subject.
[0028] Furthermore, since the radiation detector of this disclosure includes a detector wheel assembly, it can move around the subject while maintaining a certain distance from the subject. In addition, the radiation detector equipped with the detector wheel assembly of this disclosure is highly portable and flexible.

[0039] The embodiments are described below in detail with reference to the attached drawings, so that they can be easily implemented by a person with ordinary skill in the art to which this disclosure pertains. Parts not relevant to the description are omitted in order to clearly illustrate this disclosure with the drawings.
[0040] Figure 1 is a front view showing a radiation detector according to one embodiment of the present disclosure. Figure 2 is a front view showing a radiation detector according to one embodiment of the present disclosure.
[0041] The radiation detector will be explained below with reference to Figures 1 and 2.
[0042] The radiation detector 100 of this disclosure may be a device that detects radiation emitted from a radiation source and transmitted through a subject. The radiation may include at least one of X-rays, gamma rays, and certain ultraviolet rays. The radiation detector 100 can detect radiation and acquire a radiation image of the subject. For example, the radiation image acquired by the radiation detector 100 may include at least one of X-ray images and CT (Computed Tomography) images.
[0043] The radiation detector 100 may include a radiation detection panel 110. The radiation detection panel can be classified into two types based on the method of acquiring electrical signals: an indirect conversion type that uses a scintillator to obtain an indirect electrical signal from visible light, and a direct conversion type that uses photoconductors to obtain an electrical signal directly from radiation. Depending on the type of element that generates the electrical signal, it can be classified into a CCD type that uses a charge-coupled device, a CMOS type that uses a crystalline silicon CMOS element, and an a-Si type that uses an amorphous silicon TFT (Thin Film Transistor) substrate.
[0044] The radiation detector 100, including the radiation detection panel 110, is equipped with various sensors and can realize digital image data using electrical signals and positional information of sensors proportional to the amount of incident radiation. The radiation detector 100 can obtain near real-time imaging results, secure high resolution and a wide dynamic range with relatively low radiation, and the storage and processing of imaging results are easy due to the characteristics of digital data. 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 switching elements so that the readout signal unit can read electrical signals. The electrical signals detected by the readout signal unit are converted into image signals through a certain processing process by a controller on the main board, and then transmitted to a display device for displaying X-ray images.
[0045] The radiation detector 100 may include the same configuration as at least one of the following: a pixel array, a readout signal section, a gate driver circuit section, and a main board. The readout signal section may be embodied in a number of film-type ROICs (Read out ICs), each ROIC of which may be connected to the main board by a connector.
[0046] The radiation detector 100 may include a photodetector that detects X-rays and generates an electrical signal, and a readout circuit that reads out the generated electrical signal. After processing the electrical signal output from the readout circuit, the control unit can generate X-ray image data that constitutes an X-ray image. The generated X-ray image data may be stored in a storage unit together with (or separately from) detector status information or information related to X-ray imaging.
[0047] In order to sequentially perform the operations of detecting X-ray information with the radiation detector 100 and transmitting it to an external computer, the radiation detector 100 can use a power and data cable that transmits both power (or power supply) and data communication.
[0048] Furthermore, the radiation detector 100 can utilize WiFi and Gigabit Ethernet for wired / wireless data transmission. Additionally, the control unit of the radiation detector 100 may be connected to communicate with a workstation for variables to drive the video sensor, etc.
[0049] The radiation detection panel 110 may extend in a first direction. The first direction may be to the left, but is not limited to this and may be to the right. The radiation detection panel 110 can detect radiation incident on its first surface, where the first surface may mean the front surface of the radiation detection panel 110. The radiation detection panel 110 may be flexible; that is, it may be bendable due to its flexibility. If the surface of the object has a rounded surface, the radiation detection panel 110 may bend to make close contact with the surface of the object. Because the radiation detection panel 110 is positioned in close contact with the surface of the object, the sharpness of the radiation image may be increased.
[0050] The radiation detector 100 may include a bending support 120. The bending support 120 can be in contact with a second surface of the radiation detection panel 110 that is opposite to the first surface. The second surface may be the rear surface of the radiation detection panel 110. The bending support 120 can support the radiation detection panel 110. As mentioned above, since the radiation detection panel 110 is flexible and bendable, without the bending support 120, it may be difficult to place the radiation detection panel 110 gently against an object. This is because the radiation detection panel 110 is easily deformed by the movement of the object or external force. Therefore, the bending support 120 may be a configuration for supporting the radiation detection panel 110 so that it maintains a certain shape after being bent. The bending support 120 can adjust the bending of the radiation detection panel 110 around a bending axis parallel to a second direction that intersects the first direction. That is, the radiation detection panel 110 can bend as much as the bending support 120 is bent. Here, the second direction could be upward. However, it is not limited to this, and the second direction could also be downward.
[0051] The bending support section 120 can include a variety of configurations for the operation of the radiation detector 100. For example, the bending support section 120 can include at least one of a control section, a communication section, an input section, and an output section for the operation of the radiation detector 100. Also, as shown in Figure 2, the radiation detection panel 110 may be embedded in the bending support section 120. However, it is not limited to these.
[0052] The radiation detector 100 may include a front protective section 130. The front protective section 130 may be positioned in a third direction of the radiation detection panel 110 to protect the radiation detection panel 110, where the third direction may mean the front direction.
[0053] The front protection section 130 can have a larger area than the radiation detection panel 110 exposed from the bending support section 120 so as to cover the radiation detection panel 110. The front protection section 130 can be fixed to the bending support section 120 in part or in part. The front protection section 130 does not necessarily have to be fixed to the radiation detection panel 110. Also, only a portion of the front protection section 130 can be coupled to the bending support section 120. Therefore, the front protection section 130 can be made flexible, and it can protect the radiation detection panel 110 without damaging the bending support section 120 or the radiation detection panel 110. The fixing of the front protection section 130 to the bending support section 120 will be described in detail later.
[0054] Furthermore, the front protective section 130 can be formed as a single unit. That is, the front protective section 130 is not a combination of various components, but can have the shape of a single panel. For example, the front protective section 130 can be manufactured by cutting or folding a single plate of a predetermined material. However, it is not limited to this.
[0055] The front protective section 130 can be flexible. Therefore, the front protective section 130 can bend in response to bending of at least one of the radiation detection panel 110 and the bending support section 120. Furthermore, the front protective section 130 may be detachable from the radiation detection panel 110.
[0056] The radiation detection panel 110 may already be covered by a housing to protect it. Therefore, the radiation detection panel 110 can also be protected from external impacts by the housing. The front protection section 130 may be an additional means of protecting the radiation detection panel 110 in addition to the housing. The housing for protecting the radiation detection panel 110 is bonded to the radiation detection panel 110, and if there is a problem with the material protecting the radiation detection panel 110, the radiation detection panel 110 itself may have to be replaced. In particular, if the object being tested is rough or the radiation detector 100 is used in a rough environment, the radiation detection panel 110 is more likely to be damaged, which may shorten the replacement cycle of the radiation detector 100. The radiation detector 100 of this disclosure includes a replaceable front protection section 130, which can contact or approach the object being tested in place of the radiation detection panel 110. Therefore, scratches occur on the front protective section 130 and not on the radiation detection panel 110, and the user can easily maintain the radiation detector 100 simply by replacing the front protective section 130. In other words, the radiation detector 100 of this disclosure can further increase the durability of the radiation detector 100 by having a detachable front protective section 130.
[0057] The thickness of the front protective section 130 may be between 0.1T and 1T. Furthermore, the material of the front protective section 130 may be a radiation-transmitting material. Additionally, since the material of the front protective section 130 is a resilient material, it may be a material that can be restored to its original state even if bent by external force.
[0058] If the thickness of the front protective section 130 exceeds 1.0T, the transmittance and yield strength will decrease, making it difficult to use in a bendable radiation detector 100 and potentially degrading the quality of the radiation image. Furthermore, if the thickness of the front protective section 130 is 0.1T or less, it may not only fail to perform its protective function but also have reduced durability. The front protective section 130 can have a transmittance of 85% or more. If the transmittance of the front protective section 130 is less than 85%, radiation in a high-energy band must be irradiated to acquire a radiation image, which can adversely affect the circuit board installed in the detector due to excessive energy exposure, potentially increasing the radiation exposure of the subject. If a front protective section 130 of 1T or more is used to protect the circuit board from excessive energy exposure, problems may arise where the front protective section 130 is damaged or fails to recover during bending. The yield strength of the front protective section 130 may be between 20MPa and 30MPa. For example, the restoring force of the front protection section 130 may be 23 MPa. Having such physical properties, the front protection section 130 maintains appropriate elasticity during bending, enabling repetitive bending and flattening motions without affecting the TFT and circuit board of the radiation detector 100.
[0059] The material of the front protection section 130 may be at least one of stainless steel sheet material, copper sheet material, or carbon tool steel. However, it is not limited to these, and the material of the front protection section 130 may be a composite sheet material which is a mixture of at least one of stainless steel material, copper material, and carbon tool steel. The carbon tool steel silver SK1, SK2, SK3, SK4, SK5, SK6, and SK7 may be used for the front protection section 130. Post-treatment may be carried out on the material in order to increase the surface hardness of the front protection section 130. For example, heat treatment, PVD, DLC, etc. can be carried out on the material. By utilizing the material and thickness as described above, the front protection section 130 can return to its original state while maintaining its flexibility. Also, because it allows radiation to pass through, it can have almost no effect on the radiation image. In addition, the front protection section 130 can ensure sufficient strength to adequately protect the radiation detection panel 110. As described above, the material and thickness of the front protective section 130 ensure at least one of the optimal bendability, resilience, and radiotransparency of the front protective section 130, which has been experimentally proven. Furthermore, since only the front protective section 130 is damaged when external material applies force to the detector, the same performance as a new detector can be maintained by replacing only the front protective section 130, which can greatly improve user convenience.
[0060] Referring to Figure 1, the front protection portion 130 may include an upper fixing portion 131. The upper fixing portion 131 may be formed on the upper side of the front protection portion 130, projecting upward. The front protection portion 130 may also include a lower fixing portion 132. The lower fixing portion 132 may be formed on the lower side of the front protection portion 130, projecting downward. Holes may be formed in the upper fixing portion 131 and the lower fixing portion 132. The holes formed in the upper fixing portion 131 and the lower fixing portion 132 may be circular holes rather than elongated holes. However, they are not limited to this. The upper fixing portion 131 and the lower fixing portion 132 can be screw-coupled to the bending support portion 120. That is, a screw can pass through the upper fixing portion 131 and the lower fixing portion 132 and be coupled to the bending support portion 120.
[0061] The upper fixing portion 131 and the lower fixing portion 132 allow the front protective portion 130 to be positioned in the center left to right. That is, the distance from the upper fixing portion 131 and the lower fixing portion 132 to the left edge of the front protective portion 130 and the distance from the upper fixing portion 131 and the lower fixing portion 132 to the right edge of the front protective portion 130 may be the same. However, it is not limited to this.
[0062] The upper fixing portion 131 and the lower fixing portion 132 prevent the front protection portion 130 from moving away from either the radiation detection panel 110 or the bending support portion 120. Furthermore, since the upper fixing portion 131 and the lower fixing portion 132 are formed to protrude from the front protection portion 130, deformation of the front protection portion 130 can be minimized. For example, if force is applied to the front protection portion 130, force will be applied to the fixed upper fixing portion 131 and the lower fixing portion 132, and since deformation of the upper fixing portion 131 and the lower fixing portion 132 has little effect on the generation of the radiation image, deformation of the upper fixing portion 131 and the lower fixing portion 132 does not pose a problem for the use of the radiation detector 100.
[0063] Furthermore, by minimizing the connection between the front protection section 130 and the bending support section 120, damage to the radiation detector 100 by the front protection section 130 can be minimized. This is because, as mentioned above, the front protection section 130 can come into contact with and approach the subject, and therefore can be subjected to significant external forces. Since such external forces are not transmitted to the radiation detection panel 110 or the bending support section 120 through the front protection section 130, damage to the radiation detector 100 can be minimized.
[0064] Furthermore, since the front protective section 130 is in close contact with the radiation detection panel 110 by the upper fixing section 131 and the lower fixing section 132, the image from the radiation detector 100 can be prevented from being distorted by the front protective section 130.
[0065] Referring to Figure 2, the radiation detector 100 may include a fixing bracket 210. The fixing bracket 210 may include a left fixing bracket 210 and a right fixing bracket 210. At least a portion of the fixing bracket 210 may be positioned in at least one third direction of the bending support portion 120 and the front protection portion 130. The third direction may mean forward. The fixing bracket 210 may cover at least a portion of one side of the front protection portion 130. For example, the left fixing bracket 210 may cover at least a portion of the left side of the front protection portion 130. Also, the right fixing bracket 210 may cover at least a portion of the right side of the front protection portion 130. The fixing bracket 210 may be fixed to the bending support portion 120.
[0066] Figure 3 is a diagram illustrating a fixing bracket according to one embodiment of the present disclosure. Figure 4 is also a diagram illustrating a fixing bracket according to one embodiment of the present disclosure.
[0067] Figure 3 shows a perspective view of the radiation detector 100. Figure 4 shows a cross-section of the radiation detector 100. More specifically, Figure 4 shows a cross-section of the fixing bracket 210.
[0068] Referring to Figures 3 and 4, the fixing bracket 210 may include a protective cover 310. The protective cover 310 can cover at least a portion of one side of the front protective section 130. For example, the protective cover 310 can cover at least a portion of the left side of the front protective section 130. Also, the protective cover 310 can cover at least a portion of the right side of the front protective section 130. Referring to Figure 4, the front protective section 130 can be positioned between the protective cover 310 and the bending support section 120. In Figure 3, the fixing bracket 210 is separated by a dotted line, but this is for illustrative purposes only, and the actual fixing bracket 210 does not have a dotted line drawn on it.
[0069] Referring to Figures 3 and 4, the fixing bracket 210 may include a fixing bracket frame 320. The fixing bracket frame 320 may be connected to the protective cover 310 in a first direction. The first direction may be, for example, the left side. However, it is not limited to this, and the first direction may be the right side. The fixing bracket frame 320 may be positioned to the left of the protective cover 310 for the left fixing bracket 210. The fixing bracket frame 320 may be positioned to the right of the protective cover 310 for the right fixing bracket 210. The fixing bracket frame 320 may be in surface contact with the bending support 120 so that the fixing bracket 210 does not wobble in the bending support 120.
[0070] Referring to Figure 3, the fixing bracket 210 may include a fixing bracket fixing portion 330. The fixing bracket fixing portion 330 may be connected to the fixing bracket frame 320 in a second direction, or to the opposite direction of the fixing bracket frame 320, where the second direction may be upward. However, it is not limited to this, and the second direction may be downward. The fixing bracket fixing portion 330 may have a surface perpendicular to the fixing bracket frame 320. That is, if the fixing bracket frame 320 is parallel to the front surface of the bending support portion 120, the fixing bracket fixing portion 330 may be parallel to the lower or upper surface of the bending support portion 120. The fixing bracket fixing portion 330 may be connected to at least one of the lower and upper surfaces of the bending support portion 120. The fixing bracket fixing portion 330 may be screw-connected to the bending support portion 120.
[0071] Referring to Figure 4, one side of the protective cover 310 may be formed to be recessed in a third direction relative to one side of the fixed bracket frame 320. The third direction may mean forward. The reason why one side of the protective cover 310 is recessed in a third direction relative to one side of the fixed bracket frame 320 may be to accommodate space for the protective cover 310 to house the front protective section 130. The height 410 between one side of the protective cover 310 and one side of the fixed bracket frame 320 may be greater than or equal to the thickness of the front protective section 130. By covering at least a portion of the front protective section 130 in this way, the protective cover 310 can help the front protective section 130 bend and return to its original state without problems. It can also help maintain a constant distance between the front protective section 130 and the radiation detection panel 110. That is, the left and right sides of the front protective section 130 can be prevented from moving away from the radiation detection panel 110.
[0072] Furthermore, as shown in Figures 3 and 4, when the bending support portion 120 is expanded, a space 420 may be formed between one end of the front protection portion 130 and the fixed bracket frame 320 in the first direction. Here, the first direction may mean the left direction. Also, unlike in Figures 3 and 4, the space 420 between one end of the front protection portion 130 and the fixed bracket frame 320 in the first direction may gradually decrease as the bending support portion 120 is bent. In this way, when the bending support portion 120 is expanded, a space 420 is formed between one end of the front protection portion 130 and the fixed bracket frame 320 in the first direction, and the protective portion cover 310 can cover the front protection portion 130 without any problems even when the bending support portion 120 is bent.
[0073] Figure 5 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.
[0074] Figures 1 to 4 illustrate an embodiment in which the fixing portion included in the front protective section 130 is located in the center of the left and right sides. However, it is not limited to this. As shown in Figure 5, the fixing portion of the front protective section 130 can be located at a location other than the center of the left and right sides of the front protective section 130. For example, the front protective section 130 may include upper fixing portions 510, 520, 530, and 540. Also, the front protective section 130 may include lower fixing portions 550, 560, 570, and 580.
[0075] Figure 5 illustrates a configuration that includes four upper fixing parts 510, 520, 530, and 540 on the upper side and four lower fixing parts 550, 560, 570, and 580 on the lower side. However, it is not limited to this configuration. There may be two or more upper fixing parts. Similarly, there may be two or more lower fixing parts. Furthermore, the upper fixing parts 510, 520, 530, and 540 and the lower fixing parts 550, 560, 570, and 580 may include elongated holes rather than circular holes. However, it is not limited to this configuration. When multiple upper fixing parts and multiple lower fixing parts are included in this configuration, the front protection part 130 can be firmly fixed to the bending support part 120. Therefore, it is possible to prevent the front protection part 130 from shaking relative to the bending support part 120. In addition, the distance between the front protection part 130 and the radiation detection panel 110 can be maintained at a constant level. Therefore, the image from the radiation detector 100 can be prevented from being distorted by the front protection unit 130.
[0076] Figure 6 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.
[0077] The front protective section 130 may include left-side fixing sections 610, 620 and right-side fixing sections 630, 640. At least one left-side fixing section 610, 620 may be formed projecting to the left on the left side of the front protective section 130. Also, at least one right-side fixing section 630, 640 may be formed projecting to the right on the right side of the front protective section 130. The right-side fixing sections 630, 640 and the left-side fixing sections 610, 620 can be screw-connected to the bending support section. The left-side fixing sections 610, 620 and the right-side fixing sections 630, 640 may have elongated holes that are long from side to side.
[0078] When the front protection section 130 includes the left-side fixing sections 610, 620 and the right-side fixing sections 630, 640, the front protection section 130 can be firmly fixed to the bending support section 120. Therefore, it is possible to prevent the front protection section 130 from shaking relative to the bending support section 120. In addition, the distance between the front protection section 130 and the radiation detection panel 110 can be kept constant. Therefore, the image of the radiation detector 100 can be prevented from being distorted by the front protection section 130. Furthermore, the right-side fixing sections 630, 640 and the left-side fixing sections 610, 620 can prevent deformation of the front protection section 130.
[0079] In Figure 5, the front protective section 130 includes upper fixing parts 510, 520, 530, 540 and lower fixing parts 550, 560, 570, 580. Also, in Figure 6, the front protective section 130 includes left fixing parts 610, 620 and right fixing parts 630, 640. Combining these, the front protective section 130 can include upper fixing parts 510, 520, 530, 540, lower fixing parts 550, 560, 570, 580, left fixing parts 610, 620, and right fixing parts 630, 640. When the front protective section 130 includes upper fixing sections 510, 520, 530, 540, lower fixing sections 550, 560, 570, 580, left-side fixing sections 610, 620, and right-side fixing sections 630, 640, the front protective section 130 can be firmly fixed to the bending support section 120. Therefore, the front protective section 130 can be prevented from shaking relative to the bending support section 120.
[0080] Figure 7 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.
[0081] Referring to Figure 7, similar to Figure 6, the front protection section 130 may include left-side fixing sections 610, 620 and right-side fixing sections 630, 640. In addition, the front protection section 130 may include an upper bracket 710 and a lower bracket 720. The upper bracket 710 and the lower bracket 720 can prevent the front protection section 130 from lifting away from the radiation detection panel 110 and the bending support section 120.
[0082] The upper bracket 710 and the lower bracket 720 can be extended vertically. One side of the upper bracket 710 is screw-connected to the bending support 120, and the other side can contact the front protection 130. Therefore, the upper side of the front protection 130 can be fixed by the upper bracket 710. The other side of the lower bracket 720 is screw-connected to the bending support 120, and one side can contact the front protection 130. Therefore, the lower side of the front protection 130 can be fixed by the lower bracket 720. Unlike in Figure 1, the upper and lower sides of the front protection 130 are not fixed to the bending support 120, but are fixed by frictional force from the upper bracket 710 and the lower bracket 720, so that the front protection 130 can move slightly relative to the bending support 120, and deformation of the front protection 130 due to bending can be prevented. Furthermore, since the upper bracket 710 and the lower bracket 720 can rotate around an axis extending in the front-to-back direction to detach the front protection section 130 from the bending support section 120, the ease of assembly of the front protection section 130 may be improved. Also, since the front protection section 130 can be moved to the left or right side and detached from the bending support section 120 while the upper bracket 710 and the lower bracket 720 remain stationary, the ease of assembly of the front protection section 130 may be improved.
[0083] Figure 8 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.
[0084] The radiation detector 100 may include fixing brackets 810 and 820. At least a portion of the fixing brackets 810 and 820 may be positioned in at least one third direction among the bending support portion 120 and the front protection portion 130. The third direction may be forward, but is not limited to this, and may also be backward. The fixing brackets may extend in a first direction, which may be to the right, but is not limited to this. The fixing brackets 810 and 820 may include an upper fixing bracket 810 and a lower fixing bracket 820.
[0085] The fixing brackets 810 and 820 can cover at least a portion of one side of the front protection section 130. For example, the upper fixing bracket 810 can cover at least a portion of the upper side of the front protection section 130. The lower fixing bracket 820 can cover at least a portion of the lower side of the front protection section 130. The fixing brackets 810 and 820 can be fixed to the bending support section 120. For example, the fixing brackets 810 and 820 can be screw-connected to the bending support section 120.
[0086] The upper fixing bracket 810 may include upper detachment prevention parts 811, 812, and 813 that protrude downward to prevent the front protective part 130 from detaching. Figure 8 shows three upper detachment prevention parts 811, 812, and 813, but is not limited to this, and there may be two or more upper detachment prevention parts. The left-right lengths of the upper detachment prevention parts 811, 812, and 813 may become shorter as they move towards the center of the front protective part 130, and longer as they move towards the left or right side of the front protective part 130. For example, the left-right length of the upper detachment prevention part 812 located in the center may be shorter than the left-right lengths of the upper detachment prevention part 811 located on the left and the upper detachment prevention part 813 located on the right. In this way, the left-right lengths of the upper detachment prevention parts 811, 812, and 813 become shorter as they move towards the center of the front protective part 130, which can reduce deformation of the front protective part 130. Furthermore, by increasing the flexibility of the front protective section 130, the surface of the radiation detector 100 can come into close contact with the surface of a round object.
[0087] The lower fixing bracket 820 may include lower detachment prevention parts 821, 822, and 823 that protrude upward to prevent the front protective part 130 from detaching. Figure 8 shows three lower detachment prevention parts 821, 822, and 823, but is not limited to this, and there may be two or more lower detachment prevention parts. The left-right lengths of the lower detachment prevention parts 821, 822, and 823 may become shorter as they move towards the center of the front protective part 130, and longer as they move towards the left or right side of the front protective part 130. For example, the left-right length of the lower detachment prevention part 822 located in the center may be shorter than the left-right lengths of the lower detachment prevention part 821 located on the left and the lower detachment prevention part 823 located on the right. In this way, the left-right lengths of the lower detachment prevention parts 821, 822, and 823 become shorter as they move towards the center of the front protective part 130, which can reduce deformation of the front protective part 130. Furthermore, by increasing the flexibility of the front protective section 130, the surface of the radiation detector 100 can come into close contact with the surface of a round object.
[0088] Figure 9 may be a drawing illustrating the connection between a bending support and a front protection according to one embodiment of the present disclosure.
[0089] Referring to Figure 9, the bending support portion 120 may be coupled to an upper fixing bracket 810 and a lower fixing bracket 820. The front protection portion 130 may slide along the upper fixing bracket 810 and the lower fixing bracket 820 to be coupled to the bending support portion 120. The front protection portion 130 may be guided by the upper fixing bracket 810 and the lower fixing bracket 820. In addition, the front protection portion 130 may be prevented from detaching from the bending support portion 120 by upper detachment prevention portions 811, 812, 813 and lower detachment prevention portions 821, 822, 823.
[0090] The upper detachment prevention parts 811, 812, 813 and the lower detachment prevention parts 821, 822, 823 contact the front protection part 130 and can fix the front protection part 130 to the bending support part 120. The rear surfaces of the upper detachment prevention parts 811, 812, 813 and the lower detachment prevention parts 821, 822, 823 that contact the front protection part 130 can include an elastic material. For example, the elastic material can include at least one of rubber, urethane, and silicone. The upper detachment prevention parts 811, 812, 813 and the lower detachment prevention parts 821, 822, 823 contact the front protection part 130 and can prevent the front protection part 130 from detaching from the bending support part 120 by frictional force. However, this is not limited to this, and the upper detachment prevention parts 811, 812, 813 and the lower detachment prevention parts 821, 822, 823 do not need to be in contact with the front protection part 130.
[0091] According to the radiation detector 100 in Figure 9, the user can fix the front protective section 130 to the bending support section 120 simply by sliding the front protective section 130 along the upper fixing bracket 810 and lower fixing bracket 820 of the bending support section 120, thus increasing convenience.
[0092] Figure 10 is a drawing illustrating an additional embodiment of the front protection portion according to one embodiment of the present disclosure.
[0093] Figure 10 can show a front protective section 130 formed by combining Figures 5 and 6. Referring to Figures 5, 6, and 10, the front protective section 130 may include upper fixing sections 510, 520, 530, and 540. The front protective section 130 may also include lower fixing sections 550, 560, 570, and 580. Furthermore, the front protective section 130 may include left fixing sections 610, 620 and right fixing sections 630, and 640.
[0094] The upper fixing parts 510, 520, 530, 540, the lower fixing parts 550, 560, 570, 580, the right fixing parts 630, 640, and the left fixing parts 610, 620 can be screw-connected to the bending support. The upper fixing parts 510, 520, 530, 540, the lower fixing parts 550, 560, 570, 580, the left fixing parts 610, 620, and the right fixing parts 630, 640 can have elongated holes that are long from side to side. Therefore, the front protection part 130 can be connected to the bending support part 120 so that it is movable from side to side. Since the front protection part 130 is movable from side to side relative to the bending support part 120, the front protection part 130 can not be deformed even if the process of bending and unbending the front protection part 130 is repeated. Furthermore, the front protective section 130 can be firmly connected to the bending support section 120 by the upper fixing sections 510, 520, 530, 540, the lower fixing sections 550, 560, 570, 580, the left fixing sections 610, 620, and the right fixing sections 630, 640.
[0095] Figure 11 may be a drawing illustrating a screw coupling according to one embodiment of the present disclosure.
[0096] As described above, the front protective section 130 can be screw-connected to the bending support section 120. That is, the screw can pass through a hole in the front protective section 130 and be connected to the bending support section 120.
[0097] Referring to Figure 11(A), at least one of the upper fixing parts 510, 520, 530, 540, the lower fixing parts 550, 560, 570, 580, the left fixing parts 610, 620, and the right fixing parts 630, 640 can have elongated holes that are longer in the left-right direction. Therefore, even when the screw 1110 is connected, the front protective part 130 can move left and right relative to the bending support part 120. Because the front protective part 130 can move left and right relative to the bending support part 120, the front protective part 130 can avoid putting stress on the radiation detection panel 110 and the bending support part 120 when the bending support part 120 is bent. The durability of the radiation detector 100 can be increased.
[0098] Referring to Figure 11(B), at least one of the upper fixing parts 510, 520, 530, 540, the lower fixing parts 550, 560, 570, 580, the left fixing parts 610, 620, and the right fixing parts 630, 640 can have a circular hole. The diameter of the circular hole may be larger than the diameter of the screw 1120. Here, the screw 1120 may mean the part in which the threads are formed. The diameter of the circular hole may be 1.5 times or more and 2 times or less than the diameter of the screw 1120. Therefore, the front protection part 130 can move left, right, up, and down relative to the bending support part 120. Because the front protection part 130 can move left, right, up, and down relative to the bending support part 120, the front protection part 130 can avoid putting stress on the radiation detection panel 110 and the bending support part 120 when the bending support part 120 is bent. As shown in Figure 11(B), the diameter of the screw head may be larger than the diameter of at least one of the circular holes among the upper fixing parts 510, 520, 530, 540, the lower fixing parts 550, 560, 570, 580, the left fixing parts 610, 620, and the right fixing parts 630, 640.
[0099] Figure 12 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure. Figure 13 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.
[0100] The front protective section 130 may include a magnetic coupling section. The magnetic coupling section may be located on the front or rear surface of the front protective section 130. The magnetic coupling section may be located on at least part of the four sides of the front protective section 130. The magnetic coupling section may include a magnet or a magnetic metal material.
[0101] The magnetic coupling portion of the front protection portion 130 can be coupled to the magnet or magnetic metal material of the bending support portion 120. Therefore, the front protection portion 130 can be coupled to the bending support portion 120. When using the magnetic coupling portion in this way, the front protection portion 130 and the bending support portion 120 can be coupled simply by placing the front protection portion 130 on the bending support portion 120, making the assembly of the front protection portion 130 and the bending support portion 120 very easy. Furthermore, by roughly aligning the positions of the front protection portion 130 and the bending support portion 120, the front protection portion 130 will be coupled to the bending support portion 120 in a specific direction and position by magnetic force, which can increase user convenience. It is also possible to use the polarity of the magnet to cause the front protection portion 130 to be coupled to the bending support portion 120 only when it is positioned in a specific direction.
[0102] Figure 12(A) shows the magnetic coupling portion 1210. The magnetic coupling portion 1210 may include at least one of the left magnetic coupling portion 1211, the upper magnetic coupling portion 1212, the right magnetic coupling portion 1213, and the lower magnetic coupling portion 1214. The magnetic coupling portion 1210 may be bonded to the rear surface of the front protective portion 130. The magnetic force between the magnetic coupling portion 1210 and the bending support portion 120 allows the front protective portion 130 to be coupled to the bending support portion 120.
[0103] However, the magnetic coupling portion 1210 does not have to be bonded to the front protection portion 130. Referring to Figure 12(B), the user can place the front protection portion 130 on top of the bending support portion 120. The front protection portion 130 may be in a movable position in front of the bending support portion 120. At this time, the magnetic coupling portion 1210 can be positioned in front of the front protection portion 130. The magnetic coupling portion 1210 can be coupled to the bending support portion 120 by magnetic force. The front protection portion 130 between the magnetic coupling portion 1210 and the bending support portion 120 can be fixed to the bending support portion 120 by friction.
[0104] Figure 13(A) shows the magnetic coupling portion 1310. The magnetic coupling portion 1310 can be bonded to the rear surface of the front protective portion 130. The magnetic force between the magnetic coupling portion 1310 and the bending support portion 120 allows the front protective portion 130 to be coupled to the bending support portion 120.
[0105] However, the magnetic coupling portion 1310 does not have to be bonded to the front protective portion 130. The magnetic coupling portion 1310 may have a magnet or a magnetic metal material. The magnetic coupling portion 1310 may be formed along the four sides of the front protective portion. The magnetic coupling portion 1310 may have a hole 1320 in the center. Referring to Figure 13(B), the magnetic coupling portion 1310 may be located in a third direction of the front protective portion 130. The third direction may mean forward. The magnetic coupling portion 1310 can be coupled to the magnet or magnetic metal material of the bending support portion 120 to bond the front protective portion 130 to the bending support portion 120. The front protective portion 130 between the magnetic coupling portion 1310 and the bending support portion 120 may be fixed to the bending support portion 120 by friction.
[0106] The radiation detector 100 may include a control unit and a sensor unit. The sensor unit may be a sensor that senses a magnetic field. The sensor unit may be located on the bending support unit 120. The control unit can sense whether the magnetic coupling units 1210 and 1310 are coupled to the bending support unit 120 based on the signal from the sensor unit. That is, if the sensor unit senses a magnetic flux greater than or equal to the critical magnetic flux, the control unit can determine that the magnetic coupling units 1210 and 1310 are coupled to the bending support unit 120. Also, if the sensor unit senses a magnetic force greater than or equal to the critical magnetic force, the control unit can determine that the magnetic coupling units 1210 and 1310 are coupled to the bending support unit 120. Also, if the sensor unit senses a magnetic flux less than the critical magnetic flux, the control unit can determine that the magnetic coupling units 1210 and 1310 are not coupled to the bending support unit 120. The fact that the magnetic coupling parts 1210 and 1310 are coupled to the bending support part 120 may mean that the front protection part 130 is coupled to the bending support part 120. The bending support part 120 may include multiple sensor parts. The control unit can determine that the magnetic coupling parts 1210 and 1310 are coupled to the bending support part 120 only if the magnetic flux measured by the multiple sensor parts is equal to or greater than the critical magnetic flux.
[0107] Figure 14 is a drawing illustrating a front protection portion according to one embodiment of the present disclosure.
[0108] Referring to Figure 14(A), the front protection section 130 may include front protection section connecting sections 1411, 1412, 1413, and 1414 located on at least one of the upper left, upper right, lower left, and lower right sides. The front protection section connecting sections 1411 and 1412 located on the upper left and upper right sides may extend upward from the front protection section 130. The front protection section connecting sections 1413 and 1414 located on the lower left and lower right sides may extend downward from the front protection section 130.
[0109] Referring to Figure 14(A), the front protection section 130 may include front protection section fixing sections 1421, 1422, 1423, and 1424. The front protection section fixing sections 1421, 1422, 1423, and 1424 may be connected to front protection section connecting sections 1411, 1412, 1413, and 1414. The front protection section fixing sections 1421, 1422, 1423, and 1424 may be configured to connect the front protection section 130 to the bending support section 120. The front protection section fixing sections 1421, 1422, 1423, and 1424 may also have surfaces perpendicular to the front protection section. The upper left front protection section fixing section 1421 may be screw-connected to the left side of the upper surface of the bending support section 120. The upper right front protection section fixing section 1422 may be screw-connected to the right side of the upper surface of the bending support section 120. The lower left front protection fixing part 1423 can be screw-connected to the left side of the lower surface of the bending support part 120. The lower right front protection fixing part 1424 can be screw-connected to the right side of the lower surface of the bending support part 120. At least one elongated hole extending to the left and right may be formed in the front protection fixing parts 1421, 1422, 1423, and 1424. The elongated hole allows the front protection part 130 to move left and right relative to the bending support part 120, so that when the bending support part 120 bends, the front protection part 130 does not put stress on the radiation detection panel 110 and the bending support part 120. The durability of the radiation detector 100 can be increased.
[0110] Figure 15 may be a diagram illustrating a radiation detector according to one embodiment of the present disclosure. Figure 16 may be a diagram illustrating a radiation detector according to one embodiment of the present disclosure.
[0111] Figure 16 is a simplified plan view of the subject and the radiation detector 100. Referring to Figures 15 and 16, the radiation detector 100 for detecting radiation can rotate around the subject 1510 and take images. The subject 1510 may be a spherical or cylindrical object. The subject 1510 may be, for example, a pipe. The radiation detector 100 can take radiation images while rotating around the outer surface of the subject 1510 to detect cracks in the pipe. Although not shown in Figures 15 and 16, a source assembly for irradiating radiation may be located on the opposite side of the radiation detector 100.
[0112] Referring to Figure 16, since the radiation detector 100 is in close proximity to the subject 1510 to capture a radiation image, the radiation detection panel 110 of the radiation detector 100 may be damaged by the subject 1510. However, as mentioned above, since the radiation detector 100 of this disclosure includes a front protection section 130, the radiation detection panel 110 is not damaged, and the performance of the radiation detector 100 can be maintained for a long period of time.
[0113] As mentioned above, the radiation detector 100 may include a flexible radiation detection panel 110 that extends in a first direction and detects radiation incident on the first surface. Referring to Figures 15 and 16, the radiation detection panel 110 can be bent to conform to the shape of the object 1510. The radiation detection panel 110 has already been described, so a redundant explanation will be omitted.
[0114] The radiation detector 100 is in contact with a second surface of the radiation detection panel opposite to the first surface, supports the radiation detection panel 110, and may include a bending support section 120 that adjusts the bending of the radiation detection panel about a bending axis parallel to the second direction intersecting the first direction. The bending support section 120 has already been described, so a redundant explanation will be omitted.
[0115] Referring to Figures 15 and 16, the radiation detector 100 may include a plurality of detector wheel assemblies 1520. The plurality of detector wheel assemblies 1520 can be located on at least one of the upper and lower sides of the bending support 120. Although Figures 15 and 16 illustrate the radiation detector 100 as including a plurality of detector wheel assemblies 1520, it is not limited to this configuration, and the radiation detector 100 may include one or more detector wheel assemblies 1520. The plurality of detector wheel assemblies 1520 can be fixed to the bending support 120.
[0116] Multiple detector wheel assemblies 1520 allow the radiation detector 100 to maintain a predetermined distance from the cylindrical subject 1510. In this way, the radiation detector 100 can conveniently rotate around the subject 1510 while obtaining radiation images, thus obtaining high-quality images of the subject 1510 and improving user convenience. This is because, without multiple detector wheel assemblies 1520, the user would have to repeatedly fix the radiation detector 100 at a specific position on the subject 1510, take an image, remove the radiation detector 100 from the subject 1510, and then fix the radiation detector 100 at the specific position on the subject 1510 again.
[0117] Although the radiation detector 100 may leave scratches on the surface of the subject 1510, the radiation detector 100 of this disclosure includes a plurality of detector wheel assemblies 1520 to prevent the radiation detector 100 from coming into contact with the subject 1510, thereby protecting the surface of the subject 1510 from the radiation detector 100. Furthermore, because the radiation detector 100 rotates around the subject 1510 in close proximity to it, the radiation detector 100 may be scratched by the subject 1510. In particular, scratches may occur on the radiation detection panel 110, which is in close proximity to the subject 1510, but the front protection unit 130 can prevent scratches on the radiation detection panel 110. The radiation detector 100 of this disclosure can prevent scratches on the radiation detection panel 110 and maintain high quality radiation images.
[0118] The multiple detector wheel assemblies 1520 may include a suspension section. Therefore, when the multiple detector wheel assemblies 1520 rotate around the subject 1510, the impact energy applied to the radiation detector 100 or the subject 1510 can be absorbed by the suspension section. The multiple detector wheel assemblies 1520 can be configured so that the radiation detector 100 moves along the outer surface of the subject. The multiple detector wheel assemblies 1520 may also be rotatable. More specifically, the detector wheels included in the multiple detector wheel assemblies 1520 may rotate around a wheel rotation axis. The wheel rotation axis may be parallel to a second direction.
[0119] Figure 17 is a drawing illustrating a detector wheel assembly according to one embodiment of the present disclosure.
[0120] Figure 17 illustrates a detector wheel assembly in a different form from those shown in Figures 15 and 16. According to various embodiments of this disclosure, the detector wheel assembly may have a bearing configuration. If the detector wheel assembly is in a bearing configuration, the radiation detector 100 may not include a detector wheel assembly 1520 in the form shown in Figures 15 and 16. However, the radiation detector 100 may include a detector wheel assembly in a bearing configuration along with a detector wheel assembly 1520 in the form shown in Figures 15 and 16.
[0121] Referring to Figure 17(A), the detector wheel assembly may include a housing 1710 and bearing balls 1720. The housing 1710 may be positioned on a third-direction face of the bending support 120. The third-direction face may mean the front surface. The third-direction face may mean the surface facing the object. The housing 1710 may be arranged side by side along a first direction. For example, in Figure 18, the detector wheel assembly may be positioned along the front edge 1890 of the detector. The bearing balls 1720 of the detector wheel assembly may be positioned facing forward on the front surface of the detector. The housing 1710 may be positioned behind the bearing balls 1720. By positioning the detector wheel assembly along the front edge 1890 of the detector, the front surface of the detector does not come into contact with the object 1510, thus preventing damage to the front surface of the detector from the object 1510. The detector wheel assembly also allows the detector to rotate smoothly around the object 1510. Therefore, the user can easily position the detector at various angles relative to the subject 1510, and conveniently obtain radiographic images of the subject 1510 at various angles.
[0122] The housing portion 1710 may protrude 5 mm or less in the third direction from the third direction surface of the bending support portion 120. That is, the distance 1730 from the surface of the bending support portion 120 to the end of the housing portion 1710 in the third direction may be 5 mm or less.
[0123] Referring to Figure 17(A), the bearing ball 1720 may be spherical. The bearing ball 1720 can be inserted into the housing 1710 so that the radiation detector 100 moves along the outer surface of the object.
[0124] Although not shown in Figure 17, the radiation detector 100 may include a braking mechanism. The braking mechanism may be positioned on the third-direction surface of the bending support portion 120. The braking mechanism can move in the third direction based on user input and make contact with the object 1510. The frictional force between the braking mechanism and the object 1510 can prevent the radiation detector 100 from moving relative to the object 1510. Alternatively, the braking mechanism can move in the opposite direction to the third direction based on user input. In this case, the radiation detector 100 may be able to move freely relative to the object 1510.
[0125] Referring to Figure 17(B), the detector wheel assembly may include a suspension section. More specifically, the housing 1710 may include a suspension section. The suspension section may include an elastic body that presses the bearing ball 1720 in a third direction. When the object 1510 comes into contact with the bearing ball 1720, the bearing ball 1720 may be pushed in the opposite direction (rearward) of the third direction. Also, when the object 1510 moves away from the bearing ball 1720, the position of the bearing ball 1720 may again be the same as in Figure 17(A). The suspension section may absorb the impact energy applied to the radiation detector 100 and the object 1510.
[0126] Figure 18 is a diagram illustrating a radiation detector according to one embodiment of the present disclosure.
[0127] Figure 18 illustrates a detector wheel assembly including a wheel, as shown in Figures 15 and 16. The detector wheel assembly 1520 may be positioned above or below the bending support 120. The detector wheel assembly 1520 may include a left upper detector wheel assembly 1811, a right upper detector wheel assembly 1812, a left lower detector wheel assembly 1813, and a right lower detector wheel assembly 1814.
[0128] The detector wheel included in the detector wheel assembly 1520 may protrude 5 mm or less in a third direction from the radiation detection panel 110. Here, the third direction may be perpendicular to the first and second directions. For example, the first direction may be to the left, the second direction may be upward, and the third direction may be forward. The detector wheel included in the detector wheel assembly 1520 may protrude 5 mm or less in a third direction from the front protective section 130. The diameter of the detector wheel included in the detector wheel assembly 1520 may be 30 mm or less, but is not limited to this. The material of the detector wheel may be a material that prevents the detector wheel from slipping away from the object 1510. For example, the material of the detector wheel may be a rubber series or a urethane material.
[0129] The wheel rotation axis included in the detector wheel assembly 1520 may be parallel to the second direction; that is, the wheel rotation axis may extend in a direction parallel to the second direction. The wheel rotation axis may be the rotation center of the detector wheel. The wheel rotation axis may be connected to the bending support 120. The wheel rotation axis may be fixed to the bending support 120 and not rotate. However, it is not limited to this, and the wheel rotation axis may be connected to the bending support 120 and rotate together with the detector wheel.
[0130] Figure 19 is a drawing showing a detector wheel assembly according to one embodiment of the present disclosure. Figure 20 is a drawing showing a detector wheel assembly according to one embodiment of the present disclosure.
[0131] Referring to Figure 19, the wheel rotation shaft 1920 may have a configuration in which its diameter increases as it moves in a second direction. The second direction may be the upward direction. However, it is not limited to this, and the second direction may also be the downward direction. The wheel rotation shaft 1920 may also have a configuration in which its diameter decreases as it moves in a second direction. For example, the wheel rotation shafts included in the upper left detector wheel assembly 1811 and the upper right detector wheel assembly 1812 may have a configuration in which their diameter increases as they move upward. Also, the lower part of the wheel rotation shafts included in the upper left detector wheel assembly 1811 and the upper right detector wheel assembly 1812 may be fixed to the bending support part 120. The wheel rotation shafts included in the lower left detector wheel assembly 1813 and the lower right detector wheel assembly 1814 may have a configuration in which their diameter increases as they move downward. Furthermore, the upper parts of the wheel rotation axes included in the left lower detector wheel assembly 1813 and the right lower detector wheel assembly 1814 can be fixed to the bending support portion 120.
[0132] The detector wheel 1910 may have a donut shape. The hole formed inside the detector wheel 1910 may have a constant diameter, but is not limited to this. For example, similar to the wheel rotation axis 1920, the hole formed inside the detector wheel 1910 may have a configuration in which the diameter increases as you move in the second direction. The detector wheel 1910 can rotate around the wheel rotation axis 1920.
[0133] The detector wheel 1910 may be movable in a second direction and in the opposite direction to the second direction relative to the wheel rotation axis 1920. The second direction may be upward.
[0134] The detector wheel 1910 may be rotatable if it moves in the opposite direction to the second direction (downward) relative to the wheel rotation axis 1920 and is positioned on the smaller diameter portion of the wheel rotation axis 1920. Referring to Figure 20(A), the detector wheel 1910 can move downward relative to the wheel rotation axis 1920. The detector wheel 1910 may be rotatable because it is not interfered with by the fixed wheel rotation axis 1920. Therefore, the radiation detector 100 can easily move around the subject 1510 by means of a rotatable detector wheel 1910.
[0135] When the detector wheel 1910 moves in a second direction (upward) relative to the wheel rotation axis 1920 and is positioned on the larger diameter portion of the wheel rotation axis, the rotation of the detector wheel 1910 can be prevented by the frictional force between the inner surface of the detector wheel 1910 and the outer surface of the wheel rotation axis 1920. Therefore, the movement of the radiation detector 100 relative to the subject 1510 can be restricted. The radiation detector 100 can capture a radiation image of the subject while stationary. Because the radiation detector 100 is stopped by the detector wheel assembly 1520, the position of the radiation detector 100 relative to the subject 1510 can remain constant, and the sharpness of the radiation image can be increased.
[0136] Figure 21 is a drawing illustrating a detector wheel according to one embodiment of the present disclosure.
[0137] Referring to Figure 21(A), the detector wheel 2110 may include a rotating hole 2113. The rotating hole 2113 can be used to rotate the detector wheel 2110 around its axis of rotation. That is, if the axis of rotation is located in the rotating hole 2113, the detector wheel 2110 can rotate around its axis of rotation. Since the rotating hole 2113 is eccentrically positioned relative to the detector wheel 2110, the detector wheel 2110 can rotate with respect to its eccentric axis. The diameter of the rotating hole 2113 may be larger than or equal to the diameter of the axis of rotation. Also, the inner surface of the detector wheel 2110 forming the rotating hole 2113 may be made of a material with low friction.
[0138] Referring to Figure 21(A), the detector wheel 2110 may include a fixing hole 2111. The fixing hole 2111 may be used to fix the detector wheel 2110 with respect to the wheel rotation axis. That is, if the wheel rotation axis is located at the fixing hole 2111, the detector wheel 2110 may not be able to rotate due to friction between the inner surface of the detector wheel 2110 forming the fixing hole 2111 and the wheel rotation axis. If the detector wheel 2110 does not rotate, the radiation detector 100 may be stopped relative to the object 1510 by friction between the outer surface of the detector wheel and the outer surface of the object. The center of the fixing hole 2111 may be eccentric from the center of the detector wheel 2110. The closer the distance between the center of the fixed hole 2111 and the subject 1510 is to the longest distance between the center of the fixed hole 2111 and the outer surface of the detector wheel 2110, which is the semi-major axis 2124, the stronger the force with which the detector wheel 2110 presses against the subject 1510. Furthermore, the stronger the force with which the detector wheel 2110 presses against the subject 1510, the more firmly the radiation detector 100 and the subject 1510 can be fixed by the detector wheel 2110. The fixed hole 2111 allows the radiation detector 100 to capture a radiation image of the subject 1510 while remaining stationary. The diameter of the fixed hole 2111 may be smaller than or equal to the diameter of the wheel's rotation axis. Also, the inner surface of the detector wheel 2110 forming the fixed hole 2111 may be made of a material with high friction.
[0139] Referring to Figure 21(A), the detector wheel 2110 may include a connecting hole 2112. The connecting hole 2112 may be a passage through which the wheel rotation axis can move between the rotating hole 2113 and the fixed hole 2111. The width of the connecting hole 2112 may be smaller than the diameters of the rotating hole 2113 and the fixed hole 2111. The material forming the connecting hole 2112 in the detector wheel 2110 may be an elastic material. For example, the material forming the connecting hole 2112 may include at least one of rubber, silicone, and urethane, but is not limited thereto.
[0140] Referring to Figure 21(B), the detector wheel 2120 may include a rotating hole 2123. The rotating hole 21223 can be used to rotate the detector wheel 21220 around the wheel axis of rotation. That is, if the wheel axis of rotation is located in the rotating hole 2123, the detector wheel 2120 can rotate around the wheel axis of rotation. The center of the rotating hole 2123 can be located at the center of the detector wheel. Because the rotating hole 2123 is located at the center of the detector wheel 2120, the detector wheel 2110 can rotate with respect to the center of the detector wheel 2120. The diameter of the rotating hole 2123 may be larger than or the same as the diameter of the wheel axis of rotation. Also, the inner circumferential surface of the detector wheel 2120 that forms the rotating hole 2123 may be made of a material with low friction.
[0141] Referring to Figure 21(B), the detector wheel 2120 may include a fixing hole 2121. The fixing hole 2121 may be used to fix the detector wheel 2120 with respect to the wheel rotation axis. That is, if the wheel rotation axis is located at the fixing hole 2121, the detector wheel 2120 may not be able to rotate due to friction between the inner surface of the detector wheel 2120 forming the fixing hole 2121 and the wheel rotation axis. If the detector wheel 2120 does not rotate, the radiation detector 100 may be stopped relative to the object 1510 by friction between the outer surface of the detector wheel and the outer surface of the object. The center of the fixing hole 2121 may be eccentric from the center of the detector wheel 2120. The closer the distance between the center of the fixed hole 2121 and the subject 1510 is to the longest distance between the center of the fixed hole 2121 and the outer surface of the detector wheel 2120, which is the semi-major axis 2124, the stronger the force with which the detector wheel 2120 presses against the subject 1510. Furthermore, the stronger the force with which the detector wheel 2120 presses against the subject 1510, the more firmly the radiation detector 100 and the subject 1510 can be fixed by the detector wheel 2120. The fixed hole 2121 allows the radiation detector 100 to remain stationary while capturing radiation images of the subject 1510. The diameter of the fixed hole 2121 may be smaller than or equal to the diameter of the wheel's rotation axis. Also, the inner surface of the detector wheel 2120 forming the fixed hole 2121 may be made of a material with high friction.
[0142] Referring to Figure 21(B), the detector wheel 2120 may include a connecting hole 2122. The connecting hole 2122 may be a passage through which the wheel rotation axis can move between the rotating hole 2123 and the fixed hole 2121. The width of the connecting hole 2122 may be smaller than the diameters of the rotating hole 2123 and the fixed hole 2121. The material forming the connecting hole 2122 in the detector wheel 2120 may be an elastic material. For example, the material forming the connecting hole 2122 may include at least one of rubber, silicone, and urethane, but is not limited thereto.
[0143] The above describes the structure of the detector wheels 2110 and 2120. Below, the process by which the wheel rotation axis moves between the fixed holes 2111 and 2121 and the rotating holes 2113 and 2123 will be described with reference to Figures 19 to 22. Content already explained in Figures 19 to 21 will be omitted.
[0144] Figure 22 illustrates a radiation detector according to one embodiment of the present disclosure.
[0145] Referring to Figures 19 to 22, the wheel rotation shaft 1920 can be fixed to the bending support portion 120. As shown in Figure 20, the wheel rotation shaft 1920 can have a configuration in which the diameter increases as you move in the second direction. As mentioned above, the inner circumferential surface of the detector wheel 2120 corresponding to the rotation hole 2123 may be formed of a material that reduces friction with the wheel rotation shaft 1920. Also, the inner circumferential surface of the detector wheel 2120 corresponding to the fixing hole 2121 may be formed of a material that increases friction with the wheel rotation shaft.
[0146] When the detector wheel 2120 moves in a second direction relative to the wheel rotation axis 1920 and is positioned on the larger diameter portion of the wheel rotation axis 1920, the wheel rotation axis 1920 cannot pass through the connecting hole of the detector wheel 2120. Therefore, the detector wheel 2120 cannot move the wheel rotation axis 1920 from the fixed hole 2121 to the rotating hole 2123 or from the rotating hole 2123 to the fixed hole 2121.
[0147] Furthermore, when the detector wheel 2120 moves in the opposite direction to the second direction relative to the wheel rotation axis 1920 and is positioned on the smaller diameter portion of the wheel rotation axis 1920, the wheel rotation axis 1920 can pass through the connecting hole of the detector wheel 2120. Therefore, the detector wheel 2120 can move the wheel rotation axis 1920 from the fixed hole 2121 to the rotating hole 2123, or from the rotating hole 2123 to the fixed hole 2121.
[0148] Referring to Figure 22(A), the user can move the detector wheel 2120 in the manner described above to position the wheel rotation axis 1920 in the fixing hole 2121 of the detector wheel 2120. Furthermore, the distance between the center of the fixing hole 2121 and the subject 1510 can be such that the detector wheel 2120 is positioned close to the longest distance between the center of the fixing hole 2121 and the outer surface of the detector wheel 2120, which is the semi-major axis 2124. Therefore, the radiation detector 100 can be fixed to the subject 1510 by the frictional force between the detector wheel 2120 and the subject 1510, and by the frictional force between the connecting band 2210 and the subject 1510. Thus, the radiation detector 100 can capture highly sharp radiation images while fixed in place.
[0149] Referring to Figure 22(B), the user can move the detector wheel 2120 in the manner described above to position the wheel rotation axis 1920 in the rotation hole 2123 of the detector wheel 2120. Furthermore, the detector wheel 2120 can either not come into contact with the object 1510, or even if the detector wheel 2120 and the object 1510 come into contact, the detector wheel 2120 can rotate around the wheel rotation axis 1920. Therefore, the radiation detector 100 can move freely away from the object 1510.
[0150] Figure 23 is a diagram illustrating a detector wheel according to one embodiment of the present disclosure. Figure 24 is a diagram illustrating a detector wheel according to one embodiment of the present disclosure.
[0151] The detector wheel assembly 1520 may be coupled to the bending support 120. The detector wheel assembly 1520 may include a detector wheel 2120. The detector wheel 2120 may include a first wheel 2310. The detector wheel 2120 may also include a second wheel 2320. The second wheel 2320 may be positioned in a second direction relative to the first wheel 2310. The second direction may be upward, but is not limited to this, and may be downward. The second wheel 2320 may be parallel to the first wheel 2310 and have the same diameter as the first wheel 2310. However, is not limited to this, and the diameter of the second wheel 2320 may be different from the diameter of the first wheel 2310.
[0152] Referring to Figure 23(A), the detector wheel 2120 may include multiple shafts 2330. The multiple shafts 2330 can connect one side of the first wheel 2310 to the other side of the second wheel 2320. The multiple shafts 2330 may also extend in a direction parallel to the wheel rotation axis. The wheel rotation axis extends in a second direction, and the multiple shafts 2330 may also extend in the second direction. As shown in Figure 23(A), the multiple shafts may be cylindrical. However, they are not limited to this, and as shown in Figure 23(B), the multiple shafts may be wing-type.
[0153] Referring to Figure 24, the radiation detector 100 may include a detector wheel assembly 1520, which includes the detector wheel 2120 described in Figure 23. The detector wheel assembly 1520 may be positioned above or below the bending support 120. The detector wheel assembly 1520 may include a left upper detector wheel assembly 2411, a right upper detector wheel assembly 2412, a left lower detector wheel assembly 2413, and a right lower detector wheel assembly 2414.
[0154] Figure 25 is a diagram illustrating a radiation detector according to one embodiment of the present disclosure. Figure 26 is a diagram illustrating a radiation detector according to one embodiment of the present disclosure.
[0155] Referring to Figure 25, the radiation detector 100 may include a connecting band 2210. The connecting band 2210 may be configured to surround the subject together with the bending support 120. That is, the subject 1510 can be located inside the area formed by the connecting band 2210 and the bending support 120.
