  Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings. However, details of dimensions and structures shown in each embodiment are not limited to those shown in the text and the drawings. In this specification, not only X-rays but also α rays, β rays, γ rays, particle rays, cosmic rays, and the like are included in the radiation.

(First embodiment)
The configuration of the radiation imaging system 10 will be described with reference to FIG. FIG. 1 shows a configuration example of a radiation imaging system 10 in the first embodiment.

  The radiation imaging system 10 includes at least a radiation imaging apparatus 100, a control apparatus 200, a radiation generation control apparatus 300, and a radiation source 400.

  The radiation imaging apparatus 100 acquires the radiation image data of the subject based on the radiation emitted from the radiation source 400. When capturing a radiographic image of a subject, the radiation imaging apparatus 100 is installed at a position where the radiation emitted from the radiation source 400 is incident after the positional relationship between the radiation source 400 and the subject is adjusted. The installation may be automatically controlled by a manual operation by the operator and the control device 200 based on the positional relationship between the radiation source 400, the subject, and the radiation imaging apparatus 100. The radiation imaging apparatus 100 transmits the acquired radiation image data to the control apparatus 200 by wireless communication. The control device 200 performs image processing on the received radiation image data, and causes the display device (not shown) to display the radiation image data after the image processing. The operator can determine the success or failure of imaging based on the radiation image (radiation image data after image processing) displayed on the display device.

  Next, the radiation imaging apparatus 100 in the first embodiment will be described with reference to FIG. FIG. 2A is a perspective view showing the radiation imaging apparatus 100 in the present embodiment. FIG. 2B is a diagram showing an AA cross section in FIG.

  The radiation imaging apparatus 100 includes a radiation detection panel 1 for converting radiation into an electrical signal. The radiation detection panel 1 has a function of converting incident radiation into an electrical signal. The radiation detection panel 1 includes a sensor substrate 1c in which a plurality of photoelectric conversion elements are two-dimensionally disposed on a glass substrate, a phosphor layer 1a disposed on the sensor substrate 1c, and a phosphor layer 1a. It is comprised from the arrange | positioned fluorescent substance protective film 1b. As the plurality of photoelectric conversion elements arranged on the sensor substrate 1c, conversion elements capable of detecting MIS type and PIN type visible light are used. The phosphor protective film 1b is made of a material having a relatively high moisture resistance and is used to protect the phosphor layer 1a. With the above-described configuration, in the radiation detection panel 1, the phosphor layer 1a emits light by incident radiation, and the photoelectric conversion element disposed on the sensor substrate 1c converts the emitted light into an electrical signal. The radiation detection panel 1 may use a direct conversion type conversion element that directly converts radiation into an electrical signal, instead of the phosphor layer 1a and the photoelectric conversion element.

  The radiation detection panel 1 is electrically connected to the control board 5 via the flexible circuit board 4. The control board 5 reads the electrical signal converted by the radiation detection panel 1 and processes the read electrical signal. The control board 5 converts the electrical signal into a digital signal and acquires radiation image data.

  The support base 6 supports the radiation detection panel 1 on the radiation incident side. The support base 6 supports the control substrate 5 on a surface facing the surface that supports the radiation detection panel 1. Further, the radiation imaging apparatus 100 includes a buffer material 3 that protects the radiation detection panel 1 from an external force between the housing 7 and the radiation detection panel 1.

  The housing 7 accommodates the radiation detection panel 1, the buffer material 3, the control board 5, and the support base 6. The housing 7 has a substantially rectangular parallelepiped shape composed of a plurality of surfaces. The housing 7 has an incident surface 7a on which radiation is incident, a back surface 7b disposed at a position facing the incident surface 7a across the radiation detection panel 1, and a plurality of side surfaces 7c that connect the incident surface 7a and the back surface 7b. doing.

  The incident surface 7a preferably has a relatively high radiation transmittance in order to allow radiation to enter. Furthermore, it is preferable that the incident surface 7a is light in weight and can secure a certain strength against an impact. Therefore, for example, a resin material or CFRP (carbon fiber reinforced plastic) is used for the incident surface 7a. The incident surface 7a has a substantially flat structure in order to reduce a sense of discomfort given to the subject when directly in contact with the subject's body. Here, “substantially flat” includes not only a completely flat structure but also a slight error due to manufacturing or the like.

  It is preferable that the back surface 7b and the side surface 7c are ensured to have strength against dropping, impact, etc., light weight for the purpose of reducing the burden during transportation, and high operability. For example, a metal alloy such as magnesium or aluminum, CFRP, fiber reinforced resin, or the like is used. Moreover, in order to reduce effectively the noise received from the exterior of the housing 7, you may use the material with comparatively high magnetic permeability, such as SUS430.

  Furthermore, the radiation imaging apparatus 100 includes a battery 30 that supplies power to the radiation detection panel 1 and the control board 5. The radiation detection panel 1 and the control board 5 can perform an operation for imaging based on the power supply from the battery 30. As an example, the battery 30 includes a secondary battery such as a lithium ion battery or an electric double layer capacitor, and an exterior housing these. The radiation imaging apparatus 100 can perform radio imaging operation by supplying power from the battery 30 and improve portability.

  Here, in the state where the battery 30 is mounted, the outer surface of the battery 30 and the back surface 7b of the housing 7 are substantially flat. Here, “substantially flat” includes not only a completely flat structure but also a slight error due to manufacturing or the like. For this reason, even if it is a case where it arrange | positions in the clearance gap between the subject and the bed of the sleeping state, it becomes the structure which does not give a strange feeling to a subject.

  Next, the structure of the back surface portion of the radiation imaging apparatus 100 will be described with reference to FIG. FIGS. 3A and 3B are views of the radiation imaging apparatus 100 as viewed from the side opposite to the radiation incident side (hereinafter referred to as the back side). First, the structure of a housing is demonstrated using Fig.3 (a).

  The housing 7 is provided on the back surface 7b and includes a mounting portion 40 for mounting the battery 30 in a detachable manner. Furthermore, the radiation imaging apparatus 100 includes an operation unit 5 that unlocks the battery 30 attached to the attachment unit 40. The operator can unlock the battery 30 and remove the battery 30 by performing one predetermined operation on the operation unit 5 on the same plane as the back surface 7b. In other words, the operation unit 5 releases the lock by displacing in one predetermined direction on the same plane as the back surface 7b.

  An arrow z in FIG. 3A indicates the direction in which the operation unit 5 can be displaced. A line segment x and a line segment y indicate the lengths of the perpendicular lines from the starting point in the displacement direction z of the operation unit 5 to the two side surfaces of the housing 7 close to the operation unit 5 when viewed from the back side. Here, the line segment y and the operation direction z of the operation unit 5 are parallel, and the line segment x and the operation direction z of the operation unit 5 are vertical. The arrangement of the adjacent two side surfaces among the plurality of side surfaces 7c and the operation unit 5 is defined so that the line segment y is longer than the line segment x. That is, the predetermined one displacement direction which is the displacement direction of unlocking in the operation unit 5 is one side surface of the plurality of side surfaces 7 b and is the side surface closest to the operation unit 5. It is defined to be parallel.

  For this reason, the operation unit 5 can prevent the lock from being released even if the operator's finger touches the operation unit 5 with respect to gripping the side surface 7c. In other words, the lock is released when the operation unit 5 is operated in a direction perpendicular to the side surface far from the operation unit 5 among the two adjacent side surfaces of the plurality of side surfaces 7c. For this reason, since it is prescribed that the operation unit 5 is arranged as far as possible from the gripping of the side surface 7c, it is possible to prevent the battery 30 from being unintentionally released.

  With the above configuration, the battery 30 can be prevented from being unintentionally released. In addition, it is possible to prevent the lock from being released when the radiation imaging apparatus 100 is installed on the imaging table (stand) or when it is installed between the subject and the bed. In particular, in imaging of knees and shoulders, since the subject holds the radiation imaging apparatus 100 in various postures, there is a higher possibility of causing an erroneous operation compared to other operations. For this reason, radiation irradiation is performed in a state where the battery 30 is unintentionally disconnected, and the possibility of giving unnecessary exposure to the subject can be suppressed.

  Next, the positional relationship between the grip part 19 and the operation part 5 will be described with reference to FIGS. As shown in FIGS. 3A and 3B, the housing 7 includes a grip 19 on the outer edge of the back surface 7 b for the operator to grip the housing 7. The grip 19 is a recessed portion provided on the plane of the back surface 7b. The gripper 19 allows the operator and the subject to put their fingers on when gripping the housing 7, and the operability of the radiation imaging apparatus 100 is improved. The housing 7 in FIG. 3A is seen from the back surface side, and the gripping portion 19 extends along the side surface of the outer edge of the back surface 7b that is far from the operation portion 5 among the two side surfaces close to the operation portion 5. An example is provided. In the arrangement of the grip portion 19 and the operation portion 5, if the length from the grip portion 19 to the operation portion 5 is sufficiently long, the battery 30 is unlocked unintentionally when the operator grips. Can be suppressed.

  Here, FIG. 3B is used to show an example in which the arrangement of the gripping portion 19 on the back surface 7b is different from that in FIG. Compared to FIG. 3A, the housing 7 in FIG. 3B is an extension line in the displacement direction of the side surface 7c on the side far from the operation unit 5 out of the two side surfaces close to the operation unit 5. The grip portion 19 is arranged at a position different from the above. For this reason, it is possible to prevent the battery 30 from being unintentionally released when the operator puts his / her finger on the grip 19 and grips the housing 7. Here, the length of the finger of the human hand, in particular, the length of the middle finger is generally about 100 mm. For this reason, the configuration of FIG. 3A can effectively prevent the battery 30 from being unlocked unintentionally when the length of the line segment y exceeds 100 mm. On the other hand, when the length of the line segment y is less than 100 mm, the operation unit 5 may be unintentionally unlocked. Therefore, the arrangement of the operation unit 5 and the gripping unit 19 is preferably configured as shown in FIG. Alternatively, as shown in FIGS. 5 and 6, which will be described later, the operation unit 5 and the grip unit 19 are arranged by operating in a direction away from the side surface far from the operation unit 5 out of the two adjacent side surfaces. It is preferable to be configured to be unlocked.

  The lock mechanism of the battery 30 in this embodiment will be described with reference to FIG. FIG. 4A is a cross-sectional view of the radiation imaging apparatus 100 and shows a peripheral portion of the battery 30 attached to the attachment portion 40. FIG. 4B is a plan view of the radiation imaging apparatus 100 viewed from the back side, and is a view showing a peripheral portion of the battery 30. 4 and 5 each show an example in which the operation unit 5 is configured on the housing 7 side, and FIG. 6 illustrates an example in which the operation unit 5 is configured on the battery 30 side.

  The radiographic apparatus 100 in FIG. 4 includes a guide unit 9. The guide portion 9 is disposed on the back surface 7 b of the housing 7 and in a recess provided at a position adjacent to the mounting portion 40. The guide unit 9 assists the movement of the operation unit 5 in the Z direction and defines the arrangement of the operation unit 5. For example, the guide unit 9 is configured by a linear guide or the like. Further, the guide unit 9 has a function of defining the arrangement of the operation unit 5 on the guide unit 9. The guide unit 9 may include a magnet between the operation unit 5 and the arrangement of the operation unit 5 and the guide unit 9 may be held by a magnetic force. Moreover, it is good also as a structure which arrange | positions a catch mechanism between the operation part 5 and the guide part 9, and hold | maintains arrangement | positioning of the operation part 5 and the guide part 9 mechanically. With this configuration, the operation unit 5 can move displaceably between a storage position where the battery 30 is locked and a release position where the battery 30 is unlocked. Further, the operation unit 5 is movable by sliding on the guide unit 9 and is displaced by an operation in a predetermined direction by the operator. Here, the storage position indicates the position of the operation unit 5 when the operation unit 5 and the battery 30 are engaged. The release position indicates the position of the operation unit 5 when the operation unit 5 and the battery 30 are disengaged. The operation unit 5 can be locked so that the battery 30 is not detached from the mounting unit 40 by being disposed at the storage position.

  First, the case where the battery 30 is locked to the mounting portion 40 will be described. The battery 30 includes a recess 31 for engaging with the housing 7 and a recess 32 for engaging with the operation unit 5. The operation unit 5 has a protrusion 41. In a state where the battery 30 is mounted on the mounting portion 40, the protrusion 42 of the housing 7 and the recess 32 at the bottom of the battery 30 are engaged. In this case, the operation unit 5 is disposed at the release position. And if the operation part 5 moves to a storage position, the protrusion part 41 will engage with the hollow 31 of the battery 30. FIG. In this state, the battery 30 is locked with respect to the housing 7. Thus, the battery 30 attached to the attachment part 40 is securely locked by the structure of the operation part 5 and the housing 7. Next, a case where the lock of the battery 30 is released will be described. The operation unit 5 is arranged at the release position by moving upward in FIG. By disposing the operation unit 5 at the unlock position, the engagement between the protrusion 41 of the operation unit 5 and the recess 31 of the battery 30 is released. The battery 30 can be removed from the mounting portion 40.

  Next, the radiation imaging apparatus 100 in FIG. 5 will be described. The radiation imaging apparatus 100 in FIG. 5 has a structure in which the battery 30 is taken out by moving the operation unit 5 in a direction away from the side surface 7 c of the housing 7.

  The battery 30 includes the convex portion 10. The convex portion 10 has a structure in which a compression spring (not shown) is formed at a connection portion with the battery 30 and is recessed in the battery 30 when a predetermined external force is applied from the operation portion 5. As shown in FIG. 5, the battery 30 is locked to the mounting portion 40 when the convex portion 10 engages with the claw portion 11. Further, when removing the battery 30, the tip of the operation unit 5 applies a force in a direction to remove the battery 30 from the mounting unit 40 by moving the operation unit 5 downward in the drawing. The battery 30 is unlocked when the convex portion 10 is positioned outside the claw portion 11. A tension spring 12 is formed between the operation unit 5 and the housing 7, and the operation unit 5 is displaced so as to release the lock of the battery 30, and then is moved to the storage position in the upward direction by the force of the tension spring 12. Move the slide. Thereby, the battery 30 is accommodated without interfering with the operation unit 5 when mounted on the mounting unit 40. The convex portion 10 may be configured on the radiation imaging apparatus 100 side, and the claw portion 11 may be configured on the battery 30 side.

  Next, the radiation imaging apparatus 100 in FIG. 6 will be described. 4 differs from FIG. 4 in that the guide unit 9 and the operation unit 5 are arranged on the battery 30 side.

  In the radiation imaging apparatus 100 in FIG. 6, a compression spring 14 is configured between the operation unit 5 and the battery 30. The battery 30 is locked with respect to the mounting portion 40 in a state where the upper end portion of the operation portion 5 is engaged with the inside of the claw portion 13. And the operation part 5 is disengaged from the convex part 13 by displacing to the release position (downward in FIG. 6). The operator can remove the battery 30 in a state in which the engagement between the operation unit 5 and the convex portion 13 is released. When the battery 30 is attached to the attachment portion 40, the inclination 51 of the operation portion 5 comes into contact with the convex portion 13, so that the compression spring 14 of the operation portion 5 moves downward due to the reaction force due to the reaction with the housing 7. Is pushed into. Further, when the battery 30 is stored in the housing 7, the operation portion 5 moves upward by the force of the compression spring 14. The battery 30 is held by the housing 7 by the operation unit 5 engaging the convex portion 13.

  5 and 6, the operation unit 5 acts so that the battery 30 is locked by being displaced in a direction approaching the side surface on the far side of the two adjacent side surfaces of the housing 7. . For this reason, it is suppressed that the finger | toe which the operator hold | gripped the housing 7 contacts the operation part 5, and the operation part 5 cancels | releases holding | maintenance unintentionally by an operator's operation | movement or the own weight of the radiography apparatus 100. obtain.

  4 and 5, the battery 30 can be locked without a special mechanism other than the recess. Therefore, a general-purpose battery is selected as the battery 30. Further, when the operation unit 5 is configured on the battery 30 side as shown in FIG. 6, the battery 30 can be replaced without replacing the housing 7 even if a malfunction occurs in the operation unit 5. It is possible to cope with.

(Second embodiment)
A radiation imaging apparatus according to the second embodiment will be described with reference to FIGS. The radiation imaging apparatus 500 according to the present embodiment includes a cover portion 15 that is arranged so as to cover the battery 30 on the plane of the back surface 7b of the housing 7, and the cover portion 15 is configured to be detachable from the housing. Yes.

  FIG. 7A is a diagram of the radiation imaging apparatus 500 viewed from the back. FIG. 7B is a cross-sectional view of the radiation imaging apparatus 500 and shows a peripheral portion of the battery. FIG. 7C is a view of the radiation imaging apparatus 500 viewed from the back side, and is a view showing a peripheral portion of the battery 70 attached to the attachment portion 80.

  The radiation imaging apparatus 500 includes a cover unit 15. The cover portion 15 protects the battery 70 from external force and suppresses water from flowing into the battery 70 from the outside of the housing 7. The cover unit 15 is configured to be detachable from the radiation imaging apparatus 500. The attaching / detaching operation of the cover unit 15 is performed by operating the operation unit 5 in a predetermined one direction, like the battery 70 in the first embodiment. That is, the cover portion 15 can be removed when the operation portion 5 is displaced in one predetermined direction.

  The radiation imaging apparatus 500 locks the cover unit 15 and holds the battery 70 disposed inside the cover unit 15. For this reason, it can be said that the cover portion 15 indirectly locks the battery 70 attached to the attachment portion 80. The battery 70 is disposed in the radiation imaging apparatus 500 in a state covered with the cover unit 15. Here, the surface formed by the back surface 7b of the housing 7 and the outer wall of the cover portion 15 has a substantially flat shape. Here, “substantially flat” includes not only a completely flat structure but also a slight error due to manufacturing or the like.

  The attaching / detaching mechanism of the cover portion 15 will be described with reference to FIGS. 7B and 7C. 7B and 7C, the operation unit 5 is disposed on the cover unit 15. The cover part 15 in FIGS. 7B and 7C includes the operation part 5 and the compression spring 14. The cover portion 15 has a recess 81 for engaging with the housing 7. In a state where the cover portion 15 is mounted on the housing 7, the protruding portion 82 of the housing 7 and the recess 81 of the cover portion 15 are engaged. The cover portion 15 is locked to the housing 7 in a state where the end of the operation portion 5 is engaged with the convex portion 13 of the housing 7. The operation portion 5 is moved downward in FIG. 7 to release the engagement with the convex portion 13. Then, the operator can remove the cover portion 15 in a state where the engagement between the operation portion 5 and the convex portion 13 is released. The battery 30 can also be attached and detached in accordance with the operation direction of unlocking the cover portion 15. When the cover portion 15 is mounted on the back surface 7b of the housing 7, the operation portion 5 is shown by the force applied to the housing 7 because the tip portion with the taper of the operation portion 5 contacts the outside of the convex portion 13. Move down in 7. Further, when the cover portion 15 is stored in the housing 7, the operation portion 5 is moved upward by the force of the compression spring 14. Then, the operating portion 5 is engaged with the convex portion 13, whereby the cover portion 15 is locked to the housing 7.

  With the above-described structure, the radiation imaging apparatus 500 can improve protection from the external force applied to the battery by the cover unit 15 and waterproof performance while suppressing erroneous operation of the operation unit 5 as in the first embodiment.

  Next, the attachment / detachment mechanism for the battery 70 and the cover unit 15 from the radiation imaging apparatus 500 will be described with reference to FIG. FIG. 8 is a perspective view from the back side of the radiation imaging apparatus 500. Here, FIG. 8A is a diagram regarding the removal of the cover portion 15, and FIG. 8B is a diagram regarding the removal of the battery 70.

In a state where the lock by the operation of the operation unit 5 is released, the cover unit 15 rotates about the shaft 16 including the engaged portion and is detached from the radiation imaging apparatus 500. In FIG. 8B, the battery 70 is engaged with the radiation imaging apparatus 500 on a side perpendicular to the shaft 16 (a side that is not parallel). The battery 70 is removed from the radiation imaging apparatus 500 by rotating around the shaft 17 after the cover 15 is removed. The battery 70 may be configured to rotate toward the side near the side surface of the housing 7. In this case, since the distance between the adjacent side surfaces of the battery 70 is shortened, damage due to dropping when the battery 70 is attached or detached can be suppressed.

  FIG. 9 is a view showing an engaging portion where the cover portion 15 and the housing 7 are engaged. Here, FIG. 9A shows a state where the cover unit 15 is closed with respect to the radiation imaging apparatus 500. FIG. 9B shows a state where the cover unit 15 is opened with respect to the radiation imaging apparatus 500. The cover unit 15 and the battery 70 can be detached from the mounting unit 80 by rotating one side of the outer edge of the mounting unit 80 as a rotation center axis in a state where the lock is released by the operation unit 5. FIG. 9A rotates using the catch between the cover portion 15 and the housing 7. FIG. 9B rotates using the catch between the battery 70 and the housing 7. In addition, when the axis | shaft 16 exists in the upper part of the battery 70, the rotation of the battery 70 is attained by opening at least 90 degrees or more from the state which closed the cover part 15.

  FIG. 10 is a view showing an engaging portion where the cover portion 15 and the housing 7 are engaged. FIGS. 10A and 10B are cross-sectional views of the radiation imaging apparatus 500, each showing the periphery of the battery 70. FIG. FIG. 10 shows an example where the cover portion 15 and the housing 7 are not separated. Here, FIG. 10A shows a state where the cover unit 15 is closed with respect to the radiation imaging apparatus 500. FIG. 10B shows a state where the cover unit 15 is opened with respect to the radiation imaging apparatus 500.

  In FIG. 10, the cover portion 15 is rotated by a hinge 18. When the hinge 18 is configured, the rotation axis of the hinge 18 and the axis 16 coincide. In order to remove the cover portion 15, the hinge 18 may be separable on the cover portion 15 side and the radiation imaging apparatus 500 side.

  With the above configuration, the cover unit 15 and the battery 70 are configured so that one side of each outer shape is pivoted and the respective axes are not parallel to each other, so that the battery 70 is not intended when the cover unit 15 is opened and closed. It can suppress falling off.

  As mentioned above, although it explained in full detail based on embodiment, it is not restricted to these specific embodiment, Various forms of the range which does not deviate from the summary of invention are also included in the category of this invention.
