Japanese Patent Laid-Open No. 2003-14862 (page 3, FIG. 7)

  However, the conventional radiation detection apparatus has the following problems. In other words, when the support member and the radiation detector are bonded with an adhesive, it is not easy to accurately align the positions of the support member and the radiation detector. Also, once bonded, it is not easy to remove and takes time. That is, there is a problem that when the support member and the radiation detector are bonded together by the adhesive, assembly and removal cannot be easily performed.

  The present invention has been made in view of such circumstances, and a radiation detector that can easily assemble and fix a radiation detector inside the housing of the radiation detector and can be easily removed. An object is to provide a detection device.

In order to achieve such an object, the present invention has the following configuration.
Specifically, the device of the radiation detection apparatus according to claim 1 is (A) a radiation detector that detects radiation by converting it into an electrical signal, (B) an internal cavity housing having an open portion, and (C). And (D) a part or all of an arbitrary first surface of the radiation detector is connected to the lid via at least a non-adhesive elastic member, and (E) ) A part or all of the second surface facing the first surface of the radiation detector is connected to the inside of the housing via at least a non-adhesive elastic member, and (F) the second surface of the radiation detector A part or all of the surfaces other than the first surface and the second surface are connected to the inside of the housing through at least an elastic member.

[Operation / Effect] The operation of the device of claim 1 is as follows.
First, the lid that covers the open part of the housing of the radiation detection apparatus is opened. Next, a part or all of the surfaces other than the first surface of the radiation detector (for example, the surface on which the radiation of the radiation detector is incident) and the second surface (the surface facing the first surface) are elastic. An elastic member is disposed at a position where the inside of the housing can be connected via the member. Further, the non-adhesive elastic member is disposed at a position where a part or all of the second surface of the radiation detector can be connected to the inside of the housing via the non-adhesive elastic member. Furthermore, a radiation detector for converting radiation into an electrical signal and detecting it is placed on the non-adhesive elastic member. Here, a part or all of the surfaces other than the first surface and the second surface of the radiation detector are connected to the inside of the housing via the elastic member. Furthermore, a non-adhesive elastic member is disposed on the radiation detector. That is, the non-adhesive elastic member is disposed at a position where a part or all of the first surface of the radiation detector can be connected to the lid of the housing via the non-adhesive elastic member. Here, since the elastic member is non-adhesive, for example, when the non-adhesive elastic member is connected to the first surface and the second surface of the radiation detector, the non-adhesive elastic member is used. Even if the member and the first and second surfaces of the radiation detector do not stick to each other and cannot be disposed at an accurate position at one time, the interior of the housing is maintained until it can be disposed at an accurate position. The position is adjusted by moving the radiation detector and the non-adhesive elastic member. Further, after the radiation detector and the non-adhesive elastic member are disposed at the correct positions, the lid that covers the opening of the housing is closed.

  That is, in the up-down direction (the direction in which the first surface and the second surface of the radiation detector face each other) within the housing of the radiation detection device, the housing lid, the non-adhesive elastic member, the radiation detector, The radiation elastic detector is fixed in the order of the adhesive elastic member and the inside of the housing. Further, in the left-right direction, the inside of the housing, the elastic member, the radiation detector, the elastic member, and the inside of the housing are arranged in this order, and the radiation detector is fixed. Therefore, it does not move in any direction of up, down, left and right, and is in a fixed state.

  Therefore, the assembly of the radiation detector inside the housing of the radiation detection device is performed in a non-adhesive elasticity in the direction in which the first surface and the second surface of the radiation detector face each other inside the housing of the radiation detection device. Each of the member, radiation detector, and non-adhesive elastic member is arranged in order, and the elastic member is non-adhesive, so it does not stick to the radiation detector inside the housing, but inside the housing , The radiation detector and the elastic member can be moved, and these can be easily adjusted to an accurate position. Furthermore, an elastic member is disposed between the inside of the housing of the radiation detection apparatus (other than the direction in which the first surface and the second surface of the radiation detector face each other) and the radiation detector, and an open portion of the housing The radiation detector can be fixed inside the housing of the radiation detection device only by assembling with a lid. That is, the radiation detector can be easily assembled and fixed inside the housing of the radiation detection apparatus. In addition, when removing the radiation detector from the inside of the housing of the radiation detection device, since the elastic member is non-adhesive, it is fixed in a state where it is not adhered to the radiation detector inside the housing, Can be easily removed.

  The invention of claim 2 is the radiation detection apparatus according to claim 1, further comprising a support member for supporting the radiation detector, wherein the support member includes a second surface of the radiation detector and the housing. It is provided between a non-adhesive elastic member interposed between the inside and the inside of the housing.

  [Operation / Effect] According to the invention of claim 2, the support member for supporting the radiation detector includes a non-adhesive elastic member interposed between the second surface of the radiation detector and the inside of the housing, and the inside of the housing. Therefore, even when the strength of the radiation detector alone is weak in the bending direction, the strength can be maintained by the support member, and the radiation detector can be prevented from being damaged.

  The invention of claim 3 is the radiation detection apparatus according to claim 1 or 2, wherein the non-adhesive elastic member is conductive.

  [Operation / Effect] According to the invention of claim 3, the non-adhesive elastic member is conductive. Therefore, unnecessary static electricity accumulated in the radiation detector can be removed via the non-adhesive elastic member. That is, in the detection by the radiation detector, the influence of this static electricity can be removed and the input of electrical noise can be reduced.

  The invention of claim 4 is characterized in that the elastic member according to any one of claims 1 to 3 is a gel-like material having silicone as a main material.

  [Operation / Effect] According to the invention of claim 4, the elastic member is a gel-like material mainly composed of silicone. Therefore, when the radiation detector is assembled in the housing of the radiation detection apparatus, the impact on the radiation detector can be absorbed, and the radiation detector can be further prevented from being damaged.

  According to the present invention, the assembly of the radiation detector inside the housing of the radiation detector is performed in the direction in which the first surface and the second surface of the radiation detector face each other inside the housing of the radiation detector. Each of the non-adhesive elastic member, the radiation detector, and the non-adhesive elastic member is arranged in order, and since the elastic member is non-adhesive, it does not stick to the radiation detector inside the housing. The radiation detector and the elastic member can be moved inside the casing, and these can be easily adjusted to an accurate position. Further, an elastic member is disposed between the inside of the housing of the radiation detection apparatus (other than the direction in which the first surface and the second surface of the radiation detector face each other) and the radiation detector, and an open portion of the housing The radiation detector can be fixed inside the housing of the radiation detection device by only assembling with a lid. That is, the radiation detector can be easily assembled and fixed inside the housing of the radiation detection apparatus. In addition, when removing the radiation detector from the inside of the housing of the radiation detection device, since the elastic member is non-adhesive, it is fixed in a state where it is not adhered to the radiation detector inside the housing, Can be easily removed.

  The radiation detection apparatus will be described in detail with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing the overall configuration of the radiation detection apparatus. FIG. 2 is a schematic plan view showing the configuration of the radiation detector and the positioning member. FIG. 3 is a block diagram showing the configuration of the flat panel X-ray detector as viewed from the side. FIG. 4 is a block diagram showing the configuration of the flat panel X-ray detector in plan view.

  The overall configuration of the radiation detection apparatus will be described with reference to FIG. As shown in FIG. 1, a support member 2 is attached to a support member attaching portion 1 c inside the housing 1 of the radiation detection apparatus, and a non-adhesive elastic member 3 a and a radiation detector are mounted on the support member 2. 4. Non-adhesive elastic member 3b is placed in order. Further, a positioning member 5 is attached to the support member 2, and an elastic member 6 is sandwiched between the positioning member 5 and the non-adhesive elastic member 3a, the radiation detector 4, and the non-adhesive elastic member 3b. The elastic member 6 is disposed at four corners of the radiation detector 4 as shown in FIG. In addition, let the 1st surface of a radiation detector be the surface by which the radiation of the radiation detector 4 is incident, for example, and let the 2nd surface be a surface facing a 1st surface. Details of these configurations will be described below.

  First, the electrical configuration of the radiation detector 4 will be described. For example, the radiation detector 4 may be a direct conversion type flat panel radiation detector that changes incident radiation directly into charge information. As shown in FIGS. 1 and 3, the direct conversion type flat panel radiation detector has a radiation conversion layer 4b that detects incident radiation and converts it into charge information, and the radiation conversion layer 4b detects the radiation. And an active matrix substrate 4a that collects (electrically reads out) the generated charge information.

  The radiation conversion layer 4b is provided with a radiation sensitive semiconductor, and the radiation sensitive semiconductor is, for example, amorphous selenium (a-Se) or the like, and is amorphous on the carrier collection electrode 7 as shown in FIG. -Selenium is laminated. When radiation (X-rays) is incident on the radiation-sensitive semiconductor, a predetermined number of carriers (charge signals) proportional to the energy of the X-rays are directly generated, and a high voltage is applied to the radiation-sensitive semiconductor. The carrier is collected by the carrier collecting electrode 7 shown in FIG.

  The active matrix substrate 4 a includes a glass substrate 8 and a thin film transistor 9 formed on the glass substrate 8. As shown in FIGS. 3 and 4, the thin film transistor 9 includes a large number (for example, 2880 × 2880) of switching elements 10 arranged in a vertical and horizontal two-dimensional matrix. Switching elements 10 are separated from each other every seven.

  Further, as shown in FIGS. 3 and 4, the carrier collection electrode 7 is connected to the source S of the switching element 10. A plurality of gate bus lines 12 are connected from the gate driver 11, and each gate bus line 12 is connected to the gate G of the switching element 10. On the other hand, as shown in FIG. 4, a plurality of data bus lines 15 are connected via an amplifier 14 to a multiplexer 13 that collects charge signals and outputs them to one, as shown in FIGS. Thus, each data bus line 15 is connected to the drain D of the switching element 10.

  With the bias voltage applied to the common electrode (not shown), the gate of the switching element 10 is turned on by applying the voltage of the gate bus line 12 (or 0 V), and the carrier collecting electrode 7 is on the detection surface side. The charge signal converted through the X-ray sensitive semiconductor 25 from the incident X-ray is read out to the data bus line 15 through the source S and drain D of the switching element 10. Until the switching element 10 is turned on, the charge signal is provisionally accumulated and stored in a capacitor (not shown). The charge signal read out to each data bus line 15 is amplified by the amplifier 14. Further, the signal is combined into one charge signal by the multiplexer 13, digitized by the A / D converter 16, and output as an X-ray detection signal.

  Furthermore, the mechanism for the radiation detector 4 will be described. As shown in FIG. 1, the radiation detector 4 includes an active matrix substrate 4a at the bottom, a radiation conversion layer 4b thereon, and a glass plate 4c for sealing the radiation conversion layer 4b. As shown in FIG. 2, the active matrix substrate 4a is a square that is slightly larger than the radiation conversion layer 4b, and the radiation conversion layer 4b has a size of, for example, 17 inches × 17 inches. The thicknesses of the active matrix substrate 4a, the radiation conversion layer 4b, and the glass plate 4c are, for example, 0.7 mm.

  Next, the support member 2 will be described. The support member 2 is used for giving strength when the radiation detector 4 is housed in the housing 1 of the radiation detection apparatus. The size of the support member 2 is the same as that of the active matrix substrate 4a of the radiation detector 4, the thickness is 5 mm, for example, and the material is a metal such as aluminum or a resin. The support member 2 is fixed by a screw N at a support member mounting portion 1 c of the housing 1.

  Further, the support member 2 includes positioning members at positions corresponding to the four corners of the active matrix substrate 4a of the radiation detector 4, which is the position shown in FIG. 2 (the support member 2 is on the back side of the active matrix substrate 4a). 5 is attached. Further, as shown in FIG. 1, the positioning member 5 is in a state of being placed on the support member mounting portion 1 c, and the radiation sensitivity of the radiation detector 4 is determined from the position of the surface attached to the support member mounting portion 1 c of the support member 2. There is a height up to the type semiconductor, and it is L-shaped. Further, in the portion corresponding to the height at which the non-adhesive elastic member 3a and the radiation detector 4 are disposed, which is a recessed portion of the L-shaped positioning member 5, for example, a gel mainly made of silicone is used. An elastic member 6 made of a material is provided. That is, a part (four corners) of the surface other than the first surface and the second surface of the radiation detector 4 is connected to the support member mounting portion 1 c inside the housing 1 via the elastic member 6. Yes. Therefore, the radiation detector 4 and the non-adhesive elastic member 3a are in a state where they do not move left and right. Further, since the radiation detector 4 is not in direct contact with metal or the like but in contact with the elastic member 6, the radiation detector 4 is protected by the elastic member 6, and the radiation detector 4 is damaged. It is the structure which prevents that.

  The non-adhesive elastic members 3a and 3b are non-adhesive, that is, elastic members that do not adhere to other materials. For example, sponge, cloth, urethane resin, or the like is used, and the size of the non-adhesive elastic member 3a is The size is the same as that of the active matrix substrate 4a of the radiation detector 4, the size of the non-adhesive elastic member 3b is substantially the same size as the inside of the housing 1, and the thickness of each is, for example, 1 mm. For example, the non-adhesive elastic member 3a is disposed so as to abut on the entire second surface of the radiation detector 4 (active matrix substrate 4a), and the non-adhesive elastic member 3b is provided with the radiation detector 4 ( The glass plate 4c) is disposed so as to be in contact with the entire first surface. When arranged in this way, the radiation detector 4 is not in direct contact with metal, but is in contact with the non-adhesive elastic members 3a and 3b. It is the state protected by the elastic elastic members 3a and 3b, and is configured to prevent the radiation detector 4 from being damaged.

  The internal cavity of the housing 1 of the radiation detection apparatus has a size that can accommodate the radiation detector 4, the support member 2, the non-adhesive elastic members 3 a and 3 b, the elastic member 6, and the like. Moreover, the cover 1a which covers the open part of the housing | casing 1 and the baseplate 1b which comprises the surface facing an open part have the structure which can be removed. For example, the lid 1a is made of a carbon resin having a thickness of 1 mm, and the lid 1a and the non-adhesive elastic member 3b are connected to each other by fastening the lid 1a to the housing 1 with screws N. That is, by closing the lid 1a of the housing 1, the radiation detector 4 is sandwiched between the lid 1a and the support member 2 and is not movable in the vertical direction.

  Next, a procedure for assembling the radiation detection apparatus will be described. The positioning members 5 are attached in advance to the four corners of the support member 2, and the elastic members 6 made of a gel material mainly made of silicone are attached to the positioning members 5.

  Next, the lid 1 a and the bottom plate 1 b of the housing 1 of the radiation detection apparatus are removed, and the support member 2 is attached to the support member attaching portion 1 c of the housing 1. Thereafter, the bottom plate 1b of the housing 1 is attached. Next, the non-adhesive elastic member 3 a is placed on the support member 2. Further, the radiation detector 4 and the non-adhesive elastic member 3b are placed in this order. Here, the non-adhesive elastic member 3 a, the radiation detector 4, and the non-adhesive elastic member 3 b are disposed at predetermined positions in the housing 1. Here, the non-adhesive elastic members 3a and 3b are non-adhesive. That is, the non-adhesive elastic members 3a and 3b do not adhere to the radiation detector 4 inside the housing 1, and if they cannot be disposed at an accurate position at one time, the housing is not disposed until it can be disposed at an accurate position. Positioning is performed by moving the radiation detector 4 and the non-adhesive elastic members 3a and 3b inside the body 1.

  When the radiation detector 4 is placed on the non-adhesive elastic member 3a, the surfaces other than the first surface and the second surface of the radiation detector 4 (active matrix substrate 4a) are in contact with the elastic member 6. It becomes a state. Here, since the thickness of the active matrix substrate 4a (the direction in which the first surface and the second surface face each other) is as thin as, for example, 0.7 mm as described above, the active matrix substrate 4a is in contact with the elastic member 6. The portion is small, and therefore on a wide surface such as the surface of the active matrix substrate 4a which is the second surface of the radiation detector 4 (the size of the radiation conversion layer 4b, for example, a size slightly larger than 17 inches × 17 inches). There is no problem caused by the adhesion between the radiation detector 4 and the elastic member 6 in alignment for placement. That is, even if the elastic member 6 that is in contact with the surface other than the first surface and the second surface of the radiation detector 4 (active matrix substrate 4a) is sticky, it cannot be moved to be disposed at an accurate position. Easy. Further, after the radiation detector 4 and the non-adhesive elastic members 3a and 3b are arranged at accurate positions, the opening portion of the housing 1 of the radiation detection device is closed by the lid 1a, thereby assembling the radiation detection device. Is completed.

  The procedure for taking out the radiation detector 4 is the reverse of the above operation, that is, the lid 1a of the housing 1 of the radiation detection device is opened, the non-adhesive elastic member 3b is taken out, and then the radiation detector 4 is taken out. .

  As described above, according to the radiation detection apparatus, the elastic member 6 is disposed between the positioning member 5 attached to the support member 2 and the radiation detector 4, and the support member is attached inside the housing 1 of the radiation detection apparatus. The non-adhesive elastic member 3a, the radiation detector 4, and the non-adhesive elastic member 3b are sequentially placed on the support member 2 attached to the portion 1c, and the non-adhesive elastic member is placed at a predetermined position inside the housing 1. Each of 3a, radiation detector 4, and non-adhesive elastic member 3b is disposed. Here, since the non-adhesive elastic members 3a and 3b are non-adhesive, the non-adhesive elastic members 3a and 3b are not in a state of being adhered to the radiation detector 4 inside the housing 1, but the housing 1 The radiation detector 4 and the non-adhesive elastic members 3a and 3b can be moved inside, and these can be easily adjusted to an accurate position. Further, an elastic member 6 is disposed between the inside of the housing 1 of the radiation detection apparatus (other than the direction in which the first surface and the second surface of the radiation detector 4 face each other) and the radiation detector 4. The radiation detector 4 can be fixed inside the housing 1 of the radiation detection apparatus 4 by assembling only by closing the open part of the body 1 with the lid 1a. That is, the radiation detector can be easily assembled and fixed inside the housing 1 of the radiation detection apparatus. Further, when the radiation detector 4 is removed from the inside of the housing 1 of the radiation detector, the non-adhesive elastic members 3a and 3b are non-adhesive. The elastic elastic members 3a and 3b are fixed in a state where they are not adhered and can be easily removed. Further, since the radiation detector 4 is not in direct contact with metal or the like and is in contact with the non-adhesive elastic members 3a and 3b and the elastic member 6, the radiation detector 4 is in the non-adhesive elastic members 3a and 3b. The state is protected by the elastic member 6. Therefore, the radiation detector 4 can be fixed in a state in which the radiation detector 4 is prevented from being damaged inside the housing 1 of the radiation detection apparatus.

  In addition, a non-adhesive elastic member 3a in which the support member 2 that supports the radiation detector 4 is interposed between the second surface of the radiation detector 4 and the support member attachment portion 1c inside the housing 1, and a support member attachment portion 1c, the radiation detector 4 alone can maintain the strength by the support member 2 even when the strength in the bending direction is weak, and can prevent the radiation detector 4 from being damaged. it can.

  Further, since the elastic member 6 is a gel material made mainly of silicone, when the radiation detector 4 is assembled in the housing 1 of the radiation detection device, the impact on the radiation detector 4 is absorbed. Thus, it is possible to prevent the radiation detector 4 from being damaged.

Therefore, the elastic member 6 is disposed inside the housing 1 of the radiation detection device, and the non-adhesive elastic member 3a and the radiation are provided from the inside of the housing 1 of the radiation detection device (the side facing the open portion of the housing 1). Since the detector 4 and the non-adhesive elastic member 3b are arranged in this order, and the radiation detector 4 can be fixed in the radiation detector by assembling only the lid 1a of the open portion of the housing 1, the radiation detector 4 can be fixed. When assembling the detection device, it is not necessary to attach the radiation detector 4 to the inside of the housing 1 with an adhesive, and it can be easily assembled.

That is, in the detection by the radiation detector 4, the influence of this static electricity can be removed and the input of electrical noise can be reduced.

  (5) In the embodiment described above, the lid 1a at the top of the housing 1 has been described as being made of a carbon resin having a thickness of 1 mm.
