    [0001] FIELD OF THE INVENTION RADIOGRAPHY APPARATUS AND RADIOGRAPHY SYSTEM BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an X-ray apparatus and to an X-ray system. State of the art X-ray devices that project radiation onto a target object and detect the intensity distribution of the radiation that has passed through the target object to obtain the radiation image of the target object are widely used. in general for non-destructive industrial examination and medical diagnosis. An imaging apparatus has recently been developed which acquires a digital image of radiation by using a radiation detection panel formed to convert, into electrical information by a sensor, light emitted in correspondence with radiation entering a scintillator. Such an imaging apparatus can instantly provide an output image. Since such an imaging apparatus can quickly image a wide range of regions, a lightweight, flat, portable imaging device has been developed called an electronic cassette. Especially in the last 25 years, to improve the transportability, we have developed a wireless imaging device that does not require a connection cable. An imaging apparatus of this type is constituted to be able to contain or connect to a rechargeable battery serving as an energy source for the power supply, and has greater transportability than a conventional imaging apparatus. At the time of imaging, the imaging apparatus could receive an impact force or other external force. A glass substrate constituting a radiation detection panel could be broken by the external force. If the glass substrate is broken, it becomes very difficult to acquire a clear radiation image. It is therefore prudent to protect the imaging apparatus satisfactorily so as to prevent breakage of the glass substrate. To implement the internal radiation detection function of the imaging apparatus even in such a situation, the imaging apparatus must take into account the mechanical strength, the vibration resistance and the impact resistance. At the same time, the imaging apparatus is required to be reduced in size, thickness, and weight in order to facilitate handling, improve transportability, and allow rapid image acquisition. For this purpose, imaging devices have various constitutions. An imaging apparatus described in Japanese Patent No. 3848288 aims for high rigidity and weight saving by supporting a radiation detection panel using a base having concave portions, and including the concave portions on the inner surface of the bottom. of a housing via a reinforcement plate and a support. An imaging apparatus disclosed in Japanese Patent Laid-open Publication No. 2010-281753 aims for high rigidity and weight saving by supporting a radiation detection panel on the bottom surface of a housing using a base and a structure thereon. An imaging apparatus disclosed in Japanese Unexamined Patent Publication No. 2012-181238 is directed to increasing the mechanical strength of the imaging apparatus by providing a casing with a monocoque structure made of a fiber reinforced resin or the like. . In the imaging apparatus described in Japanese Unexamined Patent Publication No. 2012-181238, a radiation detection panel is held by damping elements attached to two cover members which constitute the side walls of the housing. The imaging apparatus described in Japanese Unexamined Patent Publication No. 2012181238 discloses a structure in which the radiation detection panel is held by an adhesive layer on the inner wall of the top of the housing. In this way, reductions in size, thickness and weight of the imaging apparatus have been conventionally achieved by various structures. However, the prior art described above has some problems. The imaging apparatuses described in Japanese Patent No. 3848288 and in the imaging apparatus disclosed in Japanese Patent Laid-Open Publication No. 2010-281753 require a base and a support that supports a radiation detection panel, more than one box that contains the radiation detection panel. Although the imaging apparatus described in Japanese Patent Laid-Open Publication No. 2012-181238 has a structure in which the casing serving as an outer casing provides rigidity, it also requires a support member that supports the detection panel. of radiation inside the housing. The support element of the radiation detection panel may be a relatively rigid element. However, if the support member is sufficiently rigid, it becomes difficult to reduce the weight. To solve this, the rigidity is improved and by fixing the support member and the housing by a screw or the like, or by bringing them into contact. In such a case, however, it may be difficult to place a control card, a rechargeable battery and the like which must be housed in the imaging apparatus. For example, in Japanese Unexamined Patent Publication No. 2010-281753, a control board that controls the radiation detection panel is placed outside the radiation detection panel viewed in the direction of incidence of the radiation. In this case, it is difficult to employ a so-called thin framing structure that decreases the distance between the housing and the glass substrate of the imaging apparatus that protects the radiation detection panel. As a result, it becomes difficult to reduce the size of the imaging apparatus. Japanese Patent Laid-open Publication No. 2012-181238 proposes an arrangement in which a support member which supports the radiation detection panel in the housing is removed by gluing the radiation detection panel to the inner wall of the housing top on the side. the area of incidence of the radiation. In this arrangement, the necessary rigidity must be ensured at the top of the housing. Radiation emitted by a radiation source passes through a subject and the top of the housing and is then detected by the radiation detection panel. The top of the case often has a simple plate shape with an even plate thickness so that the top does not remain as an artifact in an acquired image. It is therefore difficult to improve the rigidity by changing the shape of the element, for example, by giving a ribbed structure above the housing to provide the necessary rigidity.
    [0002] To provide the necessary rigidity, the plate thickness is simply increased, and it becomes difficult to reduce the size and weight of the imaging apparatus as a whole. When the radiation detection panel is adhered to the inner surface of the top of the housing, if a load such as an external force is applied to the housing, the external force is easily transmitted to the radiation detection panel, increasing the load. In addition, when applying the external force, a high tensile stress is easily applied to the radiation detection panel due to bending stress. This tensile stress easily becomes a breakage cause of the glass substrate constituting the sensor substrate of the radiation detection panel. It is desirable to provide an advantageous radiography apparatus with respect to the protection and size reduction of a radiation detection panel. SUMMARY OF THE INVENTION According to its first aspect, the present invention provides an X-ray apparatus comprising: a radiation detection panel formed to detect radiation; an electrical component electrically connected to the radiation detection panel; and a housing formed to house the radiation detection panel, the housing including a first portion formed to allow radiation to enter the housing and irradiate the radiation detection panel, and an opposite portion, wherein the inner surface of the opposite portion includes a bearing surface 15 formed to support the radiation detection panel, wherein a portion of the outer surface of the opposite portion comprises a concave portion located at the side opposite the surface of the support, and wherein the electrical component is disposed in the concave portion. Other features of the invention will become apparent from the following description of exemplary embodiments with reference to the accompanying drawings.

DESCRIPTION OF EMBODIMENTS [First Embodiment] Figs. 1A and 1B show the exterior appearance of an X-ray apparatus (imaging apparatus) 100 which contains a radiation detection panel 1. Fig. 1A is a view showing the external appearance of the imaging apparatus 100 seen from the side of the radiation incident surface. Fig. 1B is a view showing the outward appearance of the imaging apparatus 100 seen from the side opposite the radiation incident surface side. Fig. 2 is a longitudinal sectional view showing the imaging apparatus 100 of Figs. 1A and 1B taken along the line A-A. Fig. 3 is a cross-sectional view showing the imaging apparatus 100 of Figs. and 1B taken along the line BB. In general, in the imaging apparatus 100, radiation that has been emitted by a source (not shown) of radiation and passed through a subject is detected by stored photoelectric sensors (sensors). in a two-dimensional matrix. An image acquired by the imaging apparatus 100 is transferred to the outside, displayed on a screen or the like, and used for diagnosis or the like. The radiation detection panel 1 includes a sensor substrate prepared by arranging numerous photoelectric converters (sensors) on a substrate, a scintillator layer provided on the sensor substrate, and a protective film for the scintillator layer. The radiation detection panel 1 is connected by a flexible circuit card 4. A control card 10 which reads a detection signal from the radiation detection panel 1 and processes the read detection signal is connected to the flexible circuit board 4. As shown in Fig. 2, the imaging apparatus 100 according to the first embodiment includes a rechargeable battery 2 for providing the necessary energy, but energy can be supplied from the outside by a wired connection. . The control board 5 and the rechargeable battery 2 will together be generally called the electrical components. The imaging apparatus 100 according to the first embodiment adopts the following arrangement shown in FIGS. 1A and 1B in order to achieve a reduction in weight, thickness and size. The imaging apparatus 100 is shown in FIGS. 2 and 3 as including a housing (outside) 7 which houses the radiation detection panel 1. The housing 7 includes a top 7a (hereinafter also referred to as a first portion) for causing radiation emitted by the radiation source to enter the radiation detection panel 1, a bottom 7c (also referred to as below). an opposite portion) which is placed on the opposite side to the incidence side of the radiation (i.e., the top) and which supports the radiation detection panel 1, and a side (a side wall) 7b which connects the top 7a and the bottom 7c. From the inner surface of the bottom 7c of the side facing the radiation detection panel 1, at least one bearing surface which supports the region of the useful pixels of the radiation detection panel 1 is shaped so as to be flat. The region of the useful pixels of the radiation detection panel 1 is an image forming region where a radiation image is actually acquired. The bottom 7c is placed on the opposite side to the top 7a with the radiation detection panel 1 which can be placed between them. To contain electrical components such as the control board and the rechargeable battery 2, the bottom 7c has at least one concave or recessed portion in the outer surface of the opposite side to the side facing the radiation detection panel 1. In other words, there are recesses or concave portions for containing the electrical components on the outside of the bottom portion 7c. At least one concave portion is defined by a portion of the outer surface of the bottom 7c which is accessible from the outside of the housing 7. This facilitates the use of a thin frame because no electrical component is placed at the bottom. outside (i.e., surrounding or overlapping with) the radiation detection panel 1 when viewed in the direction of incidence of the radiation (i.e., the top) . In the first embodiment, the top 7a is constituted by a different element of the side 7b and the bottom 7c, as shown in FIGS. 2 and 3. The top 7a is made of a resin reinforced with carbon fibers or the like in regard to the transmission of radiation, rigidity, and the like, but it is not limited to this. In contrast, the side 7b and the bottom 7c are made of a fiber-reinforced resin, a fiber-reinforced metal, an aluminum alloy, a magnesium alloy, or the like to provide a rigidity clean satisfactory protection of the panel 1 radiation detection. 35. The bottom 7c is made to have greater flexural rigidity than the top 7a. This can relieve the load of a tensile stress generated by a bending stress imposed on the glass substrate constituting the sensor substrate. A damper element 3 for absorbing a shock is interposed between the radiation detection panel 1 and the top 7a to protect the radiation detection panel 1 from an impact force from the radiation incident side. With this structure, the imaging apparatus 100 according to the first embodiment can provide a structure for accommodating the necessary components in the imaging apparatus 100 while obtaining the assurance of satisfactory rigidity, and a reduction in weight, thickness and size. In the first embodiment, as shown in FIGS. 2 and 3, access covers (lids) 6 intended to give the concave portion the shape of a closed space are arranged to cover the concave portions of in order to provide electrical safety, and to allow the replacement of electrical components such as the control board and the rechargeable battery 2. Each access cover 6 is fixed to the bottom 7c of the housing 7, for example, by an adjustment tight, but is removable. To guarantee the tightness of the concave part, a sealing element may be arranged at the contact portion between the bottom 7c and the access cover 6. In addition, the access covers 6 may be integrated into the control card 5 and the rechargeable battery 2 arranged in the enclosed spaces formed.
    [0003] To mitigate the influence of warping or the like caused by heat, the access cover 6 can be made of the same element or at least the same material as the bottom 7c. To promote wireless communication between the imaging apparatus 100 and the outside, the access cover 6 and. the housing 7 may be partially made of a non-conductive material. The access cover 6 may be made of a material such as a non-conductive resin, or a fiber-reinforced resin (eg, a carbon fiber reinforced resin), but is not limited to this. . The rigidity can be further improved by securing the access cover 6 to the bottom 7c, and greater weight gain can be achieved. In the first embodiment, this constitution ensures the rigidity of all the elements. While providing rigidity, and reducing weight, thickness, and size, a structure for accommodating the electrical components can be provided. A greater reduction in weight, thickness and size of the imaging apparatus 100 can be achieved, which is difficult in the prior art. [Second Embodiment] Figs. 4 and 5 are sectional views showing an imaging apparatus 100 according to the second embodiment. Figure 4 is a longitudinal sectional view taken along line A - A of Figures 1A and 1B. Figure 5 is a cross-sectional view taken along line B-B. As in the first embodiment, a control card 5 which performs a read command of a radiation detection panel 1 and the processing of an electrical output is connected to the radiation detection panel 1 via a card 4. flexible circuit, and a rechargeable battery 2 for the power supply is also arranged in the same way. In the first embodiment, the radiation detection panel 1 is supported by the bottom 7c of the housing 7 without which there is a base for supporting the radiation detection panel 1. In order to house the control board and the rechargeable battery 2 while reducing the size of the imaging apparatus 100, concave structures are formed in the bottom surface of the bottom 7c, and the access covers 6 form enclosed spaces. However, according to the first embodiment, further reducing the weight can sometimes be difficult because the housing 7 must provide the necessary rigidity for the imaging apparatus 100.
    [0004] In order to obtain a greater weight gain compared with the first embodiment, the imaging apparatus 100 according to the second embodiment adopts the following arrangement. In order to contain and support the radiation detection panel 1, as in the first embodiment, a housing 7 has, on the upper surface of a bottom 7c, a flat bearing surface which contains and supports the panel 1 radiation detection. The bottom 7c has, in its lower surface, at least one concave portion intended to contain the control card 5 or the rechargeable battery 2. In the first embodiment, the bottom 7c is constituted by a monolayer structure. In contrast, in the second embodiment, the bottom 7c which supports the radiation detection panel 1 is constituted by a multilayer structure, as shown in FIGS. 4 and 5. The bottom 7c in the second embodiment has a structure in sandwich in which the surface layers 7c1 sandwich the two faces of a core layer 7c2. The surface layer 7c1 disposed on the side of the upper surface of the bottom 7c forms a flat surface. At least one concave portion is formed in the lower surface of the core layer 7c2. The concave portion may be made by a method of thinning the core layer 7c2. The surface layer 7c1 can be made from a highly rigid fiber-reinforced resin or fiber-reinforced metal, or a metal alloy such as an aluminum alloy or a magnesium alloy. The core layer 7c2 may consist of an expanded resin, or a structure of an aluminum alloy, resin, or the like having a honeycomb structure or a lattice structure. The core layer 7c2 has a very slight elasticity and a low density. It is therefore difficult to guarantee satisfactory rigidity using only the core layer 7c2. However, the total flexural stiffness is improved by sandwiching the core layer 7c2 between the strongly rigid surface layers 7c1. Since the core layer 7c2 is less rigid, the surface layer 7c1 on the lower surface side may also be formed to faithfully follow the concave portion, as shown in Figures 4 and 5, when forming the concave portion. This can limit a sudden change in bending stiffness of the sandwich structure. We will examine a case in which the flexural rigidity of the sandwich structure abruptly changes without employing the structure described above. In this case, a glass substrate constituting the bottom-supported sensor substrate 7c may be locally deformed by an external force near a portion at which stiffness suddenly changes, and stress concentration may occur. . Although the imaging apparatus 100 generally has satisfactory rigidity, the glass substrate may break. It has been chosen that the bending stiffness of the bottom 7c of the sandwich structure is greater than the bending rigidity of the top 7a serving as the radiation incident surface. This can relieve the load of a tensile stress caused by a bending stress imposed on the glass substrate, thereby easily obtaining a greater weight gain. In the second embodiment, as in the first embodiment, access covers 6 are arranged to cover the concave portions, providing electrical safety and replacing electrical components such as the control board and the rechargeable battery 2. To mitigate the influence of warping or the like caused by heat, the access cover 6 may be made of the same material as that of the surface layer 7c1 or the material of the multilayer structure. With this constitution, while ensuring the rigidity of the imaging apparatus 100, it is possible to arrange a structure intended to house the electrical components necessary for the imaging apparatus 100. It is possible to realize a greater reduction in weight, the thickness and size of the imaging apparatus 100, which is difficult in the prior art. [Third Embodiment] In the first and second embodiments, the top 7a of the housing 7 can be disassembled, as shown inter alia in FIG. 2. However, the disassembly structure of the housing 7 is not limited to this . The third embodiment employs a structure in which a housing 7 can easily mitigate the torsion of an imaging apparatus 100. To achieve weight gain while reducing torsion, the imaging apparatus 100 according to the third embodiment embodiment adopts the following arrangement. Figures 6A and 6B show the external appearance of the imaging apparatus 100 according to the third embodiment. Fig. 6A is a view showing the external appearance seen from the side through which radiation enters the imaging apparatus. Fig. 6B is a view showing the outward appearance seen from the opposite side to the incidence side of the radiation. Figures 7 and 8 are, respectively, a longitudinal sectional view taken along the line A - A of Figures 6A and 6B, and a cross-sectional view taken along the line B - B. In the third embodiment, one side 7b includes a pair of first sides 7b1 (for example, opposite each other) and a pair of second sides 7b2 (for example, opposite one another).
    [0005] As shown in FIG. 7, the housing 7 has a monocoque structure having a prismatic shape with a pair of opening portions, wherein a top 7a and a bottom 7c are connected by the pair of first sides 7101. The sides of the pair of second sides 7b2 are removably attached to the pair of opening parts of the monocoque structure, and can close the housing, thereby forming a closed space constituted by the interior of the housing 7. By dismounting the second sides 7b2 of the structure, the pair of opening parts on the side 7b of the housing 7 is opened. A radiation detection panel 1 can be introduced into the housing 7 via the opening parts. The monocoque structure formed from the top 7a, the bottom 7c and the first pair of sides 7b1 can be manufactured by autoclaving or the like using a fiber reinforced resin or the like. As in the first and second embodiments, the radiation detection panel 1 is supported by the flat upper surface of the bottom 7c, and at least one concave portion is formed on the bottom surface side of the bottom 7c. As shown in Figures 7 and 8, the bottom 7c according to the third embodiment can take a multilayer structure (sandwich structure), as in the second embodiment. Of course, the third embodiment may have, as an alternative, a monolayer background structure. As in the first case, a surface layer 7c1 may be made of a strongly rigid fiber-reinforced resin or a fiber-reinforced metal, or a metal alloy such as an aluminum alloy or a magnesium alloy. A core layer 7c2 may be an expanded resin, or a structure of an aluminum alloy, a resin, or the like having a honeycomb structure or a lattice structure. As in the second embodiment, it is found that the bending rigidity of the bottom 7c is greater than the bending stiffness of the top 7a. This can relieve the load of a tensile stress caused by a bending stress imposed on the glass substrate, thereby easily obtaining a greater weight gain.
    [0006] Concave parts formed in the casing 7 may be provided with electrical components such as a control card and a rechargeable battery 2. Access covers 6 are arranged in line with its concave parts so as to ensure the safety electrical and replacement of electrical components. With this constitution, the imaging apparatus 100 according to the third embodiment ensures the rigidity of the housing 7 as a whole. Thus, while obtaining the guarantee of rigidity, and a reduction in weight, thickness and size, it is possible to arrange a structure for storing the electrical components necessary for the imaging apparatus 100. reducing the weight, thickness and size of the imaging apparatus 100, which is difficult in the prior art. [X-ray System] Figure 9 shows an X-ray system including X-ray apparatus 100 described above. As shown in Fig. 9, X-rays (radiation) 211 generated by an X-ray tube (a radiation source) 210 pass through the chest 221 of a patient or subject 220 to be examined, and penetrate in the X-ray apparatus 100. Incident X-rays contain information about the inside of the patient's body 220. A scintillator emits light in correspondence with the X-ray input, and a sensor (a photoelectric converter) of a sensor panel converts the light photoelectrically, thereby obtaining electrical information. This electrical information is digitized, it undergoes image processing by an image processing unit (an image processor) 230, and can be observed on a display unit 240. The information having undergone the processing The image processor 230 can be transferred to a remote location by a transmission processing unit 250 such as a network (for example, the telephone, a local area network, or the Internet). The information that has been image processed by the image processor 230 may be displayed on a display unit 241 in a doctor's office or other such location, or may be saved on a display unit. recording as an optical disc. A doctor at the remote location can make a diagnosis. Information that has been image processed by the image processor 230 can also be recorded on a film 261 by a film processor 260. The X-ray apparatus according to the present invention can be applied to an X-ray machine medical, and an apparatus for analysis and examination using radiation, such as a non-destructive examination apparatus in a field other than medical. While the present invention has been described with reference to exemplary embodiments, it should be understood that it is not limited to them. The scope of the following claims shall be given the broadest interpretation so as to cover all such modifications and equivalent structures and functions.
