It is an apparatus for generating a line image (medical image). As this X-ray image diagnostic apparatus, there are various types of X-ray image diagnostic apparatuses, and there are X-ray image diagnostic apparatuses using a flat panel detector (X-ray flat panel detector) for detecting X-rays.

  Among the flat panel detectors, a portable flat panel detector called a portable FPD (Flat Panel Detector) has been developed. When performing side imaging by irradiating the side surface of the subject on the top plate with X-rays, a portable flat detector is provided on the side surface of the subject. A photographing holding tool (holding mechanism), a grid holder for holding the grid, and the like are required.

  Normally, the side-viewing holding tool is fixed to the side of the top plate and holds a portable flat detector together with the grid holder. At this time, it takes time to mount and fix the flat detector and the grid to the tool. . Furthermore, due to the structure that the holding tool for side photographing is fixed to the side surface of the top plate, a portable flat detector can only be provided at a predetermined position, and a portable flat detector is installed. There are restrictions. Further, since there are many structures on the side surface of the top plate by the side photographing holding tool, and the side photographing holding tool has no use other than during side photographing, it interferes with various operations.

  That is, the flat detector 3c is configured by the flat detector main body 3c3 that detects X-rays and the support portion 12 that supports the flat detector main body 3c3. Thereby, the flat detector main body 3c3 is supported by the support part 12, and the flat detector 3c becomes independent. For this reason, for example, the flat detector 3c can be freely installed anywhere on the top plate 2a, so that the degree of freedom in arrangement can be improved. Furthermore, as compared with the case of using a side photographing holding tool, it is only necessary to unfold the support portion 12 of the flat detector 3c and place the flat detector 3c on the top plate 2a. Thus, installation workability can be improved. In addition, the side shooting holding tool is no longer required, and the side shooting holding tool can be removed, so that space saving can be realized compared to the case of using a side shooting holding tool with a complicated mechanism. it can.

  In the above-described fourth embodiment, the support portion 12 according to the first embodiment is attached to the flat detector main body 3c3. However, the present invention is not limited to this, for example, the second or third embodiment. You may make it attach the support part 12 (refer FIG.6 and FIG.7) which concerns on a form to the flat detector main body 3c3. In this case, it is possible to obtain the same effect as in the second or third embodiment.

  In the first to fourth embodiments described above, the holding unit 11 incorporating the flat detector 3c is supported by the support unit 12 so as to be substantially perpendicular to the mounting surface which is the upper surface of the top plate 2a. However, the present invention is not limited to this, and for example, it may be supported by the support portion 12 while being inclined with respect to the placement surface which is the upper surface of the top plate 2a. The inclination angle at this time varies depending on the imaging region (for example, arms and feet) and the content of imaging.

  In the above-described first to fourth embodiments, the example in which the flat detector 3c is placed on the top plate 2a has been described. However, the present invention is not limited to this, and flat detection is performed at a place other than the top plate 2a. A vessel 3c may be placed.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
