In the present invention, only one of the top plate portion of the mounting table and the imaging portion may be provided so as to be movable.

Further, in the above-described first and second embodiments, the example in which the head support member is detachably provided on the top plate portion of the mounting table has been shown, but the present invention is not limited to this. In the present invention, the head support member does not necessarily have to be detachably provided on the top plate of the mounting table. For example, the head support member may be non-detachably fixed to the top plate of the mounting table.

Further, in the above-described first and second embodiments, an example in which the body portion of the head support member is provided in a substantially semi-cylindrical shape has been shown, but the present invention is not limited to this. In the present invention, the body portion of the head support member may be provided in a substantially half-square tube shape (such as a U-shape) or may be provided in a flat shape (flat plate shape). When the body portion of the head support member is provided in a substantially semi-cylindrical shape, the substantially semi-cylindrical shape may be a half of a perfect circle or a half of an ellipse.

Further, in the first and second embodiments, the marking portion of the head support member is configured to indicate only the imaging end of the imaging range of the imaging portion by the first marking portion and the second marking portion. Although an example is shown, the present invention is not limited to this. In the present invention, the marking portion of the head support member may be configured to indicate the entire imaging range of the imaging section. For example, the marking portion of the head support member may be configured to indicate the entire imaging range of the imaging unit by making the color different from that of the other portions.

Further, in the first and second embodiments described above, an example is shown in which the marking portion of the head support portion is configured to indicate only a single imaging range, but the present invention is not limited to this. In the present invention, when the diagnostic imaging apparatus has a plurality of imaging ranges, the marking portion of the head support may be configured to indicate each of the plurality of imaging ranges. For example, by providing a plurality of first marking portions, each marking portion may be configured to indicate each of a plurality of imaging ranges.

Further, in the above-described first and second embodiments, an example in which the regulating member is made of the same material as the head support member is shown, but the present invention is not limited to this. In the present invention, the restricting member may be made of a material different from that of the head support member. For example, the head support member may be made of a resin material, while the regulating member may be made of a metal material.

Further, in the above-described first and second embodiments, an example in which the diagnostic imaging apparatus is configured to include the regulating member has been described, but the present invention is not limited to this. In the present invention, the diagnostic imaging apparatus does not necessarily have to be configured to include the restricting member.

Further, in the above-described first and second embodiments, the restricting member is detachably attached to the head supporting member, but the present invention is not limited to this. In the present invention, the restricting member does not necessarily have to be detachably attached to the head support member. For example, the restricting member may be non-detachably fixed to the head support member.

Further, in the first and second embodiments, the diagnostic imaging apparatus is configured to include a regulating member (first regulating member) for regulating the position of the top of the subject's head at the position of the first mark. However, the present invention is not limited to this. In the present invention, the diagnostic imaging apparatus may include a regulating member (second regulating member) for regulating the position of the portion opposite to the parietal region of the subject at the position of the second marking portion. In this case, the diagnostic imaging apparatus may include both the first regulating member and the second regulating member, or may include only one of them.

Further, in the above-described first and second embodiments, an example in which the second marking portion of the head support member is configured by the end portion of the head support member is shown, but the present invention is not limited to this. . In the present invention, the second marking portion of the head support member is composed of a figure attached to the head support member, a recess provided on the head support member, or a protrusion provided on the head support member. may have been

Further, in the above-described first embodiment, the example in which the first marking portion of the head support member is attached to the outer surface of the main body portion of the head support member has been described, but the present invention is not limited to this. . In the present invention, the first marking portion of the head support member may be attached to the inner surface (support surface) of the body portion of the head support member.

Further, in the above-described second embodiment, the example in which the first marking portion of the head support member is configured by the concave portion provided in the head support member has been described, but the present invention is not limited to this. In the present invention, the first marking portion of the head support member may be configured by a convex portion provided on the head support member.
