There is provided an X-ray CT apparatus including: an X-ray source; a wedge which is disposed between the X-ray source and a subject and in which a shield blocking apart of an X ray is formed; a wedge driving unit for moving position of the wedge; and a system control unit controlling the wedge driving unit during a scan execution period to control the position of the wedge.

A couch device including sliders axially supported by lower ends of both of link members, and including nut members. Guide rails substantially horizontally guide each slider. A screw member is arranged along the guide rail and is configured to apply a driving force to each slider when it is relatively rotated for each nut member and, due to the driving force, substantially horizontally transfer each slider. A clutch unit selectively carries out the operations of rotating one nut member integrated with the screw member such that the driving force is prevented from being applied to one slider, or relatively rotating one nut member for the screw member such that the driving force is applied to one slider. A binding unit binds one slider to the guide rail when the driving force is not applied to the one slider.

Couch device and functional image/morphological image diagnosis apparatus

An X-ray CT radiation detector includes a heat insulating case mounted on a rotating base, a radiation incident window formed in the heat insulating case, a detection panel on which detection elements for detecting radiation incident through the radiation incident window are arrayed. The detection panel is positioned to form a fluid circulatory path in the heat insulating case. A circulator for circulating the fluid is placed in the circulatory path. The circulatory path and circulation of the fluid by the circulator make it possible to make the temperature of the detection panel relatively uniform.
