置決め装置。 In a CT apparatus that performs scan measurement by making the height hc from a predetermined reference position to the center of the imaged part of a subject lying on a bed coincide with the height H from the reference position to the center of the scan measurement area, A subject height detection circuit for detecting the height L of the imaging portion of the subject; a bed height detection circuit for detecting the height hT of the bed from the reference position; and detection by both of these detection circuits. The height hc (=hT+L2) is determined from the height L and hT, and a signal corresponding to the difference (=H-hc) between this height hc and the height H is given to the vertical movement device of the bed. and a determination circuit for making the height H match the height hc.
