Abstract
A gantry and a subject holder on which a subject can be fixed in his sitting position are supported on a main frame. A gantry drive unit moves the gantry to a position of examination and also drives it until an inclination angle for examination is reached. A computing unit performs mathematical operations based on the data representing the inclination angle of the gantry and produces a control signal for controlling a holder moving direction which is determined in accordance with the inclination angle. A moving unit moves the holder and a subject fixed thereon in the holder moving direction in response to the control signal.
