PROBLEM TO BE SOLVED: To provide a drive unit used for accurately imaging a movable site such as a joint. SOLUTION: This drive unit is characterized in having a fixing means fixing a subject, a loading device having a loading means applying a predetermined load to the subject via a load cell, and a moving means moving the load drive unit along an arc-shaped rail provided outside a rotation center of the fixing means. When capturing a CT image, a fluoroscopic image, and an MRI image while continuously moving the joint and the vertebra of the subject, this drive unit applies the load to the joint and vertebra, continuously moves the joint and the vertebra by a rotary movement (revolving motion) fixedly retaining the rotation center of the joint and the vertebra, and smoothly and accurately images kymography of the joint and the like.
