Abstract
An X-ray CT system includes a fixed frame portion and a rotating frame portion. Being provided with X-ray tubes, the rotating frame portion is arranged so as to rotate with respect to the fixed frame portion. Vane members for feeding air are secured on the rotating frame portion. In operation, with the rotation of the vane members together with the rotating frame portion, cool air is introduced into the rotating frame portion. Consequently, heated instruments, such as the X-ray tubes, in the rotating frame can be cooled down effectively.
