Abstract
A CT image processing devicewhich processes projection data in synchronization with a periodic motion of a portion of a subject includes an ROI calculation unitwhich calculates specific information on an ROI for synchronization for each scanning angle so as to track the target portion of the subject. As a result, a strong synchronization signal is obtained, a characteristic amount in which breathing beat and heartbeat sufficiently appear can be measured, and simple synchronization processing is made possible by using the projection data. A dedicated device for obtaining the heartbeat or breathing beat such as ECG and a respiratory measuring device is not required, and a heartbeat signal and a breathing beat signal can be obtained from an ROI signal of the projection data. As a result, blurring on an image caused by the heartbeat can be eliminated, and an image quality is extremely improved.
