Retrospective cardiac gating with cine scans on a multislice scanner

摘要

A method for obtaining a set of still image slices of a moving heart of a patient (22) utilizes a multi-slice CT scanner (10) and an EKG data recorder (52). The method includes steps of simultaneously recording EKG data (60) of the patient's cardiac utilizing the EKG data recorder while cine scanning and recording plural CT image slices (62, 66, 70) of the patient's heart utilizing the multi-slice CT scanner; correlating the recorded cine scanned CT image slices with the recorded EKG data; and selecting segmented images (64, 68, 72) of the set of recorded image slices corresponding to a selected portion of the patient's cardiac cycle as indicated by the correlated, recorded EKG data, the selected segmented images thereby becoming the set of still image slices. <IMAGE> <IMAGE>
