REPETITIVE MOTION COMPENSATION TECHNIQUE FOR IMPROVING QUALITY OF 4D IMAGE

摘要

A method for acquiring a 4D image according to an embodiment of the present invention includes the steps of: reconstructing a 3D image composed of a plurality of frames from scan data which is gated; designating one or more target frames in the 3D image, acquiring motion information of neighboring frames in a predetermined time range for each target frame of the 3D image, and extending the predetermined time range; and acquiring the 4D image by compensating the motion for each of the target frames based on the acquired motion information. Accordingly, the present invention can improve the quality of the 4D image by using the motion information of the neighboring frames.;COPYRIGHT KIPO 2017
