1. A diagnostic imaging apparatus comprising: a memory, which stores a plurality of 3D images, each 3D image depicting a common anatomical region of interest of a subject with portions of the subject anatomy differently positioned in each of the 3D images, a first of the 3D images having reference points which define a designated anatomical component; one or more processors programmed to: calculate a propagation of the reference points from the first 3D image into other 3D images; define transforms which describe the propagation of the reference points between 3D images; apply inverses of the transforms to the 3D images to define a series of frames; and display viewing planes of the 3D images in a cine format, in which frames the anatomical component defined by the reference points in each of the 3D images remains fixed while the other portions of the anatomical region of interest move relative to the fixed designated anatomical component.
