Abstract

A suitable database, including a temporal series of images is acquired (3) and subjected to a suitable binary segmentation (4) to create temporally sequenced binary coded images large portions corresponding to blood are labeled as unity, the rest is set to zero. A preceding binary coded image (8a) corresponding to a phase (t) from the temporal sequence is subtracted from a subsequent binary coded image (8b) corresponding to a phase (t+1) yielding a multi-dimensional temporal feature map (8c). A pre-defined deformable shape model is deformed (14) to fit the temporal feature map. The segmentation results are displayed (18) using suitable display (47). The segmented surface is overlaid on the original data using a two-, three- or four-dimensional visualization technique and can be presented as a color-code in a suitable transparency mode.
