| Abstract: | Image segmentation is a key step for image processing. to extract the outline of the heart for 3D-modeling which This study developed an improved region growing algorithm based on the acquisition of canine cardiac CT images from animal experiment. In this paper the method was also compared with the classic algorithm of threshold segmentation The result showed that the method can be used for the 3D display technology of cardiac electrical activity in clinica electrophysiology mapping. |
