Abstract:
4D CT is a new emerging medical imaging technology commonly used for heart visualization and monitoring in cardiovascular medicine to detect abnormalities and specific type of illnesses. In order to enable more effective detection of particular heart conditions machine assisted applications can be of great benefit. One of the most important tasks in cardiovascular medical imaging is 3D segmentation that requires 3D ground truth of the heart model in order to optimize performance. 3D ground truth model is usually made by manual segmentation done by medical doctors. Specifically, the segmented 2D slices of the heart are manually segmented and the vertexes of the segmented borders are connected between neighboring slices. Using extracted geometry of the 3D point cloud corresponding to the segmented vertexes, in this paper, we aim to perform adequate rendering and mathematical modeling the 3D heart particle. For rendering and visualization we compute the normals depending on the vertex connectivity and geometric position, while mathematical modeling to be done is parametric providing thus possibility to flexibly deform the obtained model.
