The image segmentation plays an important role in medical image processing. Many segmentation algorithms exist. Most of them produce raster data which is not suitable for 3D geometrical modeling of human tissues. In this paper, a vector segmentation algorithm based on a 3D Delaunay triangulation is proposed. Tetrahedral mesh is used to divide a volumetric(More)
The article focuses on modification of traditional Marching cubes algorithm for medical applications. Main disadvantage of the traditional algorithm is size of models. A reduction process has been added to the MC to produce much smaller models. The reduction process is applied during the MC, after processing of each input data layer. Resulting models are(More)
This paper deals with the new concept of network based virtual collaborative environment to support clinical applications of 3D models of human tissues, created from CT/MR data. It is a topic lying between 3D tissue modeling and PACS systems. Designed system allows clinical realizations of 3D applications as a service to clinical workplaces, provided by(More)
