Interactive Segmentation and 3D Surface Reconstruction of Medical Images
Xujia Qin, Jianhua Hou · Journal of Engineering Graphics · 2001
This paper presents an interactive segmentation method of 3D medical images based on gray level information. Surface reconstruction of the segmented and extracted tissues or regions is created. The segmentation process is in four steps: filter the image,create the threshold values and binarize the image, process the image using proper mathematical morphology operation according to the feature of tissues or regions to extract, and fill the region to extract using seed fill algorithm. This is an interactive process. Isosurfaces of the extracted regions are created by MT algorithm. Normals of every triangular chip of the isosurface are calculated by using gray level gradient method. The surface of 3D reconstruction is displayed in high quality.
