A fast method is proposed for DTI neural tract extraction and visualization. Existing efficient tract extraction approaches are based on localizing fibers from a pre-computed whole brain tractography. However, the tracking parameters of precomputed fibers cannot be easily adjusted quickly. Moreover, high noise in the estimated orientation around crossing and neighboring tracts often diverts fibers...
This paper describes a novel automatic 3D surface extraction method for biomedical volume images. In this technique, the region of interesting (ROI) in 2D slice images is selected interactively, 3D ROI edge surface is determined by using Laplace operator based tracking method. According to coplanar principle of the voxel, the edge surface in ROI is then automatically extracted by region growing approach...
