BACKGROUND/PURPOSE The VPAC1 receptor, a member of the vasoactive intestinal peptide receptors (VIPRs), is overexpressed in the most frequently occurring malignant tumors and plays a major role in the progression and angiogenesis of a number of malignancies. Recently, phage display has become widely used for many applications, including ligand generation(More)
We propose a method of reliable tracking orientation and flexible step size fiber tracking. A new directional strategy was defined to select one optimal tracking orientation from each directional set, which was based on the single-tensor model and the two-tensor model. The directional set of planar voxels contained three tracking directions: two from the(More)
MR diffusion tensor imaging fiber tracking (DTI-FT) could lead to false propagation because of image noise and low resolution of DTI. A variety of fiber clustering (FC) approaches have been used to refine the tract configuration. The measure of fiber similarity metric is vital in the FC algorithms. In this paper, two most common used fiber similarity(More)
