Resource Description

This Matlab program (spiral_vdsn.m) generates a constant density spiral starting from the center of k-space out to a selected portion of k-space, and then switches over to a variable density spiral. In this scheme, only the outer regions of k-space are under-sampled. The program uses a Matlab GUI to generate a user-friendly interface. Inputs to the program include the image matrix size, the field of view, the variable density parameter (alpha) for the outer regions of k-space, and the transition point to switch over to the value of alpha for the outer region of k-space.
