Abstract

A method for fast off-resonance frequency deblurring of spiral MR images is presented. The method utilizes image-space deconvolution. The off-resonance phase is approximated as a separable quadratic function to allow rapid one-dimensional deconvolution with a small compromise in accuracy. The method is used to deblur an MR angiographic image to illustrate its effectiveness. (C) 2000 Wiley-Liss, Inc.
