Improvement of diffusion weighted images with reduced-view radial acquisition

Abstract

Diffusion imaging techniques using radial trajectories have been presented including the radial turbo-spin-echo (rTSE) and highly constrained backprojection (HYPR) sequences, which reduce not only the imaging time but also image distortions (1, 2). Here, we propose a method to further improve the image quality by estimating the missing information from the projection data acquired with a reduced number of projection views.
