✦ Synopsis

Abstract

Diffusion‐weighted MRI is a clinically useful technique, but its utility is compromised by high sensitivity to patient motion. Use of radial‐scan data acquisition and projection reconstruction, rather than the conventional Fourier imaging method, can substantially reduce the sensitivity to global translational motion of the object. The basis of this concept and a demonstration of the technique in an animal imaging experiment are presented.

## Abstract A simple technique is proposed in which a phantom could be used to calibrate an image acquired during an magnetic resonance imaging scan. The method corrects for the effects of nonlinearities in the gradient fields, and in principle does so exactly. The mathematics behind the technique
