Abstract
The goal of this study is to evaluate and compare motion tracking with two different modalities: NMR field probes and an optical MPT (Moiré Phase Tracking) camera system. This was done by simultaneously measuring the manually induced motion of a spherical phantom with both systems. Our experimental results indicate that the motion patterns measured with both methods are in good agreement. However, the accuracy of the motion estimates from the field probe measurements are of an order of magnitude worse than the camera's tracking results.
