Abstract
An MRI system measures the movements of a subject during the acquisition of a series of NMR images and automatically updates the scan parameters such that the image plane or volume tracks the movement of the anatomy of interest. An array of tracking coils fasten to the subject and an NMR measurement pulse sequence is interleaved with the image acquisitions to measure the location of the tracking cols.
