1. A method for performing a procedure with an MRI system in which a series of images are acquired from a region of interest in a subject, the steps comprising:

  • a) placing an array of tracking coils on the subject;

    b) acquiring an NMR image using an NMR imaging pulse sequence prescribed by a set of scan parameters which image the region of interest;

    c) measuring the location of the tracking coils using an NMR position measurement pulse sequence;

    d) updating the scan parameters to track the movement of the subject using the measured tracking coil locations; and
