ABSTRACT:
A calibration procedure is performed prior to an off-axis MR scan to measure the MRI system timing error in applying a frequency modulation waveform to the system receiver. Phase errors which otherwise occur when performing non-Cartesian scans are either prospectively reduced by offsetting the timing error or retrospectively offset by applying phase corrections to the acquired image data.
