Method of compensating for phase error of phase encoding gradient pulse in fast spin echo imaging method

Abstract

A method of compensating a phase error of a phase encoding gradient pulse in fast spin echo (FSE) imaging, wherein a bipolar type phase encoding gradient pulses for tuning are applied between a 90° RF signal and a first 180° RF signal in a FSE sequence to obtain a tuning value. Alternatively, an additional 180° RF signal is applied between a 90° RF signal and a first 180° RF signal in a FSE sequence, and then phase encoding gradient pulses for tuning are applied between the additional 180° RF signal and the first 180° RF signal to obtain a tuning value. The phase errors of the phase encoding gradient pulses are compensated for using the obtained tuning value. Accordingly, a ringing artifact or blurring phenomenon of an image can be reduced in the FSE imaging, and the contrast of an image can be improved.
