Method for rapid spin echo MRT imaging

摘要

The method involves forming a base by a series of excitation and radio frequency refocusing pulses of two echo groups according to a spin echo principle, where one echo group is utilized to receive a reference data set or a training data set, which is utilized for self calibration and another echo group is recorded by down sampling. The echo groups are independently phase-encoded by implementing independent gradients along a phase coding direction. The echo groups are independently reconstructed.
