Abstract

A system includes a storage device storing a set of instructions and a processor in communication with the storage device. When executing the instructions, the processor is configured to cause the system to obtain one or more scanning parameters. The processor is also configured to cause the system to determine a first flip angle of a first fat suppression RF pulse and a second flip angle of a second fat suppression RF pulse. The processor is further configured to cause the system to scan a subject by applying an RF pulse sequence including the first fat suppression RF pulse, the second fat suppression RF pulse, and an excitation RF pulse. The processor is also configured to cause the system to receive magnetic resonance signals based on the scanning of the subject and reconstructing an image of the subject based on the MR signals.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a magnetic resonance fat suppression image acquisition method, a storage medium and a scanning system. Background technique [0002] In the traditional frequency-selective fat suppression method, a radio frequency soft pulse with an appropriate bandwidth is applied before slice-selective excitation imaging to excite the fat signal and gradient dephase, so that the water signal is preserved and the fat signal is suppressed. The uniformity of fat pressing is greatly affected by the inhomogeneity of the radio frequency emission field (ie, B1), that is, the uniformity of fat pressing by traditional methods is very sensitive to B1. In T2FSE (fast spin echo, fast spin echo) imaging, the influence of B1 inhomogeneity on the uniformity of fat suppression is often more significant. The B1 unevenness of the 3T system is obvious, and the uniformity of fat pressing has become a serious prob...
