Title:
MAGNETIC RESONANCE IMAGING METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/019412
Kind Code:
A1
Abstract:
A magnetic resonance imaging method and apparatus, and a device and a storage medium. The magnetic resonance imaging method comprises: acquiring a three-dimensional point spread function of a target object (1010); acquiring a sensitivity map of the target object (1020); adjusting an encoding strategy of a balanced steady-state free precession pulse sequence by means of wave gradient pulse controlled aliasing in parallel imaging, wherein the encoding strategy comprises an encoding strategy of a phase direction and an encoding strategy of a layer selection direction (1030); based on the balanced steady-state free precession pulse sequence having the encoding strategy adjusted, acquiring three-dimensional under-sampled data of the target object, wherein fields of view of imaging of the three-dimensional under-sampled data and the sensitivity map are the same (1040); and performing image reconstruction on the three-dimensional under-sampled data according to the three-dimensional point spread function and the sensitivity map, so as to generate a magnetic resonance image of the target object (1050).
