Abstract

The invention relates to a magnetic resonance spectrum imaging method and device, computer equipment and a storage medium. The method comprises the steps of scanning for multiple times by adopting a preset scanning sequence, wherein the preset scanning sequence comprises an excitation pulse and a spatial positioning coding gradient, the excitation pulse comprises three mutually perpendicular layer selection pulses, and the three mutually perpendicular layer selection pulses are matched with the corresponding spatial positioning gradients to determine voxels of interest; acquiring a response signal of each scanning, and setting the acquisition times of each filling position in the K space according to a preset weight; filling the response signals acquired for multiple times into corresponding positions of the K space to generate K space data; and generating a magnetic resonance image according to the K space data, and separating a spectrum image of the voxel of interest according to the magnetic resonance image. By adopting the method, the spectrum image of the voxel of interest can be accurately separated.

Description

technical field [0001] The present application relates to the field of magnetic resonance technology, and in particular, to a magnetic resonance spectroscopy imaging method, device, computer equipment and storage medium. Background technique [0002] Magnetic Resonance Imaging (MRI) is an imaging technique that uses the signals generated by the resonance of atomic nuclei in a strong magnetic field to reconstruct images. [0003] In the related art, the magnetic resonance equipment first uses radio frequency pulses to excite the region of interest in the magnetic field, and then acquires signals during the relaxation process of the region of interest, thereby forming an image of the region of interest; [0004] However, if the magnetic field of the system formed by the magnetic resonance equipment is not uniform, the adjacent regions of the region of interest will also be excited, resulting in interference signals, which in turn lead to deviations in the image of the region o...
