Abstract

The invention relates to a magnetic resonance imaging method and device, a storage medium and computer equipment. On one hand, after K space data is obtained through undersampling, image reconstruction is not directly carried out; instead, data recovery is firstly carried out on undersampling data to obtain corresponding full sampling data, and then a corresponding magnetic resonance image is obtained based on the full sampling data; on the other hand, when data recovery is carried out, the operation is based on reconstruction data of a bare data domain; compared with data of an image domain,loss of amplitude and phase information can be avoided, and compared with data of a K space, more dominant features can be extracted, so that feature information contained in a magnetic resonance image is richer, and the image quality of the magnetic resonance image is improved.

Description

technical field [0001] The present application relates to the field of magnetic resonance technology, in particular to a magnetic resonance imaging method, device, storage medium and computer equipment. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) performs imaging according to the characteristics of the magnetic nucleus in the living body to generate resonance signals in the static magnetic field. It has high image resolution, multiple imaging parameters, slices in any direction, and no ionizing radiation damage to the human body. With significant advantages, it has become one of the most advanced medical imaging methods and has been more and more widely used in clinical and scientific research. [0003] Conventional magnetic resonance imaging takes a long time, which leads to high cost. At the same time, the body movement of the subject will cause image blur and motion artifacts. In order to shorten the scanning imaging time, un...
