Description

technical field [0001] The present application relates to the technical field of magnetic resonance image processing, in particular to an accelerated magnetic resonance super-resolution imaging method, device, equipment and medium. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is an imaging technique that uses the signal generated by the resonance of the atomic nucleus in a strong magnetic field to reconstruct the image. It is a nuclear physics phenomenon. The principle of magnetic resonance imaging is to use radio frequency pulses to excite atomic nuclei with non-zero spins in a magnetic field. When the radio frequency pulses stop, the atomic nuclei relax. During the relaxation process, the induction coil is used to collect signals, and press A certain mathematical method is used to reconstruct and form a mathematical image. [0003] Magnetic resonance imaging technology is different from other imaging technologies. The amount o...
