Abstract

The present invention relates to a magnetic resonance scanning control method, which comprises: virtually amplifying the field angle of the readout direction to obtain the amplified readout direction data; dividing the readout direction data into a plurality of K-space data Perform phase alignment; according to a plurality of K-space data after phase alignment, respectively reconstruct a plurality of corresponding images; through the actual noise and preset noise, obtain the average number of acquisitions for noise reduction; the actual noise is obtained through the obtained after the above multiple image processing. The present invention also provides a storage medium and a magnetic resonance scanning control system. The magnetic resonance scanning control method, storage medium and system provided by the present invention can avoid multiple repeated scans in order to reduce noise, improve scanning efficiency, and The effect of controlling the scan time.

Description

technical field [0001] The present invention relates to the technical field of magnetic resonance scanning imaging, in particular to a magnetic resonance scanning control method, storage medium and system. Background technique [0002] Magnetic resonance refers to the phenomenon of spin magnetic resonance. Its meaning is wider, including nuclear magnetic resonance (nuclear magnetic resonance, NMR), electron paramagnetic resonance (electron paramagnetic resonance, EPR) or electron spin resonance (electron spin resonance, ESR). Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is a type of imaging equipment for medical examination made by using the phenomenon of nuclear magnetic resonance. Magnetic resonance imaging uses the principle of nuclear magnetic resonance. According to the different attenuation of the released energy in different structural environments inside the material, the position and type of the nucleus of the object can be known by detecting the em...
