Description
technical field [0001] The present invention relates to the technical field of magnetic resonance imaging, in particular to an artifact elimination method, system, terminal and storage medium. Background technique [0002] With the development of medical technology, Magnetic Resonance Imaging (MRI) technology is becoming more and more important. Magnetic resonance imaging is a routine procedure for diagnosing and treating various diseases and injuries. It can accurately reflect the pathological tissue conditions, enable doctors to make accurate diagnoses, and provide targeted treatment to patients based on the results of magnetic resonance imaging. [0003] At present, imaging signals obtained by magnetic resonance imaging are affected by electromagnetic interference (Electromagnetic Interference, EMI) and noise, which will cause magnetic resonance imaging artifacts, thereby reducing the accuracy of magnetic resonance imaging.
