The invention relates to a motion monitoring method applied to magnetic resonance imaging, a magnetic resonance imaging system, an electronic device and a storage medium. The motion monitoring method applied to magnetic resonance imaging comprises the steps that real-time magnetic field information of a scanned part of a subject is detected through a plurality of diamond NV color center sensors, wherein the plurality of diamond NV color center sensors are arranged at different positions of the scanned part of the subject; and according to the variable quantity of the real-time magnetic field information detected by the diamond NV color center sensors and the magnetic field distribution information of the magnetic resonance imaging system, the spatial motion information of the scanned part of the subject is determined. Through the motion detection method and device, the problem that motion artifacts exist in a magnetic resonance image due to the fact that motion detection cannot be carried out on a subject in real time in the prior art is solved, and the technical effect that motion detection can be carried out on the subject in real time is achieved.
Description
technical field [0001] The present application relates to the technical field of magnetic resonance imaging, in particular to a motion monitoring method applied to magnetic resonance imaging, a magnetic resonance imaging system, an electronic device and a storage medium. Background technique [0002] Magnetic Resonance Imaging (MRI for short) is an imaging technique that uses the signal generated by the resonance of atomic nuclei in a strong magnetic field to reconstruct an image, and is a nuclear physics phenomenon. It uses radio frequency pulses to excite atomic nuclei with non-zero spins in a magnetic field. After the radio frequency pulses stop, the atomic nuclei relax. During the relaxation process, the signals are collected by induction coils and reconstructed according to certain mathematical methods. Mathematical image. [0003] MRI imaging is different from other imaging techniques in that it provides far more information than many other imaging techniques in medic...
