Abstract

The disclosure discloses a particle accelerator-based nuclear magnetic resonance magnetic field measurement method and system, including: using the particle accelerator to emit accelerated particles to the area to be measured of the nuclear magnetic resonance instrument; recording the trajectory and trajectory changes of the accelerated particles in the area to be measured point; change the emission angle of the particle accelerator, and emit accelerated particles to the area to be measured of the nuclear magnetic resonance instrument again; record the trajectory of the accelerated particles in the area to be measured after changing the emission angle and the trajectory change point; repeat the previous step to set the number of times; Then, for each trajectory, use the magnetic deflection method to calculate the magnetic field strength of the current trajectory; for each trajectory change point, use the hydrogen nuclear spin method to calculate the magnetic field strength of the current trajectory change point; based on the magnetic field strength of all trajectory and the magnetic field strength of all track points, draw the magnetic field strength boundary line, and obtain the magnetic field strength of the area to be measured of the nuclear magnetic resonance instrument.

Description

technical field [0001] The present disclosure relates to the technical field of medical equipment, in particular to a particle accelerator-based nuclear magnetic resonance magnetic field measurement method and system. Background technique [0002] The statements in this section merely mention background art related to the present disclosure and do not necessarily constitute prior art. [0003] With the continuous development of the times, in the face of the increasing number of tumor diseases, medical technology is also constantly improving. Through an electronic slip ring, the radiotherapy instrument and the nuclear magnetic resonance instrument are combined, and the obtained magnetic resonance accelerator can realize the effect of radiotherapy while positioning. But because the nuclear magnetic resonance instrument is inside the electronic slip ring, and when it works, it will generate a magnetic field to excite the hydrogen nuclei in the human body in the magnetic field,...
