Benefits of technology

The technical solution described in this patented technology allows for precise adjustment of the intensity (RF) pulses used during MRI scans without being influenced by external influences like temperature or pressure variations. This results in improved image quality while maintaining consistently high-quality images captured under varying conditions over time.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving image quality when an MRI scanner operates with different types of objects like humans' bodies during MR angiography procedures. These variations can cause issues for accurate results because they result in changes made on the signal intensity at specific locations within the subject being imaged. Prior methods have resulted in suboptimal solutions which require iterative calculations over many samples before obtaining the best estimate.

Abstract

The invention provides a control method and a control device of a magnetic resonance system. The control method comprises the following steps: measuring and recording radio frequency field data; obtaining an amplitude estimation value of the radio frequency field based on the radio frequency field data and a particle swarm algorithm; setting an amplitude control parameter of the radio frequency pulse based on the amplitude estimation value; acquiring a setting instruction of the sequence mode of the radio frequency pulse; and outputting a control signal based on the amplitude control parameter and the setting instruction. According to the configuration, on one hand, actual data of the radio frequency field can be found through measurement, on the other hand, the amplitude estimation value of the radio frequency field can be obtained based on the particle swarm optimization, the influence of noise errors is reduced, and the radio frequency amplitude calibration precision and speed are improved. Therefore, the problem that in the prior art, due to the fact that the field intensity of the radio frequency field is affected by various factors, the expected field intensity is changed, and the imaging effect is affected is solved.
