AI Technical Summary
In existing technologies, the problem of radio frequency energy deposition in human tissues by ultra-high field magnetic resonance imaging systems is difficult to measure in real time and accurately, resulting in uneven imaging quality and insufficient safety.
By acquiring the mapping relationship between the radio frequency coil transmission field and electric field distribution data of each channel of the radio frequency transmission coil, the pre-trained radio frequency electric field prediction model is used to determine the radio frequency electric field distribution data of the subject relative to each channel in real time, and the weighting weights are adjusted to calculate the SAR value distribution.
It enables real-time and accurate measurement of SAR value distribution, improving the imaging quality of magnetic resonance imaging and ensuring the safety of subjects.
