Title:
RADIO FREQUENCY ENERGY DEPOSITION PREDICTION METHOD AND APPARATUS, RADIO FREQUENCY ENERGY DEPOSITION MONITORING METHOD AND APPARATUS, AND DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/188237
Kind Code:
A1
Abstract:
A radio frequency energy deposition prediction method and apparatus, a radio frequency energy deposition monitoring method and apparatus, and a device and a medium. The prediction method comprises: collecting a magnetic resonance scanning structural image of a scanning object, and performing tissue segmentation on the basis of the magnetic resonance scanning structural image to establish a three-dimensional biological model of the scanning object (S110); establishing a biological electromagnetic simulation model according to the three-dimensional biological model (S120); and establishing a multi-channel radio frequency coil model according to a preset scanning strategy, and simulating and determining a radio frequency energy deposition value by combining the biological electromagnetic simulation model and the multi-channel radio frequency coil model (S130). The monitoring method comprises: predicting a radio frequency energy deposition value according to the prediction method, and adjusting a scanning strategy according to a prediction result.
