Abstract

For estimating SAR in MR scanning, a value for a SAR metric is determined from patient measurements, such as a depth camera image of the outer surface of a patient. A machine-learned model is used in the determination, such as for segmenting different tissue types with different electric field characteristics and/or estimating a SAR characteristic from tissue maps. Rather than time consuming calculations to model the patient and/or estimate SAR from patient information, the machine-learned model is used to estimate patient-specific SAR from the measurements of the patient more rapidly and accurately.
