Abstract
A method and system for estimating a specific absorption rate of a tissue region prior to performing a magnetic resonance (MR) imaging scan on the tissue region. The method comprises radiating the tissue region with a plurality of short pulses, wherein the tissue region emits thermoacoustic signals responsive to the short pulses, receiving the thermoacoustic signals by at least one ultrasonic transducer, calculating a temperature rise of the tissue region based on the received thermoacoustic signals, scaling the temperature rise to estimate a temperature rise of the tissue region resulting from an MR imaging scan, and estimating the specific absorption rate of the tissue region based on the estimated temperature rise.
