In a patient exam typically a series of pulse sequences with very different power levels and SAR levels are applied. Temperature increase caused by SAR absorption may damage tissues, and development of fast temperature computation methods could be useful. We propose a rapid method to predict temperature increase over an entire patient exam with time-varying SAR levels applied, after characterizing the temperature tissue response to a short SAR pulse.
