Conditional safety margins for less conservative peak local SAR assessment: A probabilistic approach

PURPOSE: The introduction of a linear safety factor to address peak local specific absorption rate (pSAR(10g)) uncertainties (eg, intersubject variation, modeling inaccuracies) bears one considerable drawback: It often results in over‐conservative scanning constraints. We present a more efficient ap...
