Intersubject specific absorption rate variability analysis through construction of 23 realistic body models for prostate imaging at 7T

Purpose For ultrahigh field (UHF) MRI, the expected local specific absorption rate (SAR) distribution is usually calculated by numerical simulations using a limited number of generic body models and adding a safety margin to take into account intersubject variability. Assessment of this variability...
