Abstract

This work introduces a rapid UTE-based SAR estimation method that eliminates explicit ∣B1+∣ mapping, demonstrating strong potential for efficient subject-specific RF safety monitoring from a single short acquisition and paving the way toward clinically practical, image-based SAR assessment at 3T.
