The Influence of Averaging Schemes and Exposure Duration on the Correlation Between Temperature Elevation and RF Power Absorption Metrics in MRI Scans [Health Matters]

In this article, we examine the correlation between temperature increments induced in the human body by RF exposure from magnetic resonance imaging (MRI) scanners and the corresponding power absorption. In particular, we consider the influences of absorption metrics-namely, the specific absorption rate (SAR) or volumetric absorption rate (VAR), averaging scheme, and exposure time-on the correlation.
