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.

Abstract
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.| File | Dimensione | Formato | |
