SAR and B1+rms calculator update

April 10, 2018

The SAR and B1+rms calculator has been updated to version 2.2. This uses a more realistic model (assumes the body within the RF coil is a uniform cylinder, rather than a sphere). It also calculates the average (whole body) SAR whereas before it calculated the peak SAR- so it doesn’t so easily jump out of the Normal … More SAR and B1+rms calculator update
