To ensure safe use of MRI it is desirable to estimate and limit the Specific energy Absorption Rate (SAR) averaged over the whole body, whole head, and the maximum SAR averaged over any 1 or 10g region in the body. Safety guidelines by the IEC recommend limits on the maximum values of both SAR and temperature. In this work, we present a useful open source software which includes tools to locally average SAR and to compute temperature increase with different methods, letting the user choose whether to prioritize accuracy or computation speed.
