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.
