In this study, predicting in vivo temperature increase by using a gel phantom experiment is presented. The theory behind this estimation comes from our earlier Gree?s function averaging technique, but fortunately by using this estimation method we do not need to do extensive computer simulations. The steady state temperature increase of in vivo can be predicted from phantom measurements therefore difficulty of making in-vivo experiments can be avoided; moreover this method can be used for setting safety limits in MRI by carefully considering the amount of prediction error that can exist due to mismatch of phantom properties.
