Abstract :
Specific absorption rate (SAR) and temperature increases produced inside a thorax model by a magnetic resonance imaging (MRI) apparatus have been studied both experimentally and numerically. The presence of a pacemaker into the thorax has been also considered, and its influence on the obtained SAR and temperature increases evaluated.
