N2 - Magnetic resonance imaging (MRI) allows continuous temperature mapping inside the human body and is thus a promising tool to guide thermal therapies. For abdominal organs, a real time motion compensation is required to allow quantitative temperature measurements and to permit retro-active control of the heating device. Although optical flow based algorithms have shown promise for this role, intensity variations induced by the heating process may lead to misregistration.
