Abstract

High Intensity Focussed Ultrasound (HIFU) is a therapy that enables to perform cancer surgery by localised heating of the tumour. The tumour tissues are burnt by focussed ultrasound waves. A transducer emits these ultrasound waves. On the other hand Magnetic Resonance Imaging (MRI) is a diagnostic tool to visualise cancer tu- mours. MRI employs large magnets for creating a homogeneous magnetic field and gradients coils for creating magnetic field gradients. These adjustments of the fields enable to select which tissue slices will be imaged.
