The combination of ultrasound (US) and MR imaging results in a hybrid modality that offers a complementary description of the investigated anatomy [1] and increases control and assessment in image guided therapies. US imaging provides high temporal resolution and direct visualization of acoustic obstacles, while MRI offers excellent tissue contrast and a confirmed method for near real time thermometry. The value of combining these methods is more accurate targeting, efficient motion tracking and reliable, immediate assessment of the therapeutic results. The aim of this work is to set up an integrated environment for simultaneous acquisition of US and MR images with clinical standards, to evaluate the feasibility of this hybrid imaging and to assess the precision of image co-registration in the abdomen.
