Magnetic
Resonance imaging guided Focus Ultrasound Surgery (MRgFUS) is a highly
precise method for non-invasive tissue ablation. Existing MRgFUS systems are
mostly integrated into the patient table of the MR scanner. The objective of
this ongoing project is to establish an MRgFUS therapy unit combining a
commercial robotic assistance system with a fixed focus transducer as add-on.
The combined systems targeting precision was evaluated during focal spot
scanning procedures. The system proved to allow for accurate and highly
flexible focus positioning, and thus, might enable novel FUS treatment
access.
