MRI Guided Focused Ultrasound Surgery for Cancer Treatments

Focused ultrasound can be used for noninvasive thermal coagulation of tumors. However, the previous studies have shown that there is significant variability in the coagulated tissue volumes when the system is used in an open-loop manner. Therefore it has been difficult to predict the actual temperature elevation and thus, the thermal exposure during the treatments. Magnetic Resonance Imaging (MRI) guided ultrasound surgery systems have been developed in order to minimize this variability and to assure complete tissue coagulation in the target volume. Experiments and early clinical trials have shown that the MRI thermometry can provide adequate feedback to assure correct target location and to assure adequate thermal exposure. This system is currently undergoing clinical testing in three institutions for noninvasive breast cancer treatments.
