Magnetic Resonance Guided High Intensity Focused Ultrasound (MRgHIFU) for Pain Palliation of Bone Metastases

MRgHIFU treatment will be delivered using a Philips Sonalleve system, which integrates a high intensity phased array focused ultrasound transducer with our Philips 3T Achieva imaging system. An electromechanical transducer positioning system is used to deliver spatially and temporally controlled ultrasound energy and thermal heat to tissues non-invasively. The MR system is used to provide images to plan the therapy, and to guide and monitor the thermal ablation with thermal imaging during the treatment.
