The methodology used for this HIFU device capitalizes on the thermal properties of volumetric ablation rather than point ablation used by other focused ultrasound systems. Thus it is anticipated that this device will have a shorter treatment time compared to other HIFU machines. This HIFU system, via real-time MR thermometry monitoring, has automated thermal feedback during the procedure which may enhance safety. This pilot study will not only assess the safety of this device but will enable us to delineate the treatment capabilities of this system for future use in patients who want uterine sparing non-surgical treatment for symptomatic fibroids.
