Utility
High intensity focused ultrasound transducer optimization
31 Oct 23
When planning magnetic resonance (MR) guided high intensity focused ultrasonic (HIFU) therapy, HIFU transducer element parameters are optimized as a function of 3D MR data describing a size, shape, and position of a region of interest (ROI) (146) and any obstructions (144) between the HIFU transducer elements and the ROI (146).
