Surgical Guidance with Compounded Ultrasound Imaging

Abstract: in one approach for surgical guidance with compounded ultrasound imaging, a neural field uses both probe tracking and ultrasound imaging to compound the ultrasound data into three-dimensions with alignment of the component fields of view. accurate compounding is provided, and the compounding may operate in real-time. in another approach for visualization with pre-operative data, modeling (e.g., the neural field) from ultrasound is used to generate a 3d deformation field, which is then applied to the pre-operative data. the 3d deformation field may be applied in rendering rather than to the pre-operative volume dataset. this 3d deformation may be used in real-time, allowing for synchronized 3d ultrasound and 3d pre-operative imaging.
