摘要
A clinical and training apparatus that collects and processes physical space data while performing an image-guided procedure on an anatomical area of interest includes a calibration probe, a tracked ultrasonic probe, a wireless tracking device that tracks the ultrasonic probe in space and an image data processor. The physical space data provides three-dimensional coordinates for each of the physical points. The image data processor includes a memory holding instructions. The instructions include determining registrations used to indicate position in image space and physical space; using the registrations to map into image space, image data describing the physical space of the tracked ultrasonic probe and the anatomical area of interest; and constructing a three-dimensional (3D) volume based on ultrasonic image data. The apparatus includes a storage medium that stores a plurality of 3D volumes acquired by the image data processor for later retrieval.
