Abstract: Techniques and systems are described for providing modularity, tracking and simulation features of a mixed reality simulator. A modular approach to tracking systems, tracked instruments, and interchangeable modular physical models is described. Enhanced indicators and indicator interfaces improve imaging probe and instrument orientation and alignment with respect to a physical target, including but not necessarily within a combined physical and virtual system; these include anisotropy indicators, indicators of alignment in both in-plane and out-of-plane ultrasound or other imaging techniques, and perpendicularity indicators for better placement of probes and instruments over curved surfaces. A universal needle hub is described that integrates tracking system components and simulation feedback components usably with varying needle types.
