Abstract

Systems and methods facilitating training in clinical procedures via mixed reality simulations are disclosed. Such a system can comprise a physical model and a virtual model of an anatomic region associated with the procedure, wherein the virtual model associates tissue types with locations in the physical model. The system can include a tracking component that tracks locations of at least one clinical instrument relative to the models, and an anatomic feedback component that can produce perceptible changes in the physical model based on the interaction between the instrument and virtual model. A clinical device interface can detect outputs of clinical devices like electrical signals, pressure or flow, wherein feedback to the physical model depends on the tracked position of a clinical device and output from the same or different clinical device. Another component can generate feedback effects to the clinical device. Aspects can simulate anesthesiology procedures like local nerve blockade.
