Mixed-reality systems for enhancing stereotactic radiosurgery case planning

Embodiments of the present disclosure relate to methods, systems, and computer program products for rendering a three-dimensional anatoruical model in a virtual or augmented reality device. In various embodiments, a method includes reading at a remote seiver, a three-dimensional imaging study from a data store, where the three-dimensional imaging study includes a plurality of two-dimensional slices of at least one anatoruical strncture, optionally performing segmentation, at the remote seiver, on each of the plurality of two-dimensional slices, generating, at the remote seiver, a volumetlic model of the at least one anatoruical strncture based on the plurality of two-dimensional slices, scaling, at the remote seiver, the volumetrie model according to one or more display parameters of a virtual or augmented reality device, receiving, at the virtual or augmented reality device, the scaled volumetrie model; and rendering, at the virtual or augmented reality device, the scaled volumetrie model.
