Two types of visualizations are provided to the surgeon on the workstation monitor. One is an enhanced reality visualization in which internal structures are overlaid on the video image of the patient. The video image is set up to duplicate the surgeon's view of the patient. Any segmented MR structures may be displayed at varying colors and opacities (see Figure 2).
A second visualization shows the location of the pointer tip in a 3D rendering of selected MRI structures and in three orthogonal MRI slices (see Figure 4). These visualizations are updated twice per second as the pointer is moved.
