 As illustrated in Figure 1, the user wears the optical seethrough goggles (Juxtopia LLC, Baltimore, MD) and a helmet that supports a compact optical tracking system (Micron tracker, Claron Technology, Toronto, CA). The first step is a registration procedure (Fig 1), in which the surgeon uses a tracked probe to touch markers that were affixed to the patient prior to the preoperative imaging. A paired point rigid registration technique computes the transformation that aligns the preoperative data (i.e., tumor outline) to the real world.  As illustrated in Figure 1, the user wears the optical seethrough goggles (Juxtopia LLC, Baltimore, MD) and a helmet that supports a compact optical tracking system (Micron tracker, Claron Technology, Toronto, CA).

 After registration, the surgeon can see a registered preoperative model overlayed on the real anatomy using the optical seethrough goggles (Figure 2, which illustrates the concept with a skull model, rather than the tumor margin that would be used in an actual surgery). After registration, the surgeon can see a registered preoperative model overlayed on the real anatomy using the optical seethrough goggles (Figure 2, which illustrates the concept with a skull model, rather than the tumor margin that would be used in an actual surgery).
