| 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). | ||
