A
virtual reality environment for integrating neuroanatomy was developed for
clarify the relationship among tumor mass and peri-tumoral microstructures
for facilitating neurosurgical trajectory design and optimizing therapeutic
outcome. Brain tumor and edema were segmented manually and reconstructed into
3D display. Fiber tracking was carried out via the Fiber Assignment by
Continuous Tracking algorithm with fractional anisotropy threshold of 0.2 and
angular limitation of 60 degree. The 3D stereo image was projected on the
non-depolarizing screen by two projectors with polarizing filter. Therefore,
the viewings of the users right and left eyes would be slightly different
and the stereo image would be produced from the users viewpoint with 3D
glasses.
