The Dextroscope is a Virtual Reality (VR) environment designed to provide medical professionals with deeper understanding of a patient's complex 3D anatomical relationships and pathology. Although its main intended purpose is to enable surgeons to plan a surgical procedure (in particular, neurosurgery[1]), it has also proven useful in research in cardiology[2] ,[3] radiology and medical education.[4] The Dextroscope was designed to be a practical variation of Virtual Reality which introduced an alternative to the prevalent trend of full immersion of the 1990s.
