A study of some key techniques of digitized virtual hand

Abstract

Objective To reconstruct anatomical structures and establish visible model of the hand and evaluate some key techniques of digitized virtual hand. Methods Three hands were scan and then perfused by self-curing denture acylic and cinnabar. With the datum from CT-scan of the specimen of perfused hand (cryopreserved 4-24 h), such anatomical structures as contour, bone, artery, extensor tendon, flexor tendon and nerve of hand were constructed by software of Mimics 10.01 and measured. Results The visible hand model based on anatomical structures was established and main anatomical structures were exactly showed. Each structure was displayed by the multiform solitude or combination. Vessel lumens was displayed hollow and fidelity. The hand nerve can the part demonstrate that can earnest reflect the normal human body nerve contour anatomy characteristic. Conclusion The visible hand model can provide 3D morphological data for clinical practice and research, as well as provide digitized model for virtual reality.
