A General Desktop Virtual Environment for Diagnosis and Treatment of Cerebrovascular Diseases

A general desktop virtual environment is developed in this paper. This novel system is composed by virtual environment generation module, data transform module, display module and human computer interaction module. With the support of this system, a noninvasive imaging modality for cerebral aneurysms and cerebral artery stenosis is implemented. The diagnosis and treatment of cerebral aneurysm and cerebral artery stenosis are conducted in the virtual environment. The results demonstrate that the location, size and shape of the lesion are more clearly and vividly than those in conventional 3D imaging. The VR system provides an advanced virtual reality environment that allows the neurosurgeon extremely understanding of the lesion's microanatomy. Compared with conventional 3D imaging, the speed and accuracy of cerebrovascular diseases diagnosis and treatment are improved by the VR system efficiently.
