Neuroendoscope Navigation
Objective
The Neuroendoscopy Navigation Project aims to develop a accurate Navigation Module in Slicer 3D for Neurosurgery. In this scope the user is able to navigate virtual.
Overall Goals of the Work/ Significance and Patient Impact
We focus on flexible-neuroendoscopy devices, which have significant advantages over conventional rigid scopes but are difficult to navigate due to their flexibility-in fact, we have observed that surgeons frequently become disoriented when using these devices. In addition, it can be extremely difficult to target a region of interest safely using optical images alone. The endoscopic images show only the internal surface of the cavity in which the scope is placed and cannot be used to directly locate anatomical structures or pathologies that lie hidden beyond this surrface. We will develop technologies for real-time electromagnetic navigation of flexible-neuroendoscopy.
Such a navigation system will provide the following benefits in the two fields of neurosurgery:
- the mobidity and mortality rate of the endoscopic third ventriculostomy (ETV) procedure, which has become the method of choice for the treatment of obstructive hydrocephalus, will be improved; and
- the indications for neuroendoscopic surgery will expand to include deep-seated intra-parechymal brain tumors that cannot be teated by conventional means.
Although histological diagnosis is mandatory for such tumors, safe and accurate procedures for biopsy have not been established. Neuroendoscopic surgery for deep-seated brain tumors may produce a safer and more effective alternative to traditional stereotactic biopsy. Additionally, most of the deep-seated brain tumors are associated with hydrocephalus. Endoscopic interventions using this navigation system will be able to archive all the necessary objectives, such as tissue diagnosis and cerebrospinal fluid diversion. In near future, we should be able to aim from tumor biopsy to total removal for deep-seated tumors developing this navigation system.
