Image-Based Guidance System for Intracranial Neurosurgery

Background•Problem:Neurosurgery is complicated, expensive, and not fully accessible

•Plan:Create a two-part image guidance system consist-ing of mechanical hardware and a web application

•Function: Will help neurosurgeons plan and perform mini-mally invasive and cost/time efficient surgeries

Design for MaskMake a web-based application for a previously developed 3D image rendering program• Program will creates a customized mask for the patient• Mask used to mark entry point

Web Based Interface To improve timeliness and accessibility of planning intracranial neurosurgeries, final product has the following features:

• Web accessibility• 2 GB file size• Create 3D model using CT/MRI Scans• Plan entry point, trajectory, and target points• Generate mask to 3D print

HardwareSpecifications:• Increase degrees of freedom and mobility• Pneumatic locks securely and hands-free, and withstands incidental forces• Maintains standard accuracy of 2 mm• Compatible with sterile fieldFeatures:• Stacks of washers and lock washers• Silicone tubing• Wave springs• Threaded ball (2)• Titanium threaded rod• Stainless steel enclosure• Probe holder

ResultsResults meet customer specifications for accuracy.
