Augmented Reality for External Ventricular Drainage
External ventricular drainage (EVD) is a high-risk procedure that involves inserting a catheter inside a patient’s skull to drain cerebrospinal fluid and relieve intracranial pressure. To assist with this procedure, we have developed the Augmented Reality Catheter Tracking and Visualization Methods and System, which accurately projects both a catheter placed into the human brain through the skull, and a brain CT scan overlaid on the skull, onto AR glasses. Our technique uses a new linear marker detection method that requires minimal changes to the catheter and is well-suited for tracking other thin medical devices that require high-precision tracking.
