The Team will design a virtual phantom overlay of a needle that will continually update its position to a hololens device during central venous access of the intrajugular vein.

Project Overview

Current methods of ultrasound-guided vascular access are severely hindered by poor visualization and poor spatial knowledge of the needle tip while it is inside the body. This requires the surgeon to guess where the needle is relative to the vessel, which increases the risk of trauma to the vessel and surrounding area. The engineering design team has been tasked with the creation of a real-time virtual overlay of the needle allowing for precise visualization of the needle tip even after insertion into the body. The goal for this semester is to create the virtual overlay of a needle in mixed reality via Microsoft's HoloLens 2 and to lay the groundwork for eventual integration with live ultrasound images. Dr. Von Bergen is trained in pediatric cardiac electrophysiology, the study and treatment of abnormal heart rhythms in pediatric patients and in adults with congenital heart disease. He completed his medical degree, residency and pediatric cardiology fellowship at University of Iowa Children's Hospital, Iowa City, IA, with some additional training in Ann Arbor, MI. He is board certified in pediatric cardiology. Dr. Von Bergen performs the majority of his procedures at American Family Children's Hospital, but has also traveled to hospitals in Iowa, South Dakota and Nevada, which provides him with one of the higher procedural volumes among pediatric electrophysiologists. He has an interest in the development, adoption and teaching of advanced procedural techniques to improve safety or effectiveness of the procedures he performs. Dr. Von Bergen treats patients who have been diagnosed with Wolff-Parkinson-White Syndrome or might be at risk for the syndrome
