This project aims to overlay a 3D model of a hip MRI onto of a patient to help guide the surgeon during a hip aspiration.

Project Overview

The client Dr. Tuo Peter Li, has requested a workflow design to convert MRI data in a DICOM file format into a usable format for augmented reality (AR). The workflow must incorporate an easy-to-use tracking system that can be set up quickly to align patient pelvic anatomy with the MRI scan in the AR space for use by orthopedic residents and radiologists. The device is intended to be used in hip aspiration procedures on children ages 3-9 years as a treatment for septic hip arthritis. The procedure requires doctors to remove fluid using an 18-gauge needle in either ultrasound or fluoroscopy guided apparatus. These imaging methods are challenging to coordinate in an emergency room and can pose health risks to children. The AR system will use patient MRIs and track real time movement during the procedure with minimal delay, and come with a prototype user interface (UI) for pediatric use. The tracking system will be tested for accuracy with a phantom that can accurately show targets and locate them in the AR space with a needle. The system must accurately show key features in the hip such as the hip joint capsule, fluid pocket, vessels, and neurovascular bundle. To ensure reproducibility, consistency, and accuracy the device will incorporate sensors to monitor accuracy and ensure the MRI is correctly overlaid on anatomy. The fabrication materials of the phantom and tracking system will stay within the budget of the client and the AR headset will be provided by the DI lab for fabrication until the workflow is complete.
