BabelVR


Babel VR is a free software tool for the HTC Vive that allows the import of 3D images from a variety of medical devices - different 3D image modalities including microscopes, ultrasound, Computer Aided Tomography (CAT), MRI scanners - so they can be viewed and interacted with in a virtual reality (VR) environment.

About BabelVR


Video 1: Babel VR - Abdominal Aortic Aneurism Planning

Preoperative assessment of 3D Ultrasound heart movies for mitral valve repair and left atrial appendage (LAA) closure (Jim Newton / Sam Dawkins, OUH, John Radcliffe Hospital) and phenotyping hypertrophic cardiomyopathy with multi-parametric cardiovascular magnetic resonance imaging (Betty Raman / Stefan Neubauer at OCMR). For this we are extending our BabelVR platform, which allows loading of 3D ultrasound, CT and MRI data and accurate measurements of anatomy. Feedback has been overwhelmingly positive and we plan to trial it preoperatively to understand patient anatomy and to potentially rehearse procedures. For example, we plan to assess the correct size of the sheath to block the LAA to prevent blood clots. Doing this preoperatively in VR means better assessment so the patient can be opened up for less time in theatre reducing chance of infection and mortality.
