Virtual reality visualization of patient specific heart model

Background The diagnostic dilemma that arises with congenital cardiac anomalies is visualizing the 3-D complexity of a child’s heart with 2-D tools. The complicated intracardiac relationships and extracardiac connections make it challenging to diagnose the defect and plan treatment for the child. It has been demonstrated that it is difficult to reconstruct an accurate mental 3D model from 2D images [Guillot 2007], yet we rely on this imperfect modality to make critical surgical decisions. 3D printed models are proving to be highly valuable in improving the understanding of these complex defects, but require many resources. In this project we have explored 3D immersive virtual reality technology to provide deeper understanding and visualization of cardiac models and supplant the need for a physical printed model. Using stereoscopic 3D in the form of 3D displays on head mounted displays (HMDs) excellent intuitive model was created. Models were generated from patient specific MRI which was converted to format that was compatible with virtual reality rendering.
