PRASAD: an augmented reality based non-invasive pre-operative visualization framework for lungs

This paper presents a preoperative anatomical visualization framework, PRASAD (physically realistic adaptive and scalable anatomical deformation system), which combines a bio-mathematical representation of deformable lungs with real-time deformation and stereoscopic visualization technology. This framework provides a visualization of a dynamic patient-specific deformation of synthetic 3D anatomical models, that physicians can view from different viewpoints in a stereoscopic augmented reality environment for efficient diagnosis.
