Development of interactive three–dimensional autostereoscopic image for surgical navigation system using Integral Videography
3D auto stereoscopic Integral Videography (Ⅳ) has been proved ideal for use in biomedical applications such as image guided surgery and computer aided diagnostics.The purpose of this study is to develop a high-speed Ⅳ-based medical imaging system for intra-operative navigation and pre-operative diagnostics.The system consists of image acquisition,3D rendering and displaying,real-time positioning and other functions.Current Ⅳ rendering algorithm that takes advantage of Computer Graphics can visualize Ⅳ with high quality but low speed and is not suitable for clinical use.In this paper,we introduce a new Ⅳ rendering technique based on Light Field Rendering in which part of the computation is preprocessed and computational time is significantly reduced.This technique enables us to visualize high-speed,high-quality Ⅳ images that can be used in real-time tracking as well as user-interaction and should be of practical use in the biomedical field.
