VIRTUAL COLONOSCOPY; REAL MISSES

Real-Time Volume Rendering for Virtual Colonoscopy

We present a volume rendering system that is capable of generating high-quality images of large volumetric data (e.g., 512) in real time (30 frames or more per second). The system is particularly suitable for applications that generate densely occluded scenes of large data sets, such as virtual colonoscopy. The central idea is to divide the volume into sets of axis-aligned slabs. The union of t...

3D Virtual Colonoscopy with Real-time Volume Rendering

In our previous work, we developed a virtual colonoscopy system on a high-end 16-processor SGI Challenge with an expensive hardware graphics accelerator. The goal of this work is to port the system to a low cost PC in order to increase its availability for mass screening. Recently, Mitsubishi Electric has developed a volume-rendering PC board, called VolumePro, which includes 128 MB of RAM and ...

Immersive Virtual Colonoscopy

Virtual Colonoscopy (VC) is an established noninvasive alternative to optical colonoscopy for colorectal cancer screening. Currently, radiologists examine VC data sets on a workstation computer using a single screen and simple navigation tools. The limited field of view increases examination time and introduces tedious interaction modalities. We propose conducting VC examinations inside an imme...

Virtual Colonoscopy Powered by VolumePro

Virtual colonoscopy is a non-invasive method for detecting polyps inside the colon. We developed a virtual colonoscopy system on a high-end 16-processor SGI Challenge with an expensive hardware graphics accelerator. To increase its availability for mass screening, we ported the system to a low cost PC. Since interactivity is critical in such an application, we took the advantage of the recently...
