Immersive Virtual Colonoscopy
نویسندگان
چکیده
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 immersive visualization environment, such as the fully enclosed Immersive Cabin (IC) or semi-immersive workstation display configurations. The additional projection surfaces, life-size visuals and stereoscopic rendering in the IC provide the radiologist with a more intuitive navigation experience and allow for better utilization of the direct and peripheral vision to pick up visual cues related to the presence of polyps. As a result, the doctor is able to examine more of the colon surface at any given time, reducing total time for the screening and increasing the sensitivity of the screening

Enclosed Five-Wall Immersive Cabin
We present a novel custom-built 3D immersive environment, called the Immersive Cabin (IC). The IC is fully enclosed with an automatic door on the rear screen, and thus very different from existing CAVE environments. Our IC, the construction of the projection screens and stereo projectors as well as the calibration procedure are explained in details. The projectors are driven by our Visual Compu...
متن کاملComparative Evaluation of User Performance for Modeling Tasks in Non-immersive and Immersive Virtual Environments
This work deals with modeling in immersive virtual environments. We present MuscleAssemblyLab (MAL), a tool to create musculo-skeletal layers for virtual humanoids. With modular interaction metaphors it supports various inputand output-devices ranging from classical desktop systems to virtual reality hardware. This enabled us to conduct a comparative user study between non-immersive and immersi...

This chapter discusses the implications of designing, perception, comprehension, communication and collaboration within the framework of an ‘Immersive Virtual Environment Design Studio’. It has been suggested that the unique properties of immersive virtual environments can empower designers to express, explore and convey their imagination more easily. For these reasons the very different nature...
متن کاملVirtual vs. optical colonoscopy in symptomatic gastroenterology out-patients: the case for virtual imaging followed by targeted diagnostic or therapeutic colonoscopy.
AIM To compare virtual colonoscopy with optical colonoscopy findings in symptomatic patients. BACKGROUND Computer tomographic colonography is an alternative to optical colonoscopy. Studies have shown that two-dimensional computer tomographic colonography does not have sufficient sensitivity. Three-dimensional computerized tomographic virtual colonoscopy compares well with optical colonoscopy ...
متن کاملInvestigating the Impact of Interactive Immersive Virtual Reality Environments in Enhancing Task Performance in Online Engineering Design Activities
The objective of this paper is to test the hypothesis that immersive virtual reality environments such as those achievable through the head-mounted displays, enhance task performance in online engineering design activities. In this paper, task performance is measured by the time to complete a given engineering activity. Over the last decade, a wide range of virtual reality applications have bee...
