Abstract
Virtual Tomographic Reflection (VTR) is a new augmented real- ity technique that allows users to view volumetric image data using an interaction paradigm based on medical ultrasound. VTR is es- sentially a "virtual" version of the Sonic Flashlight, a a device that permits real-time in situ visualization of ultrasound images by re- flecting calibrated images displayed on a flat-panel monitor from a partially transparent half silvered mirror [13], where the actual ul- trasound scanner is replaced by an optical tracking / computer sys- tem capable of generating cross-sections through stored image data. The design of this system was motivated by the need to conduct psychophysical and accuracy analysis of the real Sonic Flashlight in a highly controlled artificial environment [12]. Here we present the fully developed version of our Virtual Tomographic Reflection (VTR) device and describe the overall system architecture as well as a highly accurate method for calibrating the system. In addition, we describe proposed psychophysical studies and the utility of VTR as a tool to explore very large medical image datasets derived from the National Library of Medicine Visible Human project.
