PET scans are invaluable for non-invasive, cross-sectional analysis of portions of the human body in-vivo. Although immensely useful, the imaging is slow, expensive, and limited to two real dimensions. A technique for the advancement of new hardware and software that makes the three-dimensional (3-D) visualization of body organs on a 3-D monitor possible, without the need for any headwear, is being developed. The objective is to construct a large scale monitoring system, 25 to 30 inches diagonal, for interactive, 3-D visualization and manipulation of PET-scan data. In Phase I, a preliminary, radionuclide visualization (RadioVis) 3-D monitor (with interface and visualization software and hardware) was demonstrated. All components were fully investigated in order to perfect the design of the RadioVis system, including a multiplexed holographic screen, projection optics, electronic boards, and digital micro-mirror device. In Phase II, the 3-D projection technology will be optimized and a 25 to 30 inch, diagonal 3-D RadioVis system with a 60 degree field of view, will be demonstrated. The system will integrate four unique modules for interactive operation: a RadioVis electronic processor, a 3-D RadioVis projector, a holographic multiplexed screen, and a feedback device. An evaluation of the system’s efficacy will then be conducted, using whole body, 3-D PET data for breast and other cancers.
Commercial Applications and other Benefits as described by the awardee: The RadioVis system should confer major benefits to many critical areas, including national security and nuclear control, health care, environmental monitoring, early disaster warning, education and training. This technology also offers additional benefits in reduced weight, volume, and cost when compared to other currently available technology.
