July 9, 2003 - Unique Optics Take Advantage of Rotating Projection Lens for High-Fidelity Spatial 3D Images

BURLINGTON, Mass. - July 9, 2003 - Actuality Systems, Inc., the world leader in spatial 3D visualization technology, announced today that it has been granted key patents on its spatial 3D technology in both the U.S. and in Taiwan.

The patents ( U.S. Patent No. 6,554,430 / Taiwan Letters Patent No. 162199) broadly describe a volumetric three-dimensional display system and specifically cover unique optics for Actuality's Perspecta TM Display. The patents teach the use of a novel rotating projection lens that ensures high-fidelity spatial 3D imagery which can be used for a variety of scientific applications.

"The key to getting high image quality is making sure that each two-dimensional slice of the composite 3D image is in crisp focus," said Gregg Favalora, the company's founder and chief technical officer. "With this technology, we've achieved exceptional clarity by using an image projection system with a rotating lens. The design allows us to tightly fold the system's optical path, providing a spatial 3D visualization product that is compact enough to use on a desktop or in confined spaces. This particularly addresses the needs of users in medical and military applications."

The Perspecta Spatial 3D System consists of a 360-degree Perspecta Display with powerful Perspecta platform software, a driver for the OpenGL® interface, and the firm's proprietary Spatial Rendering Kernel. An easy-to-use Software Developers Kit is available to members of the firm's Developer Program. The system enables users to render high-resolution spatial images that can be viewed from any angle as the user moves around the display. The display itself illuminates a record 100 million volume pixels, or "voxels," within a 20-inch transparent dome.

Typical applications of Perspecta include: real-time interventional medical guidance (such as biopsy or catheter localization), surgical planning, the fusion, registration, and visualization of CT, MRI, 3D ultrasound, and PET scans; battlespace visualization; air-traffic control; 3D game development; and homeland security applications such as visualizing the contents of freight or passenger luggage.

The patents are part of Actuality's growing portfolio of key technologies in advanced optical and holographic imaging. Both new patents are available for licensing.
