February 7, 2003 - Perspecta TM to be Shown as Expected Simplification of Tumor Localization, Surgical Planning, and Navigation

BURLINGTON, Mass. - February 7, 2003 - Actuality Systems, Inc., the leader in spatial 3D visualization technology, will demonstrate its Perspecta TM 3D System for advanced imaging of CT, PET, and MR data at the upcoming HIMSS 2003 conference, February 9-13 in San Diego, Calif. Actuality's Perspecta 3D System will be on display in booth #2237.

"Today, most medical imaging systems acquire 3D data that needs to be compressed to be viewed in standard displays terminals," said Gregg Favalora, the company's founder and Chief Technical Officer. "Perspecta projects 100 times more information than conventional 2D displays found in hospital reading rooms. Our interviews with physicists, radiologists, and practitioners of nuclear medicine imaging have revealed that Perspecta is expected to simplify tumor localization, historical patient reviews, surgical planning and navigation."

The Perspecta 3D System consists of a unique 360-degree spatial display and associated Perspecta software. It 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 clear polycarbonate dome.

Typical medical applications for the Perspecta 3D System include: nuclear medical imaging, such as using PET scans to locate tumors; medical intervention, such as stent insertion into blood vessels; mammography and biopsy, such as having 3D feedback on the precise location of a biopsy needle.

About Actuality Systems

Actuality Systems, Inc. develops, produces, sells, and licenses the Perspecta TM 3D System, a combination of hardware and software that permits 360-degree visualization, simulation, and collaboration. The system enables users to create high-resolution spatial 3D images that can be viewed from any angle around the 360-degree transparent dome - without the use of special goggles. Founded in 1997 in Cambridge, the firm has received venture funding and now operates from offices in Burlington, Mass., north of Boston. The Perspecta 3D System is designed for use in a range of applications including medical imaging, aerospace and defense, and oil and gas exploration.
