The Perspecta® Spatial 3D system, developed by Actuality Systems, Inc., creates holographic images inside a 24-inch dome. The full-color, full-motion system can display images of the body revealing the exact location of tumors in true 3D space.
A study led by Rush, which also included Tufts-New England Medical Center, and Rhode Island Hospital/Brown Medical School, found the Perspecta has significant potential to achieve better quality in radiation treatment planning. The study results are being presented this week at the annual meeting of the American Society for Therapeutic Radiology and Oncology in Philadelphia (November 5-9, 2006).
The effectiveness of radiation therapy depends on the medical team's ability to concentrate high radiation doses to the tumors while minimizing the doses to surrounding critical organs. Many of the planning tasks, such as beam placement, volume delineation, and plan evaluation are three dimensional (3D) in nature. However, current planning displays, showing 2D cross-sections or 3D renderings on a flat computer screen, are two dimensional (2D) in nature.
Actuality Systems "PerspectaRAD" Spatial 3D system generates true 3D imagery with a full 360-degree field of view. Using high-speed electronics, a CT scan is projected onto a screen spinning inside a 24-inch transparent dome. The screen, spinning at over 900 rotations per minute, forms a detailed, holographic image that can be viewed and manipulated from any vantage point around the 360-degree dome, by any number of users.
The study compared radiation treatment plans produced on a flat computer screen with those prepared using the Perspecta. Fourteen previously treated plans were replanned using Perspecta. The plans were then reviewed by four physicians who we
