Holographic Imaging Outscreens Flat Panel in Study

Researchers from Rush University Medical Center in Chicago will present results at ASTRO from a study found that holographic imaging has significant potential to achieve better quality in radiation treatment planning.
The study led by Rush, which also included Tufts-New England Medical Center, and Rhode Island Hospital/Brown Medical School, compared radiation treatment plans produced on a flat computer screen with those prepared using the Perspecta Spatial 3D system, developed by Actuality Systems, Inc. The Perspecta creates holographic images inside a 24-inch dome and displays images of the body, revealing a reportedly precise location of tumors in 3-D.
The study found that holographic images produced better 3-D relationships of anatomical and dose data than images from a flat screen display, and also determined that the location and size of over or under-dosed regions were easier to identify on Perspecta. The reviewers reported that Perspecta produced a better plan in six out of 12 brain cases and was better in the one lung cancer case and one breast cancer case studied.
The Perspecta Spatial 3D System has not received FDA approval and is not intended for use in clinical diagnosis, nor may it be used to prevent, diagnose or treat disease. In the medical field, Perspecta is offered to qualified research institutions only.
