New perspective on cancer

News

An advanced 3D display system developed for car designers may be beneficial in the treatment of cancer patients.

is exploring the use of the Perspecta Spatial 3D system to improve evaluation and planning of radiation treatments. This system, developed by Burlington, MA-based

, consists of a 20-inch dome that plugs into a PC to display full-colour and full-motion MRI, x-ray, CT, and nuclear medicine images in 3D.

"We believe Perspecta could have a significant impact on a physician's ability to review a treatment plan for radiotherapy," said Dr. James Chu, professor and director of medical physics for the department of radiation oncology. "Compared to a standard two dimensional display, the true 3D image enables physicians to work more precisely and efficiently."

The effectiveness of radiation therapy depends on the medical team's ability to concentrate high radiation doses to the tumours while minimising the doses to surrounding critical organs. Currently, oncologists have to look at hundreds of digital imaging slices, one at a time, to determine where the dose is hitting.
