ControlRad Systems is Granted U.S. Patent for Radiation Control and Minimization System

PHILADELPHIA, PA., Nov. 18 2013—ControlRad Systems Inc., a medical device company developing innovative products to dramatically reduce radiation exposure and risk for patients and physicians performing fluoroscopic procedures, has been granted a foundational patent from the U.S. Patent and Trademark Office for the Company’s radiation control and minimization system. The company has a broad portfolio of additional patents filed globally in key markets.

The company’s products are designed to allow physicians to identify a customized region of interest based on their attention during a procedure, either via pointing or via the automated detection of their gaze. In response to the attention of the physician, the system directs a dynamic collimator, or shutter, to instantly provide full dose radiation in the region of interest while providing a substantially lower dose of radiation to the peripheral field of view. The automated system capitalizes on the fact that the human eye has limited ability to see fine detail in the peripheral field of view, thus a substantially reduced dose of radiation can provide sufficient image quality in those areas without compromising perceived image utility.

U.S. Patent Number 8,445,878 was awarded to Allon Guez, PhD, co-founder and President of ControlRad Systems Inc., and assigned exclusively to ControlRad Systems, Inc.
