Patent Issued for System for Identifying Radiation Zones in X-Ray Imaging

July 25, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- Siemens Medical Solutions USA, Inc. (Malvern, PA) has been issued patent number 8774361, according to news reporting originating out of Alexandria, Virginia, by NewsRx editors (see also Siemens Medical Solutions USA, Inc.).

The patent's inventors are Kargar, Soroosh (Lake in the Hills, IL); Lei, Weng (Mount Prospect, IL).

This patent was filed on March 6, 2012 and was published online on July 8, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "X-ray imaging equipment uses narrow collimated X-ray beams of high intensity radiation. Exposure of body parts to a primary X-ray beam may result in severe radiation burns in a matter of seconds. Exposure to scattered radiation also poses a hazard. Scattered radiation is produced when a primary X-ray beam strikes collimators, beam stops, samples or shielding. The intensity of scattered radiation is typically a couple of orders of magnitude less than that of the primary beam but is still capable of causing harm to a patient when radiation limits are exceeded.

"Radiation cannot be detected by human senses. Medical personnel who work in an angiography X-ray laboratory may be exposed to a lot of scattered radiation. Although, wearing radiation safety devices (such as lead apron, radiation safety glasses) reduces the amount of radiation, this only protects certain regions of the body and the safety devices are not 100% effective. A system according to invention principles provides guidance (such as visual guidance) to medical personnel indicating location of potential radiation zones in an X-ray imaging room."

Supplementing the background information on this patent, NewsRx reporters also obtained the inventors' summary information for this patent: "A system displays potential radiation zones in an angiography X-ray laboratory during an angiography procedure, for example, and identifies areas of potentially harmful radiation due to X-ray scatter in an imaging room. An input processor receives data identifying an emitted X-ray dose level applied to an area of a patient anatomy. An image data processor determines level of X-ray radiation dose scatter in different regions of an imaging room indicating regions of potentially harmful radiation, by calculating X-ray scatter dose at different distances from an irradiated patient area as being substantially in proportion to the size of the irradiated area and substantially inversely proportional to the square of the distance from the irradiated area. A visual alert system visually identifies areas of a room of potentially harmful radiation in response to the determination."
