摘要：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.
主权项：1. A system for identifying areas of potentially harmful radiation due to X-ray scatter in an imaging room, comprising: an input processor for receiving data identifying an emitted X-ray dose level applied to an area of a patient anatomy; an image data processor for determining 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; and a visual alert system for visually identifying areas of the room of potentially harmful radiation in response to the determination.
