IMPROVED INDICATION OF PATIENT SKIN DOSE IN RADIOLOGY

摘要

The field of the invention is diagnostic and interventional radiology and the invention is a dose indicator for use in a system for performing radiological procedures using ionizing radiation, for indicating a dose of radiation received in an area of skin by a subject during the radiological procedure, in which a zone is displayed which is representative of the extent of the area of skin exposed, and in which is a value of dose is displayed which is associated with the zone. The value of dose is representative of the dose of radiation received in the area of skin exposed during the procedure. The display is easily and quickly understood allowing the user of the system to swiftly understand the skin dose accrued by the patient. The use of zones provides an intuitive display.
