Abstract
A computed radiography patient identification system which matches a patient with an X-ray image of the patient stored in a stimulable storage phosphor. The system includes a patient identifying bar code uniquely identifying a patient; a stimulable storage phosphor identifying bar code uniquely identifying a stimulable storage phosphor and a portable bar code scanner. The bar code scanner is used to scan the patient bar code and the storage phosphor bar code when a patient is exposed to an X-ray which is stored on the stimulable storage phosphor. Preferably, a mobile X-ray source has an associated set of bar codes identifying X-ray examination types (chest, head, limb, etc.) and/or X-ray exposure conditions. The bar code scanner scans the examination type bar code at the time the X-ray of the patient is taken. The system includes a storage phosphor reader for converting an X-ray image stored in a storage phosphor into an X-ray image signal. The bar code identification of such stimulable phosphor is also read out. The storage phosphor reader receives from the portable bar code reader, information relating to patient identification, storage phosphor identification and examination typ…
