Abstract A storage phosphor radiography patient identification system which matches a patient with an x-ray image of the patient stored in a storage phosphor. The system includes a patient identifying bar code - uniquely identifying a patient; a storage phosphor identifying bar code uniquely identifying a 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 storage phosphor. Preferably, a portable x-ray source has a chart having sets of bar codes identifying x-ray examination type information. The bar code scanner scans the examination type bar codes at the time the x-ray of the patient is taken. The storage phosphor has a non-volatile read/write memory adhered to it. The bar code scanner has a memory probe which transfers the patient ID, storage phosphor ID and exam time information from the bar code scanner to the storage phosphor memory. The system includes a storage phosphor reader for converting an x-ray image stored in a storage phosphor into an x-ray image signal and for reading the bar code identification of the storage phosphor. The storage phosphor reader receives from the storage phosphor memory through an internal memory probe, information relating to patient identification, storage phosphor identification and examination type and matches the patient identification and examination type with the x-ray image signal.
A storage phosphor radiography patient identification system comprising: patient identifying bar code means adapted to be located with a patient for identifying a patient; a storage phosphor cassette means for containing a storage phosphor which stores an x-ray image of a patient, said storage phosphor cassette means having storage phosphor identifying bar code means for identifying said storage phosphor and further having adhered to it a read/write non-volatile memory contained in a self adhesive electrically conductive cylindrical container; x-ray examination type bar code means locatable with an x-ray source for identifying x-ray examination type characteristics of an x-ray image stored in said storage phosphor, wherein said x-ray examination type bar code means includes a first set of bar codes identifying unique body parts of a patient and a second set of bar codes identifying x-ray exposure conditions; hand-held bar code scanner means, having memory, for scanning said patient identifying bar code means, said storage phosphor identifying bar code means, and a bar code from each of said first and second sets of said x-ray examination type bar code means at the time said storage phosphor means is exposed to an x-ray image of a patient, to produce patient identifying information, storage phosphor identifying information, and x-ray examination type information which is stored in said memory; wherein said bar code scanner means is further provided with a probe, connected to said memory for transferring the identifying information to said read/write non-volatile memory, adhered to said storage phosphor means; storage phosphor reader means for converting a stored x-ray image in said storage phosphor into an x-ray image signal, said storage phosphor reader means having, a) bar code reader means for reading said storage phosphor bar code identifying means to produce a storage phosphor identifying signal matched with said x-ray image signal, and b) a read/write memory probe for contacting said read/write memory and for transferring said identifying information stored in said memory to said storage phosphor reader means for matching said transferred information to said x-ray image signal.
