System for imprinting patient-identifying barcodes onto medical X-rays

摘要

An X-ray cassette 30 has a window 32 for mounting a back-lit LCD 34 to expose the film therein with patient identifying information in the form of a barcode. A strip of lead 38 opposite window 32 shields film 37 when cover 31 is closed. The LCD is activated after a sensor 56 connected to an X-ray tube 54 detects the discharge of X-rays. The patient identifying information may be read directly from the patient's bracelet 47 at the same time the X-ray is taken using barcode scanner 44.
