Abstract
By means of a read/write terminal patient identification data stored in a touch memory, an EEPROM, a bar code label or an RF tag are read or identification data are retrieved from a hospital identifictaion system (HIS). On the read/write terminal an examination type is selected from a displayed list of examination types. The patient identification data and the identifier of the selected examination type are associated, stored and transferred onto an RF tag provided on a cassette conveying a photostimulable phosphor screen or onto an RF tag that is attachable to the cassette. After exposure of the screen to X-rays, the RF tag and the photostimulable phosphor screen are read out and the radiation image read out of the screen is processed in accordance with processing parameters associated with the selected examination type.
