Page 6: About Gain Calibration
DR Detector Calibration | Calibrating the DR Detector | 6 About Gain Calibration Regular calibration of the DR Detector assures constant image quality. This calibration eliminates the effect of sensitivity deviations over the panel and/or corrects non-unifomity in the X-ray beam. The sensitivity deviations of pixels across the DR Detector are affected by the quantity and pattern of the effective X-ray dose on the detector. -

DR Detector Calibration | Calibrating the DR Detector | 10 Required material For calibration of all DR Detectors, apart from DR 18M, DR 24M and DX-D 25C, an Agfa calibration filter (Cu 1.5 mm) is required. For calibration of DR 18M and DR 24M, a calibration PMMA block is required. -
Page 11: Preconditions
DR Detector Calibration | Calibrating the DR Detector | 11 Preconditions • Clean the DR Detector (see the DR Detector user manual for instructions). • Make sure that all parts of the X-Ray system that may affect imaging (e.g. the DAP meter) are in their normal position and clean. -
Page 12: Procedure
To calibrate the DR Detector: 1. Log in to NX. To calibrate DR 10e C, DR 14e C or DR 17e C, you have to log in to a user account with adminis- trator rights. 2. Stop the NX software completely. - Page 13 Note If calibration fails again contact your local service representative. 10.Exit the Calibration Tool. 11.Start the NX software. In the Start menu, select All programs > Agfa > NX > Restart NX completely. Related information DR 10s and DR 14s Exposure Sequence...

To avoid overheating of the X-ray tube, limit the rate of exposures to two per minute. Calibrating DR 10s and DR 14s on DX-D 100 On a DX-D 100 mobile X-ray unit that is upgraded to support DR 10s or DR 14s, an extra step is needed to activate the DR Detector during calibration.
