[Quality assurance in x-ray diagnosis as specified in DIN 6868].

Regular quality control and safety assurance in diagnostic radiological systems are included in the new radiation protection regulations. The monitoring program for both the equipment and the film processor can enable the user to recognize loss of quality early. Variables in the film processing unit can be differentiated from faults in the X-ray equipment more easily, including its use. The cost and time spent in setting up a safety assurance program are justified by the increase in quality.
