title: Quality assurance in radiographic imaging included in the film marking procedure.
abstract: Quality assurance for the radiographic processing can only be obtained by the aid of a continuous densitometric control. A method is described which uses a densitometric step wedge included in the marker equipment. It gives a constant radiation dose to the marking area. The step wedge is exposed simultaneously with the film marking. Disturbances in the radiographic procedure can thus immediately be detected.
