title: [The mean optical density in x-ray pictures: measurement methodology, results and parameters].
abstract: A simple testing method for defining the average density or the integral density of x-ray images is described. In a semiquantitative way the physicians in radiological offices can measure the proper integral density. The amount of scattered x-rays influences the integral density significantly. Proper values for testing the integral density of x-ray images are described.
