Abstract:
A simple and practical method is suggested to evaluate and compare roentgenograms concerning optical density and contrast. The method is specifically indicated for research in which a metallic stepwedge penetrometer and a photodensitometer are used. A PC computer may be optionally employed for the mathematical and statistical processing of the data.
