Orthodiagraphy was first introduced by Moritz thirty years ago. In his first article on this subject (Münch. med. Wchnschr., No. 29, July 17, 1900) he explains that because of the fact that roentgen rays originate from a point on the anti-cathode and from this point radially diverge, the shadow which they produce will necessarily be distorted in triangular proportion to the distance of the object from the anti-cathode. The teleroentgenogram will always be larger than the object. In order to overcome this error Moritz devised a method by which he could cut out all the rays except the true central
