[Modulation transmission function and detail recognition in tomograms (author's transl)]. 1977

J Meiler

Tomograms with linear movements and 40 degrees swing have shown that the usual T-modulation transmission function is inadequate and that the I-modulation transmission function is as significant as for plain films. Moreover, several selected modulation transmission functions are necessary. Even if resolution is high, detail recognition is reduced in relation to the threshold contrast. This is particularly true for the level of the cut and its close vicinity. On the other hand, pseudoimages are supressed by the threshold contrast.
