title: [Limitations of detail recognition in radiographs due to threshold contrast values (author's transl)].
abstract: The minimal contrast was studied which can be recognised by the eye, using similar, neighbouring images under varying conditions of brightness. Subsequently the effect of contrast thresholds on the recognition of detail in radiographs has been examined.
