There have been a lot of studies obout many factors on which the quality of a X-ray photograph depends. The geometrical relation between the blende and screen is one of tne factors. Here, the experiments were made to examine how the relation made an influence on the X-ray grame. Some ways of radiographing were examined under the following conditions. a) 1. the castte and blende were put closely. 2. the castte and blende were set at a some distance from each other. b) Setting apart the holder in front of the casette and attached it to the screen closely. (the way is so called S-type framework) The results obtained showed that the latter is excellent to the former both in density and sharpness. The S-type framewoyk means that the front screen and the blends are combined directly and the plate in front of the casette is put away.
