Abstract
In the gastrography, the high voltage radiography was used in order to make it possible to discern the walls of the stomach over wide area. The following conclusions were obtained : 1) High voltage radiography makes it possible to discern the walls of the stomach in the shadow of Barium, which is not observed clearly with the usual radiography. 2) In the part of the stomach in which the developer is more than 3 cm thick, it is impossible to discern the walls of the stomach even with the high voltage radiography. 3) The tube voltage of 140 kVp is most porper for this stomach high voltage radiography.
