In radiography, the abdomen of a patient is pressured to take photographs of the stomach clearly. By changing the form of the stomach, barium in the stomach shifts and spreads, so the clear image of the fold can be depicted. In a prone pose, pressuring abdomen is curried by towel put between a patient and the table. However, realization of the effective compression is difficulty, and taken time. In this study, we have developed the pressure bag using the soft mechanism. The pressure bag which is put between a table and a patient can pressure abdomen by air pressure. Pressure bag has high elastic and X-ray permeability, so it is suitable for compression of body under radiography. In pressure experiment for volunteers under radiography, the surface clear image of the stomach which was unobservable by conventional technique could be acquired efficiently.
