Utilizing Gyroscope, a patient can be taken all kinds of positions at operator's will and radiographied from the directions selected by an operator. As shown in cases mentioned above, the stoma which was impossible to be demonstrated by a conventional apparatus can be illustrated as en-face and profile views. We believe that the method using theGyroscope developed by us are excellent for the radiological examination of the postoperative stomach.
Up to the present, it was difficult to take the double contrast picture of the gastric anterior wall with compression by routine method with conventional apparatus. However, we established the superiority of new radiographic techniques for the gastric anterior wall utilizing Gyroscope, and reported the methods with presentation of some clinical cases. Especially, method III is excellent in the demonstrability of mucosal pattern and it is valuable for the double contrast radiography of gastric anterior wall.
