This is the most iportant technique in EUS examination.
Content of this paper is filling stomach with water during EUS examination in order to increase acoustic contact between stomach wall and transducer. Hisanaga performed this method for the first time in the world certainly. This is the most important discovery in EUS.

From No.25 Diagrammatic illustration of the transesophageal high speed rotating scanner. A small transducer in the esophagus is rotated through a full 360° through a flexible shaft by a motor at 15 to 50 cycles /s. Although the small trasducer is rotated with great speed in the patient's esophagus, no damage results because the transducer is safely enveloped in an oil bag.

The interatrial septum (IAS) is seen without dropout. AML = anterior mitral leaflet.
