From ref. 17 Horizontal scans through left kidney in a normal adult with intragastric high speed rotating scanner. A : Left kidney and abdominal aorta are seen clearly. If amplitude of near field is relatively low, pancreas is seen as anechoic space near stomach wall. B : With increasing amplitude of near field, pancreas assumes cloudlike shape.

From ref.18 Diagrammatic illustration of the transesophageal high speed rotating scanner. A small transducer in the esophagus is rotated througha a full 360° through a flexible shaft by a motor at 15 to 50 cycles /s. Although the small transducer is rotated with great speed in the patient's esophagus, no damage results because the transducer is safely enveloped in an oil bag.
From ref.18 Transesophageal high speed rotating scanner.
From ref.18 Transducer and commutator in oil bag. Sound energy is coupled to and from the transducer through the slip-ring commutator because of the full 360° rotation of the transducer.
From ref.18 Transesophageal cross-sectional echocardiograms in a patient with mitral stenosis. The cross section is horizontal and shows the heart as viewed from the cardiac apex. A : a frame during diastole and B : a frame during systole. Interatrial septum (IAS) is seen without dropout. AML= anterior mitral leaflet, ESO = esoophagus, IVS = interventricular septum, LA = left atrium, LV = left ventricle, PML = posterior mitral leaflet, RA = right atrium, RV = right ventricle, TV = tricuspid valve.

Hisanaga reported examination of humans in all papers. Apart from gagging, no serious complications were encountered in all transesophageal and transgastric examinations by Hisanaga. Medical Doctor Hisanaga himself developed all transesophageal and transgastric systems without help of any electric companies or organizations except that of Asako Hisanaga.
