ULTRASOUND DIAGNOSTIC SYSTEM AND INFORMATION PROCESSING DEVICE

摘要

In a metabolic syndrome examination, a probe is placed in contact upon a surface of an abdomen, and transmission and receiving of ultrasound is carried out. In a tomographic image which is formed thereby, a length a between the surface of the body and the abdominal aorta, and a length a1 between the outer edge of a visceral fat containing region and the abdominal aorta, are measured. An abdominal circumference length c is measured separately. Taking approximating an abdominal cross-section with an ellipse as a premise, a total area of the abdomen is computed from the abdominal circumference length c and the length a. An area of the visceral fat region is computed from the total area and the ratio of the length a1 to the length a as an area of a similar ellipse (partial area). An index which represents a visceral fat quantity is computed from this partial surface area and one or more personal parameter values for a subject.
