Title: Ultrasonographic instrument
Inventor: OKADA TAKASHI
IPC: A61B8/00
Filed: 2000-04-25
Abstract: PROBLEM TO BE SOLVED: To solve a problem of composite setting of a beam bearing suitable to measure a displacement of a blood vessel wall and a beam bearing suitable to rheometry. SOLUTION: A transmission and reception controller 14 steers a beam bearing of an ultrasonic wave, and transmits and receives the wave in each beam bearing. A feature signal detector 42 detects a strong feature echo for the blood vessel wall to be displayed at the received signal. An amplitude comparator 44 compares amplitudes of the feature signals of the blood vessel wall regarding the respective beam bearings. In this case, the amplitude depends upon an angle formed between the beam and the wall of the blood vessel. As the angle approaches toward a perpendicularity, the amplitude is increased. The beam bearing in which the amplitude becomes a maximum is selected as the beam bearing perpendicular to the wall, and used to measure the displacement of the wall. The beam bearing inclined at a predetermined angle thereto is used for the rheometry utilizing a Doppler shift.
