摘要： PURPOSE: To provide an instrument capable of measuring the elastic characteristic of the local part of the artery and the heart wall by improving spatial resolution by using a frequency component up to a high frequency component. CONSTITUTION: Delay time T8 from the R-wave position 9 of an electrocardiogram 6 is supplied to an input waveform generator 7 to an excitor in advance, and a pulse waveform 11 of short width including the frequency component up to the high frequency component is generated at a timing 10 delayed by T from the R-wave of the electrocardiogram, and it is added on the excitor 12, and pulsative vibration 14 is applied to the bone 2 of a human body. In this way, vibration with high frequency component is propagated to the arterial wall and the heart wall, and micro vibration waves are measured at two points in a micro area desired to measure on the wall simultaneously by using an ultrasonic wave, and the propagation speed of micro vibration on which the tissue property of the micro area is affected and the elastic characteristic of the local part are measured with high accuracy in non-invasion fashion and substantially.
