【Abstract】 An experimental system in line with a microcomputer for measuring the sound velocity of biotic tissues by means of pulse is described. It has three approaches, i. e. reflection, transmission and liquid-immersion are available for option and the measurement in vivo can be performed rapidly. The relative error of measurement is better than ±O.3%. Some experimental data of sound velocity and resistance of normal and pathological parenchyma are given.更多还原
