ABSTRACT:
In a method for identifying a living tissue in an ultrasonic diagnosis, the elasticity of a living tissue to be diagnosed is measured for each local small area by using ultrasound. Elasticity data for each kind of known living tissue is composed of an elasticity modulus frequency histogram in each local small area for each kind of living tissue and is managed in a data library. Regarding the elasticity data serving as the measurement results, the kind of living tissue to be diagnosed is identified by using the elastic data for each kind of known living tissue.
