Abstract:
1. An ultrasonic diagnostic apparatus having an analyzing tool for analyzing lesion information of a tissue of an object by using RF signal frame data obtained from the object, the analyzing tool comprising: a displacement data calculating means for calculating displacement data by using RF signal frame data obtained in time-series; an elasticity data calculating means for calculating elasticity data comprising at least one of distortion and elasticity modulus at each point of a cross-section of an object as an examination target by using the displacement data; an elasticity image generating means for generating elasticity image data of the cross-section of the object from the elasticity data; an estimation data generating means for analyzing the elasticity data and an elasticity image, and generating plural estimation data containing a histogram of the elasticity data, statistical processing data and shape complexity of a diseased tissue; an estimation data selecting means for selecting parameters concerning estimation data relevant for classifying the elasticity image; and a multivariate analyzing means configured to classify the elasticity image into two or more groups by using the estimation data of parameters selected by the estimation data selecting means.
