Claim One:
1. An ultrasonic diagnosis apparatus to evaluate the type and stage of liver disease comprising: a transmission and reception unit implemented by circuitry configured to transmit an ultrasonic wave to a region including at least part of a liver of an object and to receive an echo signal associated with the liver, via an ultrasonic probe; an image generating unit implemented by circuitry configured to generate an ultrasonic image of the liver in response to the echo signal associated with the liver; and a calculation unit implemented by circuitry configured to extract contour points and to calculate an approximate curve of the contour of the liver by using the ultrasonic image of the liver and to calculate a frequency distribution indicating an irregularity feature of the liver utilizing the positional relation between the approximate curve and the contour points of the liver, wherein the number of high-frequency components in the frequency distribution are utilize to determine the type and stage of the liver disease.
