摘要： An ultrasonic diagnosis apparatus includes a frequency analyzing unit that analyzes frequencies of received ultrasonic sound waves and calculates a frequency spectrum; a feature data extracting unit that performs approximation and correction with respect to the frequency spectrum calculated by the frequency analyzing unit so that there is a decrease in the contribution of attenuation, which occurs due to the reception depth and the frequency of ultrasonic sound waves being propagated, and extracts feature data of the specimen; a storing unit that is used to store feature data of frequency spectrums, each being extracted based on ultrasonic sound waves reflected from one of a plurality of known specimens, and tissue characterizations of the known specimens in a corresponding manner; and a tissue characterization determining unit that determines tissue characterization of a predetermined area of the specimen by referring to feature data, which is stored by the memory unit in a corresponding manner to the tissue characterizations of the plurality of known specimens, and by referring to the feature data extracted by the feature data extracting unit.
