DISPOSITIF D'OBSERVATION À ULTRASONS, PROCÉDÉ DE FONCTIONNEMENT DE DISPOSITIF D'OBSERVATION À ULTRASONS, ET PROGRAMME DE FONCTIONNEMENT DE DISPOSITIF À ULTRASONS
An ultrasound observation apparatus (3) according to the present invention includes a frequency analysis unit (332) that calculates a plurality of frequency spectra, an analysis data correction unit (333) that generates analysis data indicating a relationship between a distance from the ultrasound transducer and an intensity of the frequency spectrum for each frequency component based on the plurality of frequency spectra and corrects the analysis data based on a correction amount that causes an intensity of reference data generated from a reference ultrasound signal to be constant regardless of the distance, a feature calculation unit (334) that calculates a frequency feature based on a frequency spectrum generated based on the corrected analysis data, and a feature image data generation unit (342) that generates feature image data for displaying the frequency feature calculated by the feature calculation unit along with the ultrasound image, in association with visual information.
