An ultrasound diagnostic apparatus generates an ultrasound image based on an ultrasound signal acquired by an ultrasound probe having an ultrasound transducer. The ultrasound transducer transmits an ultrasound wave to an observation target and receives the ultrasound wave reflected from the observation target. The apparatus includes: an analysis unit configured to generate analysis data based on the ultrasound signal received from the observation target and a correction unit configured to correct the analysis data using correction data based on first reference data and second reference data, the first reference data being obtained from an ultrasound signal received from a reference reflector by using the ultrasound transducer or another ultrasound transducer of a same type as that of the ultrasound transducer, the second reference data being obtained from the ultrasound signal received from the reference reflector by using still another ultrasound transducer of different type from that of the ultrasound transducer.
