An ultrasound diagnostic apparatus includes a transducer array having a plurality of transducers arranged in an array, a transmission circuit which supplies an actuation signal to each transducer of the transducer array to transmit an ultrasonic wave toward a subject, a reception circuit which corrects a reception signal output from each transducer having received an ultrasonic echo from the subject in accordance with an angle between a reflection point in the subject and an acoustic radiation surface in each transducer to produce sample data, and an image producer which produces an ultrasound image on the basis of a sound ray signal obtained through phasing addition of sample data produced by the reception circuit. |
