PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic apparatus that, when tissue elasticity of a subject is measured, prevents the accuracy of tissue elasticity measurements from deteriorating due to image distortions.SOLUTION: When tissue elasticity of a subject is measured, an ultrasound diagnostic apparatus sets sound velocity by dividing the subject into plural pieces, processes reception signals output by a piezoelectric element array based on the set sound velocity, and performs tissue elasticity measurements using the reception signals processed based on the set sound velocity. |
