Abstract

An ultrasound diagnostic apparatus 1 sequentially displays ultrasound images of a plurality of continuous frames during imaging on a display unit 8, and includes a measurement target recognition unit 9 that automatically recognizes a measurement target included in an ultrasound image of a present frame displayed on the display unit 8, a measurement algorithm setting unit 12 that sets a measurement algorithm for the measurement target recognized by the measurement target recognition unit 9, and a measurement unit 10 that measures the measurement target based on the measurement algorithm set by the measurement algorithm setting unit 12 and displays a measurement result on the display unit 8 to be superimposed on the ultrasound image of the present frame.
