An ultrasound method and system are provided. The ultrasound system (110) may transmit, to a target tissue (121), a pushing ultrasound signal for generating of a displacement (122), using a probe (114), receive a response signal from the target tissue in correspondence to a tracking ultrasound signal transmitted via the probe, detect (112) displacement information associated with the target tissue using the response signal, and generate (113) the acoustic radiation force impulse image based on the displacement information.
