Ultrasound diagnosis apparatus includes a transceiver unit, an adding processor, a filter, and an image processor. The transceiver unit insonifies an object injected with a contrast agent via an ultrasound transmission signal transmitted at a fundamental frequency f0 with at least two transmission rates. The adding processor adds a first component of the ultrasound echo signal and second component of the ultrasound echo signal. The first component is transmitted at a first rate of the at least two transmission rates and the second component is transmitted at a second rate of the at least two transmission rates. The filter suppresses at least a first frequency band of an addition result that is centered about a frequency 2.f0. The image processor then generates image data based on a suppressing result.
