Abstract:
An ultrasound diagnosis apparatus for imaging with a contrast agent, comprising:a transceiver unit for insonifying an object injected with a contrast agent via an ultrasound transmission signal transmitted at a fundamental frequency f0 with at least two transmission rates and receiving an ultrasound echo signal from the object based on the ultrasound transmission signal, wherein polarities of the ultrasound transmission signal are alternately inversed; an adding processor for adding a first component and a second component of the ultrasound echo signal, wherein the first component is received by the transceiver unit at a first rate of the at least two transmission rates and the second component is received by the transceiver unit at a second rate of the at least two transmission rates; a filter for suppressing at least a first frequency band of an addition result that is centered about a frequency 2Â·f0; and an image processor for generating first image data based on a suppressing result.
