Abstract:
A method and an apparatus for selectively performing contrast harmonic imaging, tissue harmonic imaging and B-mode flow imaging with an ultrasound imaging system utilizes phase-coded excitation on transmit and selective firing-to-firing, i. e. , "slow-time", filtering on receive. "Slow-time" filtering in combination with transmit phases which change over the set of transmit firings results in different effective "slow-time" filters corresponding to the different harmonic modes within the reflected signal. The transmit phases and the "slow-time" filter weightings are designed to selectively enhance the desired modes while substantially suppressing other modes.
