摘要： Embodiments for adaptively performing clutter filtering upon in an ultrasound system are disclosed. In one embodiment, the ultrasound system includes: an ultrasound data acquisition unit configured to transmit ultrasound signals to a target object and receive ultrasound echoes reflected from the target object to thereby acquire ultrasound data; and a processing unit configured to form a Doppler signal corresponding to each of a plurality of pixels constructing a Doppler mode image based on the ultrasound data, as well as to adjust coefficients of a clutter filter based on characteristics of the Doppler signal for each of the pixels for performing clutter filtering upon the Doppler signal.

摘要： There is disclosed an embodiment for adaptive clutter filtering. A signal acquisition unit transmits and receives ultrasound signals to and from a target object to output baseband IQ signals. A memory stores an error condition, a filter decision condition and information on at least two of filters for filtering the baseband IQ signals. A user interface receives a filter selection condition for selecting at least two filters among a plurality of filters stored in the memory. A processor extracts at least two of filters from the memory according to the filter selection condition and the error condition, decides a filter among the extracted at least two of filters and filters the baseband IQ signals by using filter coefficients of the decided filter.
