Adaptive clutter filtering method and ultrasound system for the same

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.
