Abstract:
A method of reducing an undesired multiple-echo signal in ultrasound imaging, comprising the steps of:successively generating first 1-sound-line received signals from an output signal of a transducer;selecting one from among the generated first 1-sound-line received signals as a 1-sound-line received signal of interest;selecting second 1-sound-line received signals from among the generated first 1-sound-line received signals, the second 1-sound-line received signals including a 1-sound-line received signal preceding the 1-sound-line received signal of interest and also a 1-sound-line received signal following the 1-sound-line received signal of interest;averaging the second 1-sound-line received signals into a mean 1-sound-line received signal which corresponds to an undesired multiple-echo signal;subtracting the mean 1-sound-line received signal from the 1-sound-line received signal of interest to remove the undesired multiple-echo signal from the 1-sound-line received signal of interest.
