METHOD AND APPARATUS FOR ULTRASOUND DIAGNOSIS THAT REDUCES INTERFERENCE AND RESTORES MISSED SIGNALS |
摘要 |
A method and apparatus for ultrasound diagnosis that reduces interference and restores missed signals, is provided. The method of ultrasound diagnosis includes operations of receiving a Doppler signal having at least one gap; respectively obtaining model parameter sets of first and second Doppler signals by using Doppler signal periods before and after a start of the at least one gap; synthesizing first and second Doppler information by respectively using the model parameter sets of the first and second Doppler signals; and generating Doppler information for the at least one gap by cross-fading the synthesized first and second Doppler information. The apparatus includes a transformer for transforming received I and Q signals into stereo audio signals using a Hilbert transform; and a source separator which removes interference from the stereo audio signals by performing source separation on the stereo audio signals. |
