Claim Text:
1. A method of ultrasound diagnosis that restores missed signals, the method being performed by an apparatus for ultrasound diagnosis and comprising: receiving by the apparatus for ultrasound diagnosis, a Doppler signal having at least one gap; obtaining by the apparatus for ultrasound diagnosis, a model parameter set of a first Doppler signal by using a period of the received Doppler signal before the at least one gap and obtaining by the apparatus for ultrasound diagnosis, a model parameter set of a second Doppler signal by using a period of the received Doppler signal after the at least one gap; synthesizing by the apparatus for ultrasound diagnosis, first Doppler information by using the model parameter set of the first Doppler signal before the at least one gap and synthesizing by the apparatus for ultrasound diagnosis, second Doppler information in a reverse temporal order by using the model parameter set of the second Doppler signal after the at least one gap; changing by the apparatus for ultrasound diagnosis, a temporal order of the second Doppler information to a reverse temporal order; and generating by the apparatus for ultrasound diagnosis, Doppler information for filling the at least one gap by cross-fading the synthesized first Doppler information and the synthesized second Doppler information having the changed temporal order, wherein the synthesized first Doppler information and the synthesized second Doppler information are artificial Doppler data.
