Abstract:
1. A method for gap filling in spectral Doppler ultrasound, the method comprising: acquiring spectral Doppler data representing a patient; identifying a gap in the spectral Doppler data; selecting a first sub-set of the spectral Doppler data adjacent to the gap; determining a second sub-set of the spectral Doppler data based on correlation of the spectral Doppler data of the first sub-set with the spectral Doppler data; selecting a third sub-set of the spectral Doppler data, the third sub-set selected relative in time to the second sub-set; filling the gap with a copy of the spectral Doppler data of the third sub-set; estimating a spectrum from the spectral Doppler data with the copy of the third sub-set in the gap; and displaying an image as a function of the spectrum.
