Phase Unwrapping of Color Doppler Echocardiography Using Deep Learning

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2023
Color Doppler echocardiography is a widely used non-invasive imaging modality that provides real-time information about the intracardiac blood flow. In an apical long-axis view of the left ventricle, color Doppler is subject to phase wrapping, or aliasing, especially during cardiac filling and ejection.
