Objective To evaluate the feasibility and accuracy of color M-mode Doppler flow propagation velocity (FPV) in assessment of the severity of aortic regurgitation (AR).
A guided-mode resonant filter (GMRF) based on the structure of anti-reflection (ar) thin film waveguide is proposed to realize three-primary-color filter with narrow-band.
