Abstract
Color Doppler data is acquired only over a portion of the cardiac cycle, such as during diastole in order to increase the sensitivity of detection. Ultrasound system parameters such as clutter filter coefficience, temporal and spatial filter coefficients and demodulation frequencies may be altered only for a portion of the cardiac cycle to increase detection sensitivity, to improve myocardial border estimation and to avoid the loss of color Doppler image at end-diastole.
