Abstract
An ultrasound system produces composite color flow images of tissue samples. To reduce image flicker, the ultrasound system stores the data required to produce two sequential color flow images and computes a series of interpolated images that are displayed between the actual color flow images. A piece-wise interpolation function is used to create the interpolated images in order to prevent artificial smoothing of the image data. In addition, the ultrasound system quantizes the ultrasound data used to compute the interpolated images in order to reduce the amount of memory required to store the data for the sequential color flow images.
