ABSTRACT:
A method for increasing the valid data points produced by a digital filter. Input data is applied to a pair of filters that produce transients in response to different input data values. Output data from each of the filters is then combined to produce a data set with no transients. In one embodiment, the pair of filters have the same impulse response but the input data is applied to one filter in a first direction and to the other filter in an opposite direction. In another embodiment, the input data is applied to both filters in the same direction but the filters have inverted impulse responses. The present invention is particularly useful for minimizing a gap created when an ultrasound system alternates between different imaging modes. In addition, the present invention, can be used to increase the number of valid data points that are analyzed during color flow ultrasound imaging.
