Title: Ultrasonic color doppler video system and method for filtering ultrasonic doppler signal
Inventor: BAE MOO-HO
IPC: A61B8/06
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To accurately display a video such as a blood flowing speed or the like in real time by fixing a calculation section for calculating the power of an ultrasonic doppler signal and an average frequency based on outputs from a forward and reverse direction processing sections and providing these to an output for video displaying. SOLUTION: As the initial number of data filtered and eliminated by IIR filters 23 to 26 and 33 to 36 in forward and reverse direction processing sections 20 and 30, i.e., n1 and n2, is increased to a certain extent, the outputs of self correlation estimators 27 and 37 of both sides are made independent more while the influence of transient response on a clutter signal is gradually reduced. Here, by adding (or subtracting) the outputs of the self correlation estimators 27 and 37 to each other, an effect completely identical to non-elimination of data in the processing sections 20 and 30 is obtained. Thus, since there are no eliminated data, an ultrasonic color doppler video system accurately calculates power and an average frequency based on a relatively large number of data.
