ABSTRACT:
A fuzzy logic tissue/flow determination system receives echo amplitude, color amplitude, and velocity signals from an ultrasound imaging system. These values are applied to a set of fuzzy rules which quantify the amount by which the signal values vary from preset thresholds. The outputs of the fuzzy rules provide an indication of the plausibility that the echo signals represent a tissue or flow condition. The outputs from all the fuzzy rules are combined and de-fuzzified to produce a combined plausibility of the signals representing either a tissue or flow condition. The tissue/flow decision is made based on which plausibility is larger.
