Özet

Cardiac Doppler signals recorded from aorta valve of 120 patients were transferred to a personal computer by using a 16 bit sound card. Spectral analyses of aorta valve Doppler signals were performed for determining the Multi Layer Perceptron (MLP) neural network and Neuro-fuzzy system inputs. in order to do a good interpretation and rapid diagnosis, (AR) parameters of aorta valve Doppler signals classified using MLP neural network and Neuro-fuzzy system. Our findings demonstrated that 90% correct classification rate was obtained from MLP neural network, and 88.33% correct classification rate was obtained from Neuro-fuzzy system. Since we had limited number of patient, there is no significant performance difference observed between the two methods.
