Fuzzy Logic Approach to Identification of Cellular Quantity by Ultrasonic System

This paper introduces an ultrasound identification system for cellular quantity of artificial culture bone with fuzzy inference. In our method, first, we measure ultrasound wave. Second, we obtain the two characteristics of the amplitude and the frequency. The amplitude is calculated as the Peak to Peak value, and the frequency is calculated from frequency spectrum of transfer-function by using cross-spectrum method. Our fuzzy inferences system estimates the cellular quantity from these values. As an experimental result, our identification system could evaluate the cellular quantity in culture bone with high accuracy.
