摘要

PROBLEM TO BE SOLVED: To improve the determination accuracy of an osteoporosis screening using dental panoramic radiographs. SOLUTION: A threshold for tentatively determining "a low bone density" or "a normal state" is determined for every characteristic value by a threshold processing based on the fuzzy logic. Three fuzzy sets are set based on the thresholds. The connection weight of a three-layer neural network where the product of membership values to the respective fuzzy sets is defined as an input and "the low bone density" or "the normal state" is defined as an output is determined. When the characteristic value of a certain undetermined image is given, the product of the membership values to the fuzzy sets is input in the neural network to acquire the output of "the low bone density" or "the normal state".
