This paper describes application of the membership function acquisition method to an ultrasonic endoscopic image diagnostic system. This system is developed in order to differentiate between the medullary type gastric cancer and the intermediate type gastric cancer. The system was capable of estimating the possibility of medullary type by using texture characteristics of echoic images. This application revealed that the membership function acquisition method was applicable to construct fuzzy diagnostic support system for two-group differentiation.
