[Computer diagnosis of gastric dysplasia and program design]

Two step processes were taken in computer diagnosis of gastric dysplasia. 1. 5 measurement values of dysplastic glandular tube obtained by using image analysis system were taken as the basis for judging the degree of dysplasia. Three glandular tubes of dysplasia were measured in each case. 2. Computer pathology diagnostic program using BASIC language ran in IBM computer. 5 parameters were input into computer for three stage-diagnosis. The first stage: 5 parameters were counted basing on three models to obtain three values which reflected the objective feature of the same glandular tube from different aspects. The second stage: diagnosis of a dysplastic glandular tube was obtained depending on the three values judged synthetically. Variate 'N' was introduced for controlling the first and second stage diagnosis of the three glandular tubes. The third stage diagnosis started as soon as N = 3. The third stage: diagnostic values of three glandular tubes were balanced and analysed depending on diagnostic criteria to reach the final diagnosis.
