Foetos: an expert system for fetal assessment

Foetos is an expert system designed to interpret fetal biophysical profile, contraction stress test, and nonstress tests. Foetos was built using the knowledge engineering tool GENIE, which adopts a mixed frame- and rule-based approach to represent the clinical knowledge in the field. Foetos includes diagnostic, prognostic, and therapeutic structures based on heuristic interpretation of such tests and contextual structures which relate interpretation to the overall clinical picture. The results of initial retrospective and prospective program validation show a substantial level of agreement between Foetos´ recommendations and clinical management. Interpretation of the results indicates that the obstetrical field could be an area of interest for the application of AI techniques.
