Abstract

For diagnosis or monitoring of gastric or lung conditions, particularly H.pylori infection or tuberculosis, a gas sample is passed to a multiplicity of chemical sensors which generate electrical outputs. These outputs are passed to a data processing system, preferably a hybrid intelligent system employing a search optimisation engine of genetic algorithms and a multiplicity of ne ural networks. This determines distinctive patterns characteristic of particular disease states.
