Abstract:
Electrogastroenterography is the promising method of examination of the motion activity of the digestive system. It is based on the measurement and further processing of bioelectric signals. During last years the progress in the development of electrophysiological methods of diagnostics is due to the computer processing of measuring signals. This paper is devoted to the aspects of organization of measurements in electrogastroenterography. In the paper, we present an introduction to the problem domain; analyze the information structure of a measuring signal; review the diagnostics parameters obtained as a result of spectral analysis of electrogastroenterography signals; discuss the tasks of automation of diagnostics.
We propose the new method of sampling of gastroenterograms. It considers the factor of the finite length of measurement sessions and spectral properties of signals. Representation of a signal as the finite sum of finite cardinal B-splines with integer degrees is used in the method. The computer experiment for testing the accuracy of signal reconstruction with parameters of measuring session used in electrogastroenterography was conducted.
