Analysis of Electrogastrogram Signal

Abstract

Now a day’s most of the people around the world face problems because of various eating and stomach disorders. Generally the procedure of endoscopy is followed for the detection of such problems but it is a tedious, expensive as well as an invasive technique and thus EGG is gaining immense popularity in this field as it is a cost-effective as well as a non-invasive technique. Due to these features EGG has become an attractive tool among researchers to study about the different kind of gastric disorders which can be analyzed with the help of simply placing the electrodes on the surface of the stomach of the patient. This project is divided into two parts. First is the collection of data which is followed by the second one which is analysis of the received EGG signal. The analysis of an EGG signal is difficult and visual interpretation of this signal is unreliable. Thus the analysis is done in MATLAB by application of various spectral analysis techniques like FFT, Welch, and Burg. Further the results obtained have been analyzed and compared for respective techniques applied.
