Abstract

Electrogastrography is a non-invasive method for obtaining information of electrical activity of the stomach. Due to non-invasiveness, it may be useful tool in routine diagnostic use, but because the nature of electrical activity of the stomach is not completely clear, it is not in everyday use. Electrical modeling may solve some unexplained questions. The authors present an electrical conductivity model, which takes into consideration the inhomogeneities of human body and anatomical shape of the stomach. Two three-dimensional models have been made, one based on the anatomical data of Visible Human, and other on CT images of a healthy subject. These models enable a more detailed analysis of the reflection of the effect of electrical activity of the stomach to the abdominal surface
