Abstract

The electrogastrogram (EGG), a cutaneous measurement of gastric electrical activity, is a mixture of gastric slow waves and noise, which makes analysis of multichannel EGGs difficult. In this paper, a novel blind signal separation method with a flexible non-linearity is introduced and applied to extract gastric slow waves from multichannel EGGs. The results from both simulations and real EGGs obtained from humans show that the proposed method is able to extract gastric slow waves from multichannel EGGs. As a result, cleaned multichannel EGGs can be recovered to facilitate the analysis.
