摘要
Abstract
Objective: Body-surface electrogastrogram signals can be adopted in studies of gastrodynamic characteristics and diagnoses of functional gastric diseases. Collecting signals directly from the human body contains interference signal components can not be directly applied to clinical diagnosis characteristics of wavelet transform be decomposed into multi-scale and Methods: As a tool in matlab, using multi-resolution the signal containing the noise of the stomach would get a different band sub-band signals. We selected the number of sub-band for signal reconstruction, and these sub-band signals associated with the stomach. Results: We have obtained a more satisfactory EGG. Conclusion: Wavelet analysis is an easier and effective way to do EGG analysis in clinical diagnosis.关键词
