Progress in detection, analysis and application of new techniques to monitoring bowel sounds / 生物医学工程学杂志

ABSTRACT

The detection and analysis of bowel sounds are of importance to the diagnosis and treatment of gastrointestinal diseases. In this paper are summarized the recent advances in the detection and analysis as well as in the application of new techniques to monitoring bowel sounds. Several methods, including spectrum analysis, adaptive filtering, wavelet transform, principal component analysis, and artificial neutral network are mainly introduced. All of them are promising for feature extraction and automatic classification of bowel sounds.
