| Outline of Final Research Achievements |
In this study, a multi-channel cardiac sound measuring system and the analysis method for diagnosis of heart diseases based on cardiac auscultation were developed. By cooperating with oversee research group we have collected a lot of heart sounds from various types of heart diseases. We have tried to analyze these four synchronous heart sound data in detail which has not been done by other researchers. In order to achieve high quality analysis resolution, we have developed several new signal processing techniques and algorithms for identifying heart diseases, also the GUI tools were developed for physicians or general users. Furthermore the proposed multi-channel heart sound analysis method and heart feature parameters were validated by analyzing the clinic data.
