| Abstract: | Objective： To make easy for the operators on the work of analyzing the heart sound signals, at the same time, for the purpose to improve unskillful operators analyze ability and diagnostic efficiency, at last to get the goal of fast diagnostic. Methods： We recommend STFT theory, then analyzed algorithm to design the programs by the way of LabVIEW2011,at last we realized to change one-dimensional heart sound signals into the form of intensity maps, which owns obvious recognition feature. Results： We have successfully used programs to realize the analysis on intensity maps, and also simplified judgmental process on illness. This method improves efficiency. Conclusion： Using the method described above can achieve the goal for improving the analysis method, it may work well as we thought before. |
