More Information
Summary:The invention provides a blood flow signal characteristic parameter calculation method based on hemodynamics, and relates to the technical field of hemodynamics, a laser light source and a detector are arranged, the laser light source is used for irradiating a to-be-detected blood flow position, and the detector is used for receiving a blood flow signal; a normalized self-correlation algorithm is used for the blood flow intensity signals received by the detector, and a self-correlation function and a normalized value of the signal intensity are obtained; carrying out noise reduction processing on the strong self-correlation blood flow characteristic signal pair by utilizing a threshold value quantification method to obtain a clear blood flow characteristic signal pair; a clear blood flow characteristic signal pair parameter set under different sampling times is constructed, deviation judgment is conducted on the blood flow characteristic signal pairs, and the blood flow state is confirmed. 本发明提出了一种基于血流动力学的血流信
