Abstract:
(Show)
A method is proposed and substantiated for determining the characteristic points of the pulse wave (sphygmogram) of the human radial artery, by numerical differentiation with the aid of the Tikhonov regularization algorithm. The results are given of experiments made to test the stability, to evaluate the accuracy of recovering the first and second derivatives, and to establish the sensitivity of the method to random distortions of the original data. Based on this method, we have solved one of the chief technical problems in the objectivization and automatization of the pulse diagnostics of Tibetan medicine, by the development and construction of an information-computing Tibetan medicine diagnostic complex, for processing medicobiological information in real time.
