Abstract
A non-invasive method of optical measurements is presented for determining at least one desired parameter of patient's blood. The method utilizes reference data indicative of the values of the desired blood parameter as a function of at least two measurable parameters. At least one of the measurable parameters is derived from scattering spectral features of the medium highly sensitive to patient individuality, and the at least one other measurable parameter is indicative of artificial kinetics of the optical characteristics of the patient's blood perfused fleshy medium. A condition of artificial kinetics is created at a measurement location, and maintained during a certain time. Measurements are carried out with different wavelengths of incident light during a time period including this certain time. Measured data is in the form of time evolutions of light responses of the medium corresponding to the different wavelengths. By analyzing the measured data, the at least two measurable parameters are extracted, and the reference data is utilized to determine the at least one desired blood parameter.
