Abstract
A method and system for non-invasive measurements in a patient's body in which several measurement sessions are performed on a measurement location. Each measurement session includes applying an external electromagnetic field to the measurement location, detecting at least two responses of the measurement location, and generating data indicative of the detected response. These responses are characterized by at least two different values of a controllable parameter. The measurement sessions include at least two measurement sessions carried out at a normal blood flow in the measurement location and at least two measurement sessions carried out at a condition of artificial kinetics in the measurement location. The first and second measured data are processed to determine a first relation between the first time variations and a second relation between the second time variations for the different parameter. that can be used to determine the at least one blood related parameter.
