Abstract From the Canadian patent

of the Invention, A method for determining the properties of a medium by activating temperature changing means to change the temperature of the medium from a first unperturbed temperature to a second different temperature during a first time period and permitting the temperature to relax to a final unperturbed temperature during a second time period. In a particular embodiment for example, the, intrinsic thermal conductivity and diffusivity of the medium are calculated during a selected portion of the first time period assuming an arbitrary value for the perfusion and the perfusion of, the medium is calculated during a selected portion of the second time period using the calculated …
