ABSTRACT:
A method for determining a flow rate of a substance or a thermo-contrast agent in an object including a surface and an upstream region, and the method comprising the steps of (a) providing the upstream region with a thermo-contrast agent; (b) obtaining successive temperature readings of at least a part of the surface of the object; (c) generating a temperature response curve from the temperature readings; (d) extracting a parameter from the temperature response curve; and (e) determining the flow rate from the parameter.
