In-vivo method for determining and imaging temperature of an object/subject from diffusion coefficients obtained by nuclear magnetic resonance

Abstract From the Canadian patent

A method of determining and imaging the temperature or the temperature change of an object (human animal, liquid or solid) by nuclear magnetic resonance of molecular diffusion coefficients is disclosed which includes placing the object in a magnetic field Bo at a temperature To, subjecting the object to a first series of magnetic resonance imaging sequences to obtain first numerical values or images of molecular diffusion coefficients Do for individual points of the object or of a limited volume thereof, changing the temperature to a temperature T of a part of the object measured in step (b), or waiting for a spontaneous change to said temperature, subjecting the object to a second series …
