<p>A method of determining and imaging the temperature or temperature change of an object by NMR by placing the object in a magnetic field at an initial temperature Toi, subjecting the object to a first series of NMR imaging sequences to obtain first numerical values or images of molecule diffusion coefficients for individual points of the object and recording the first series of images, maintaining the object at a temperature T¿i? or waiting for a spontaneous change to the temperature, subjecting the object to a second series of imaging sequences and obtaining a second set of coefficients, comparing point-by-point the values or images of the two sets of diffusion coefficients to generate a third series of values or images representing temperature changes dTi and recording the third series of images for each point of the object.</p> |
