Non-invasive microwave radiometry thermometry.

Near-field microwave radiometry and radiometric imaging are non-invasive techniques that are able to provide temperature information at a depth of up to several centimetres in subcutaneous tissues. They are based on the measurement of microwave electromagnetic thermal noise. This paper describes the basic principles, measurement methods and limitations of the techniques and the results of clinical studies, and it reviews recent progress.

An example of thermometry in volume by microwave radiometry.

We depict a method of determination of the size D depth z and temperature T0 + delta T of a cylindrical thermal structure embedded in an homogeneous glossy material, in the present case, water. A microwave radiometric image at 3 GHz points out the location of the thermal structure; its threshold provides the diameter D of the structure. The depth z derives from the ratio of the maximal radiometric intensities at 1.5 and 3 GHz. The combination of D,z and of the radiometric intensities gives delta T.

Introduction to correlation microwave thermography.

Correlation microwave thermography, a new process based on a coherent detection of noise, is able to improve the localization of the thermal gradients in the tissues. We explain the principles of this method and describe the first system which has been built and tested. Several experiments point out that with this process better spatial resolution and flexibility can be expected.
