Multispectral microwave radiometry for temperature reconstruction inside biological media is considered. Radiometric data on simulated living tissues have been obtained with a multifrequency radiometer in the frequency range 1.5–3.5 GHz. Temperature retrieval has been modeled as the solution of a first-kind integral equation, based on the theory of radiative transfer. An example of temperature retrieval is reported.

Abstract
Multispectral microwave radiometry for temperature reconstruction inside biological media is considered. Radiometric data on simulated living tissues have been obtained with a multifrequency radiometer in the frequency range 1.5–3.5 GHz. Temperature retrieval has been modeled as the solution of a first-kind integral equation, based on the theory of radiative transfer. An example of temperature retrieval is reported. Results compare favorably with experimental measures.
