Microwave Thermal Imaging by Radiometry

Microwave radiometry appears to be well suited for treating thermological investigations devoted to moderately deep seated tissues. These investigations are used in diagnosis and follow up methods (for example in the detection of thermogen tissues, or inflammations such as those consecutive to acute ionization radiations...) and also for the monitoring of local heating in hyperthermia. We emphasize a process leading to radiometric imaging, present images obtained in medical examinations, and present in which way we determine the characteristics of a compact thermal volume by the processing of radiometric data obtained at two frequencies.
