Abstract :
The subcutaneous temperature distribution of a simulated hyperthermic treatment is retrieved from a set of noisy radiometric measurements at six equally spaced frequencies in the range 1.5¿6.5 GHz. Temperature profiles reconstructed by the combined use of both the singular value decomposition of the radiometric integral equation and Kalman filtering are shown.
