Testbed and Experiments for Focused Microwave Thermotherapy

In this paper, a testbed of a MW focusing system for non-invasive thermotherapy is presented. The proposed system provides a thermal dose at localized and deep-seated tissue for musculoskeletal disorder treatment applications. The proposed system operating at 915 MHz consist of 16 channel array antennas, a cylindrical shaped imaging tank which is filled with distilled water and a high power microwave transmitter. For focus at the targeted position, time-reversal technique is employed to find exiting parameters in proposed system. To verify the proposed system, experimental results to focus at targeted location in tissue-mimicking gelatin phantom is shown.
