Abstract: Focusing microwave hyperthermia, as a new non-invasive treatment, can be applied to the treatment of breast cancer. A prototype of conformal focusing microwave hyperthermia based on differential evolution algorithm is proposed. The operating frequency of the focusing antenna array is 2.45 GHz, and a real-time compressive sensing thermoacoustic imaging system is integrated to improve the visibility of focusing state. The focusing thermotherapy strategy of the prototype is expounded, and the focusing effect of the prototype is compared with that of the common prototype. Finally, joint simulation indicates that the focusing effect of the prototype based on differential evolution algorithm is better than that of the conventional prototype.

Key words: focusing microwave hyperthermia, differential evolution algorithm, thermoacoustic image, compressive sensing
