A Preclinical System Prototype for Focused Microwave Breast Hyperthermia Guided by Compressive Thermoacoustic Tomography
Focused microwave breast hyperthermia (FMBH) can provide accurate and cost-effective treatment of breast tumors with low side effect. A clinically feasible FMBH system requires a guidance technique to monitor the microwave power distribution in the breast. Compressive thermoacoustic tomography (CTT) is a suitable guidance approach for FMBH. We developed a preclinical system prototype for the FMBH-CTT technique, mainly containing a microwave phased antenna array and an ultrasound transducer array. Experimental results demonstrate that the CTT technique can offer reliable guidance for the entire process of FMBH, i.e., from unfocused to focused microwave power distribution... Read more
