Abstract:

This research plans to develop enhanced contrast thermal acoustic imaging TAI technology for the detection of breast cancer by combining amplitude-modulated AM electromagnetic EM field excitation resonant acoustic scattering and advanced signal processing techniques. While EM-induced TAI possesses great promise the thermal acoustic signals tend to be weak. However when the tumor is excited into resonance via EM stimulation the effective acoustic scattering cross-section may increase by a factor in excess of 100 based on predictions for microsphere-based ultrasound contrast agents. Such an increase would truly be revolutionary making the EM-induced TAI technology a very promising candidate for routine breast screening. The image formation methods in the existing TAI systems are data-independent and have poor resolution and high sidelobe problems. We will devise adaptive image formation algorithms to achieve high resolution and excellent interference and noise suppression capability.
