Contrast Enhancement for Thermal Acoustic Breast Cancer Imaging via Resonant Stimulation
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.
