Abstract: Thermoacoustic imaging (TAI) is a promising hybrid modality for breast cancer detection and a number of other applications utilizing the advantages of microwave and ultrasound. Breast cancer causes the second highest morbidity and the highest mortality among women. Early detection is crucial to increasing the survival rate of breast cancer. Although some clinically available imaging modalities like mammography, magnetic resonance imaging (MRI) and ultrasound imaging have been extensively utilized for breast cancer diagnosis, their insufficiencies have motivated interests in developing complementary imaging methods.
Microwave-induced thermoacoustic imaging (TAI) has been researched in the past decade and shown to be a potential non-ionizing technique for the detection of breast cancer. TAI develops an image of the internal features of a dielectrically lossy sample by employing generated acoustic waves from absorbed microwave energy in the sample owing to thermoacoustic effect. Malignant tissues, usually embracing higher dielectric loss, absorbing more energy and emanating stronger acoustic waves than the surrounding healthy tissues, may be distinguished in the image. As a hybrid imaging modality, TAI is endowed with the unique merit of high contrast inherited from microwaves and excellent spatial resolution inherited from ultrasound. This talk will highlight some of the novel research our group has done and promising results have been achieved.
