Abstract

CBET-0756338, Moghaddam The PI proposes combining two non-ionizing imaging modalities, ultrasound and microwave, to take advantage of the synergistic imaging properties that result. The ultrasound component will provide information regarding shape and location of unidentified tissue masses. The microwave component utilizes nonlinear time domain inverse scattering techniques and would provide quantitative information regarding the dielectric constant and conductivity of the tissue. Unlike the current systems that require verification, the proposed imaging system could provide a definitive diagnosis of the tissue mass /lesion significantly reducing the percent of false positive and false negative reports. When used in combination with the ultrasound shape functions it could provide an imaging system with increased resolution, spatial fidelity, and ability to quantify and characterize the tissue type. Initially the US and MW measurements will be taken simultaneously and independently during the early stages of algorithm development. The proposed imaging system could possibly provide a resolution of less than 5mm.
