Summary The objective of this study is to establish the feasibility of fiber-optic dual-modality (morphological andmechanical) optical coherence tomography (OCT) for minimally invasive tissue characterization with microscopicresolution in the management of breast cancer. The long term goal is to improve the outcome of diagnosis and treatmentof breast cancer through OCT characterization of breast tissue. OCT is a cross-sectional imaging technology with highresolution and high imaging speed. Based on the fact that cancerous breast tissue has altered morphological andmechanical properties in microscale, we hypothesize that dual-modality OCT characterization on breast tissue willprovide more accurate differentiation between cancerous and normal breast tissue. We will develop and optimize a noveldual-modality OCT system that performs structural OCT imaging and quantitative optical coherence elastography (qOCE)on the same volume of breast tissue. To test the central hypothesis of this study, we will establish synergistic biomarkersbased on dual-modality characterization of breast tissue. We will validate that the biomarker including both morphologicalfeatures and tissue stiffness will lead to improved accuracy in the classification of breast tissue.
