Breast Cancer Screening Using Photonic Technology
Abstract
The goal of the research is to develop a noninvasive modality that uses non-ionizing near-infrared (NIR) light for imaging and diagnosis of cancerous lesions of human breast. The imaging method involves illuminating the specimen with ultrashort pulses of NIR laser light and construction of images using two approaches: the shadowgram method, and the three dimensional (3-D) inverse reconstruction method. During this reporting period we set up: (a) time sliced imaging arrangements using an electronic time gate, and optical Kerr gates; (b) a spectroscopic imaging arrangement to explore the diagnostic potential of optical methods; and (c) a 3-D inverse reconstruction method that uses the diffusion approximation of the radiative transport theory as the light propagation model, and time-sliced two-dimensional transmitted light intensity data for inversion to obtain images of thick samples.
