Three-Dimensional near Infrared Imaging of Pathophysiological Changes within the Breast

Abstract

Diffuse Optical tomography is a non-invasive and non-ionizing medical imaging technique that can image functional properties of biological tissue using Near Infrared (NIR) light. Image reconstruction methods play an important role in characterizing the breast tissue optical properties. New reconstruction methods/algorithms which improve the quantitative and qualitative accuracy of NIR images are developed. At same time, existing methods/algorithms are optimized for the current clinical set up. Algorithms which will take an account of noise characteristics of the instruments were also developed to get an optimal estimate of breast tissue optical properties. Moreover, new methods for effectively using Magnetic resonance image information in NIR image reconstruction procedure were also developed to improve the total outcome of NIR functional images of breast.
