1. Use of perturbation and differential Monte Carlo methods to solve inverse problems in heterogeneous media

Author

Jerome Spanier, Vasan Venugopalan, Frédéric Bevilacqua, Carole K. Hayakawa, and Vanitha Sankaran

Subjects
Light propagation, Computer science, Attenuation coefficient, Monte Carlo method, Perturbation (astronomy), Image processing, Statistical physics, Inverse problem, Material properties
Abstract

We use Monte Carlo techniques to address inverse problems in heterogeneous media. The techniques we develop are general and do not rely on specific geometries or material properties.

2. Depth-Sectioned Imaging and Quantitative Analysis in Turbid Media Using Spatially Modulated Illumination

Author

David J. Cuccia, Bruce J. Tromberg, Anthony J. Durkin, and Frédéric Bevilacqua

Subjects
Optics, Materials science, Wave propagation, business.industry, Homogeneous, Physics::Medical Physics, Optical property, Physics::Optics, Spatial frequency, business, Quantitative analysis (chemistry), Diffuse optical imaging
Abstract

Experiments performed on heterogeneous and homogeneous tissue-simulating phantoms demonstrate that spatially modulated illumination enables depth-resolved imaging and wide-field optical property mapping in turbid media.

3. Quantitative analysis and imaging of subsurface heterogeneities using spatially structured illumination

Author

Frédéric Bevilacqua, Anthony J. Durkin, Bruce J. Tromberg, and David J. Cuccia

Subjects
Subsurface imaging, business.industry, Physics::Optics, Image processing, Tissue characterization, Iterative reconstruction, Structured illumination, Optics, Spatial variability, business, Quantitative analysis (chemistry), Computer Science::Databases, Geology, Structured light
Abstract

Illumination with structured light allows for subsurface imaging and the determination of the optical properties over a large area. Both the average and the spatial variation of the optical properties can be determined.

4. Monitoring breast tumor response to chemotherapy with broadband near-infrared tissue spectroscopy

Author

Dorota B. Jakubowski, Albert E. Cerussi, Frédéric Bevilacqua, Natasha Shah, David Hsiang, John Butler, Randall F. Holcombe, and Bruce J. Tromberg

Abstract

NIR tissue spectroscopy was used to monitor a breast cancer patient during three cycles of presurgical chemotherapy. Lesion values of lipid, water, deoxygenated and oxygenated hemoglobin changed significantly within the first week, and continued to change throughout therapy.
