Estimation of oxygen saturation from erythrocytes by high-resolution spectroscopic optical coherence tomographyJi Yi
Biomedical Engineering Department, Northwestern University, 2145 Sheridan Road, Evanston, Illinois 60208, USA
Opt Lett 35:2094-6. 2010..The result shows a reliable linear association between the SaO(2) derived from SOCT and the DS measurement, indicating this methodology has potential on in vivo applications to evaluate blood oxygenation...
Characterization of malignant brain tumor using elastic light scattering spectroscopyJianmin Gong
Department of Biomedical Engineering, Northwestern University, Evanston, IL 60208, USA
Dis Markers 25:303-12. 2008..We also demonstrate that all three classification methods discriminate between tumor and normal tissue and have the potential to identify and quantitatively characterize tumor-infiltrated brain tissues...
Structural length-scale sensitivities of reflectance measurements in continuous random media under the Born approximationAndrew J Radosevich
Biomedical Engineering, Northwestern University, Evanston, Illinois 60208, USA
Opt Lett 37:5220-2. 2012..9 nm to 2.07 μm (i.e., λ/13 to 3λ), μb is sensitive from 26.7 to 320 nm (i.e., λ/24 to λ/2), and the spatial reflectance profile is sensitive from 30.8 nm to 2.71 μm (i.e., λ/21 to 4λ)...
Measurement of the spatial backscattering impulse-response at short length scales with polarized enhanced backscatteringAndrew J Radosevich
