Correlating the Morphological and Light Scattering Properties of Biological Cells
Moran, Marina (East Carolina University, 2013)The scattered light pattern from a biological cell is greatly influenced by the internal structure and optical properties of the cell. This research project examines the relationships between the morphological and scattering ... -
Label-free classification of cultured cells through diffraction imaging
Dong, Ke; Feng, Yuanming; Jacobs, Kenneth M.; Lu, Jun Q.; Brock, R. Scott; Yang, Li V.; Bertrand, Fred E.; Farwell, Mary A.; Hu, Xin-Hua (2011-05)Automated classification of biological cells according to their 3D morphology is highly desired in a flow cytometer setting. We have investigated this possibility experimentally and numerically using a diffraction imaging ... -
Quantitative analysis and comparison of 3D morphology between viable and apoptotic MCF-7 breast cancer cells and characterization of nuclear fragmentation
Wen, Yuhua; Chen, Zhan; Lu, Jianfen; Ables, Elizabeth Tweedie; Scemama, Jean-Luc; Yang, Liv. V.; Lu, Jun Q.; Hu, Xin-Hua (2017-09-08)Morphological changes in apoptotic cells provide essential markers for defining and detection of apoptosis as a fundamental mechanism of cell death. Among these changes, the nuclear fragmentation and condensation have ... -
Resolving power of diffraction imaging with an objective: a numerical study
Wang, Wenjin; Liu, Jing; Lu, Jun Q.; Ding, Junhua; Hu, Xin-Hua (2017-05)Diffraction imaging in the far-field can detect 3D morphological features of an object for its coherent nature. We describe methods for accurate calculation and analysis of diffraction images of scatterers of single and ... -
uantitative characterization of turbidity by radiative transfer based reflectance imaging
Hu, Xin-Hua; Tian, Peng; Chen, Cheng; Jin, Jiahong; Hong, Heng; Lu, Jun Q. (2018-04-04)A new and noncontact approach of multispectral reflectance imaging has been developed to inversely determine the absorption coefficient of μ a , the scattering coefficient of μs and the anisotropy factor g of a turbid ...
