Elastic light scattering from nucleated blood cells: rapid numerical analysis.
A model is presented to calculate the light-scatter properties of nucleated blood cells which are mimicked by two concentric spheres. The light-scatter characteristics were derived from the Rayleigh-Debye-Gans approximation and by simultaneous application of field averaging of the internal field and modification of the propagation constant inside the different cellular compartments. It is shown...
متن کاملFractal mechanisms of light scattering in biological tissue and cells.
We use fractal continuous random media to model visible and near-infrared light scattering by biological tissue and cell suspensions. The power law of the reduced scattering coefficient, the anisotropy factor of scattering, and the phase function are derived with good agreement with experimental results. Implications for spectroscopic tissue diagnosis are discussed.
متن کاملA study of high frequency ultrasound scattering from non-nucleated biological specimens.
The high frequency backscatter from cells with a nucleus to cell volume ratio of 0.50 cannot be adequately modeled as a homogeneous sphere. It was hypothesized that the cytoplasm of such cells is of fluid nature. This work attempts to model the ultrasound backscatter (10-62 MHz) from some non-nucleated biological specimens. This was done by measuring the backscatter response from individual sea...
متن کاملMeasuring Spatially- and Directionally-varying Light Scattering from Biological Material
Light interacts with an organism's integument on a variety of spatial scales. For example in an iridescent bird: nano-scale structures produce color; the milli-scale structure of barbs and barbules largely determines the directional pattern of reflected light; and through the macro-scale spatial structure of overlapping, curved feathers, these directional effects create the visual texture. Mill...
متن کاملStatic Laser Light Scattering Studies from Red Blood Cells
A homemade Static Light scattering studies has been used to determine angle resolved scattered intensity for different polarization states of the incident laser light. Classical light scattering set ups are being used to study morphological aspects of scatterers using simple set ups using low power lasers. Red blood cells form rather interesting as well as a challenging system for scattering ex...
