In this article, we refer to fog as the homogeneous scattering medium made up of molecules large enough to equally scatter all wavelengths as described in [1].
In scattering-based depth-resolving imaging modalities such as OCT, the reflective layers should also have homogeneous scattering characteristics to appear uniformly bright in the image, much like a metal film on glass would produce a laterally uniform brightness.
The 3D views confirm the earlier findings from the 2D slices: The control lung exhibits a strong homogeneous scattering pattern all over its volume, whereas the emphysema lung shows reduced scattering in the periphery and the fibrotic lung lacks scattering areas in the central, peribronchial regions.
A grid environment collects, integrates, and uses heterogeneous or homogeneous resources scattered around the globe by a high-speed network.
A 3-cm polystyrene block was used under the Petri dishes during each irradiation to allow homogeneous back-scattering γ-rays.
To correct for these modulations for our time-domain OCT system, we measured the signal from a homogeneous diffuse scattering phantom with known reference optical properties, μ t o and ρ o (where the subscript o denotes a property of the phantom).
In this particular work, the projections were simulated for the NM 530c by including all of the physical effects modelled using SIMIND, such as non-homogeneous photon attenuation, scatter in the object, scatter and penetration in the collimator, interactions in the CZT material, and the subsequent charge transport (including electron- and hole-trapping and charge diffusion).
An example for the distribution of cultured OC cells is shown in Fig. 3. Compared with fresh isolated OC cells, as seen in Fig. 1, the cultured cells are a homogeneous population on forward/side scatter.
The analytical investigation of the scattering coefficients confirmed that MgO-doped alumina has the scattering characteristics of the homogeneous matrix dispersed with spherical scattering grains, and that the existing model of light scattering in an alumina polycrystal is valid within a limited range of the wavelength/grain size ratio.
