A Model of Scattered Radiation
1999Scatter is a major degrading factor in the appearance of mammographic images therefore removal of its effects improves perceived image quality. Scattered radiation degrades mammographic images by imparting a smoothly varying energy component to the intensifying screen.

The preceding chapters have dealt with radiative heat transfer in nonscattering media only. This assumption is justifiable for many engineering radiative heat transfer calculations where the system under consideration is not to depart arbitrarily far from the non-scattering assumption.

Radiation and Scattering Processes
1991After the brief survey of atomic and molecular energy structures in Chaps. 2 and 3 we will now consider radiation and scattering processes by which atoms and molecules change their energy state. The processes are accompanied by the absorption or release of radiation, giving rise to spectra.

The absorption of radiation by a molecule and the consequent change of the molecule’s dynamic energy by a discrete amount, as discussed in connection with spectral lines in Chapters 2 and in 3.1, is a resonant and inelastic scattering process: resonant because the photon energy has to fit exactly the energy jump W n − W m of the molecule from a lower ...

Plasma Radiation and Scattering [PDF]
, 2010 Understanding of radiation and scattering processes in space plasmas is essential to correctly interpret the storm signatures in the solar spectrum. Radar scattering is also a powerful tool to probe the properties of the ionosphere.

Scattering of Radiation by a Plasma
Journal of Applied Physics, 1960By the use of a discharge tube, the ratios of positive column currents for the primary and secondary resonances were determined as a function of applied frequency. Acconding to Hershberger's argument, the ratios would be independent of frequency, however, the ratios were found to be frequency dependent. (M.C.G.)

The scattering of electromagnetic radiation from dielectric scatterers
Journal of Physics A: Mathematical and General, 1977The problem of electromagnetic wave scattering from arbitrarily shaped scatterers recently solved by using an integral equation formulation is extended to treat the case of scattering by infinite cylinders. The method is based on describing the internal field of the scatterer in terms of an independent set of plane wave functions.

Scattering of radiation in plasma
1996Until now, emission and absorption processes (including negative reabsorption in non-equilibrium plasma) have been considered as the main factors affecting transfer of radiation in astrophysical plasmas. Emission or absorption of photons or plasmons by charged plasma particles have been the basic processes of interaction of radiation with plasma in ...

Scattered Radiation in a Phantom from Diagnostic Quality Radiation
Radiology, 1965INFORMATION on the x-ray dose outside the defined field has long been of interest to the radiation therapist and to the hospital physicist working with him; this was provided in therapy isodose curves usually to a level of 5 per cent of the surface dose.

The resurgence of interest in detailed studies of light scattering phenomena is primarily due to the development of the laser. A laser is a nearly ideal source for scattering experiments, being both spatially and temporally coherent. In addition, the high intensity of radiation available has made possible studies of non-linear scattering effects which ...
