The MCNP Monte Carlo radiation transport code was used for calculation of scatter distribution and scatter-toprimary ratio (SPR) for different tube voltages, phantom thicknesses and field size in diagnostic radiology. Subsequently, the effect of grid’s design parameters such as strip density, grid ratio, interspace material and lead-tointerspace ratio on scatter rejection was investigated by ca...

An approach reported recently by Alexandrov et al. 1 on optical scatter imaging, termed digital Fourier microscopy (DFM), represents an adaptation of digital Fourier holography to selective imaging of biological matter. Holographic mode of recording of the sample optical scatter enables reconstruction of the sample image. Form-factor of the sample constituents provides a basis for discriminatio...

In this paper, we propose a Two-dimensional locality preserving projection based on maximum scatter difference (2D-DLPP/MSD). 2D-LPP/MSD use additive principle to preserve the locality by maximizing the between-class scatter and within-class scatter instead of using multiplicative principle of 2D-DLPP. Theoretically, we also discuss the influence of balance factor α on performance and reveal th...

Within the professional literature, it is frequently suggested that interpretation of cognitive profile scatter may be useful for clinical and/or diagnostic decision-making. To wit, Hale and colleagues (2008) posit that cognitive scatter is a defining characteristic of learning disabilities and that individuals with learning disabilities may have higher levels of scatter than normal controls. T...

Atomic substitution in alloys can efficiently scatter phonons, thereby reducing the thermal conductivity in crystalline solids to the "alloy limit." Using In0.53Ga0.47As containing ErAs nanoparticles, we demonstrate thermal conductivity reduction by almost a factor of 2 below the alloy limit and a corresponding increase in the thermoelectric figure of merit by a factor of 2. A theoretical model...

Inappropriate expression of Met, the receptor for hepatocyte growth factor/scatter factor, has been implicated in sarcomagenesis via an autocrine mechanism. Sarcomas occur at high frequency in individuals with Li-Fraumeni syndrome as well as in p53-deficient mice. Here we show that these tumors express high levels of Met. Moreover, late passage fibroblast cell lines established from p53-deficie...

Introduction: One of the most important parameters in x-ray CT imaging is the noise induced by detected scattered radiation. The detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. The magnitude and spatial distribution of the scattered radiation in x-ray CT should be quantified for development of robust scatter...
