Scatter factor definition
Hepatocyte growth factor (HGF) or scatter factor (SF) is a paracrine cellular growth, motility and morphogenic factor. It is secreted by mesenchymal cells and targets and acts primarily upon epithelial cells and endothelial cells, but also acts on haemopoietic progenitor cells and T cells.Factors 4, 2, 3, and 7 are the Important Factors. Description of the Plot For this sample plot of the BOXBIKE2. DAT data set, there are seven factors and each factor has two levels. For each factor, we define a distinct x coordinate for each level of the factor. For example, for factor 1, level 1 is coded as 0. 8 and level 2 is coded as 1. 2. scatter factor definition
However, the scattering factor is modified by anomalous scattering if the incident wavelength is near an absorption edge of the scattering element. The Xray scattering factor is evaluated as the Fourier transform of the electron density distribution of an atom or ion, which is calculated from theoretical wavefunctions for free atoms.

The phantom scatter factor sp is defined as the phantom scatter dose contribution for a specified collimator defined field size and a specified field size at the phantom surface, normalized to unity for the reference irradiation setup.
where OF is the output factor, WF is the wedge factor, TF is the tray factor, and ISF is the inverse square factor. Wedges. Wedge angle: angle by which the isodose curve is turned by the wedge, typically at 10 cm; Hinge angle: angle between the central axes of two incident beams
A scatter factor is defined to account for the scatter in the material fatigue performance. The fatigue life variation of any given region of aircraft metallic structures is assumed to primarily correlate to the distribution of the equivalent precrack size of the fatigue crack initiators.
the total output factor, S cp, into two components, namely the head scatter factor, S c, and the phantom scatter factor, S p. The standard method for determining S p is to measure S c and S cp for symmetric fields and then divide the measured S cp by S c. Split of S cp into the two components S c and S p is important for dose and monitor unit
Definition and Terminology Output factor in air (OF, 13) is also called collimator scatter factor (Sc, 8), headscatter factor (H, 18), or output ratio in air (OR, 3). It is defined as a ratio of doses measured in a miniphantom between different collimator settings and a reference collimator setting
The Competitive Intelligence Report cMETHGF Inhibitors as of February 2010 provides a competitor analysis in the development pipeline of novel emerging inhibitors of cMET receptor tyrosine kinase (RTK) and its ligand hepatocyte growth factor (HGF) or scatter factor (SF) for treatment of solid tumors.
