Acquiring molecular interference functions of X-ray coherent scattering for breast tissues by combination of simulation and experimental methods
Background: Recently, it has been indicated that X-ray coherent scatter from biological tissues can be used to access signature of tissue. Some scientists are interested in studying this effect to get early detection of breast cancer. Since experimental methods for optimization are time consuming and expensive, some scientists suggest using simulation. Monte Carlo (MC) codes are the best...
متن کاملApplication of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues
ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....
متن کاملX-ray server: an online resource for simulations of X-ray diffraction and scattering
X-ray Server is a public project operational at the APS since 1997 with the goals to explore novel network technologies for providing wide scientific community with access to personal research results, establishing scientific collaborations, and refining scientific software. The Server provides Web-based access to a number of programs developed by the author in the field of X-ray diffraction an...
متن کاملNatural and synthetic prion structure from X-ray fiber diffraction.
A conformational isoform of the mammalian prion protein (PrP(Sc)) is the sole component of the infectious pathogen that causes the prion diseases. We have obtained X-ray fiber diffraction patterns from infectious prions that show cross-beta diffraction: meridional intensity at 4.8 A resolution, indicating the presence of beta strands running approximately at right angles to the filament axis an...
متن کاملResonant X-ray Scattering and Multiple Beam Diffraction in LaMnO3
Fig 1: The solid points give the location and shape of the (1 0 –4) resonant reflection in orthorhombic LaMnO3. Open circles display Mn Kα fluorescence from the same sample on a common energy scale. The vertical scale is arbitrary and the lines are guides to the eye. In conventional X-ray diffraction the beam scatters from all electrons in the unit cell, but in resonant diffraction at a forbidd...
