Abstract
The possibility to visualize pathological tissues for example tumor neo-angiogenesis pattern-, using new X-ray imaging technique (such as Multi-Energy subtraction X-ray Imaging) is strictly related to an accurate knowledge of the X-ray absorption coefficients. Unfortunately, |i(E) values are partially derived from Monte Carlo simulation and known only for a little number of pathologies. A study of the attenuation properties of tissues was started at the University of Bologna in order to experimentally investigate their proprieties. Tissues X-ray attenuation curves are measured in a facility based on a Bragg monochromator with a lithium-fluoride crystal, to have beams with X-ray energies from 10 keV to 60 keV and energy resolution less than 2.0 keV. Different methods of analysis are implemented, starting from algorithms that can extract chemical-physical information from X-ray absorption measurements, such as effective atomic number and electron density.
