Abstract: Synchrotron-based scattered radiation form low-contrast phantom
materials prepared from polyethylene, polystyrene, nylon, and Plexiglas is used
as test objects in X-ray CT was examined with 8, 10 and 12 keV X-rays. These
phantom materials of medical interest will contains varying proportions of low
atomic number elements. The assessment will allowed us to estimate the
fluorescence to total scattered radiation. Detected the fluorescence spectra
and the associated scattered radiation from calcium hydroxyapatite phantom with
8, 10 and 12 keV synchrotron X-rays. Samples with Bonefil (60% and 70% of
calcium hydroxyapatite) and Bone cream (35 ∼ 45% of calcium
hydroxyapatite), were used. Utilized the X-ray micro-spectroscopy beamline
facility, X27A, available at NSLS, BNL, USA. The primary beam with a spot size
of the order of ∼ 10 μm, has been
used for focusing. With this spatial resolution and high flux throuput, the
synchrotron-based scattered radiation from the phantom materials were measured
using a liquid-nitrogen-cooled 13-element energy-dispersive high-purity
germanium detector.
