Silicon detectors for dual energy X-ray medical imaging
The project is intended to the development of an X-ray detecting system for
dual-energy medical imaging applications.
Dual-energy techniques are based on the collection of two images of the
same object at two different X-ray energies, thus allowing to increase
the contrast of the interesting details in some medical examination
such as mammography and coronary angiography.
Since image post-processing capabilities are required to fully exploit the
advantages of the double energy, a digital detecting system is best suited
for such applciation.
The detecting system is based on silicon microstrip detectors and full-custom
ASICs for single-photon counting.
It is intended to be used with a compact source which provides quasi-monochromatic
X-ray beams in the energy range between 10 and 40 keV featuring Bragg diffraction
of photons from a W anode X-ray tube on a highly-oriented mosaic crystal.
