In the framework of the realization of dedicated Cone-Beam Breast Computed Tomography (CBBCT) apparatus we report the MTF characterization of our prototype having the best performance in terms of detector pixel size and X ray focal spot than any other systems built or under construction. From our measurement we estimated a value of the longitudinal and transverse resolution of 4-5 lp/mm (at 10% MTF)...
It is well known that a monochromatic X-ray source with an energy optimized for the organ thickness to be imaged could result in a better image quality in transmission radiology. In this paper we present the preliminary investigation for the implementation of this technique in computer tomography (CT) imaging. The detection system is based on a 1mm thick silicon pixel detector bump bonded to a VLSI...
