XRI's technology is characterized by a modular design, providing size flexibility and reducing costs, photon-counting electronics (*), improving image quality, and the possibility to use different semiconductor materials depending on the field of application, minimizing the radiation dose.
	Modularity introduces the need for scanning but this does not imply a slow image acquisition time. A full size (24 cm x 30 cm) mammography image can be obtained under 1 second. By using independent modules, we are able to employ only those which meet the most strict quality control tests. Also, in the case of malfunction only those modules which are not operational can be unplugged and replaced by new ones.
	Photon counting electronics can distinguish between photons of different energies. Therefore, only photons above a certain threshold are used to form the image eliminating the error introduced by dark currents. This improves significantly the image contrast of the image taken.
	By direct capturing the photon in the semi-conductor material, our technology uses all of the information contained in that photon. Different kinds of semi-conductor materials are now available in the market although this is an emerging sector and many more will become available in the future. Bump-bonding the semi-conductor material to the pixel electronics allows us to employ different kinds of detector material depending on the application. By improving the DQE of the detector in each application we can significantly reduce the radiation dose suffered by the patient.
