The authors report the results obtained with a novel readout system for scintillating fibers and x-ray imaging based on the combination of a silicon pixel detector and one stage of light amplification using a 2nd generation image intensifier. The pixel detector is a hybrid assembly of a high resistivity silicon detector bump-bonded to a CMOS binary readout chip and can be read out a speed of 15 MHz. Each pixel element measures 75{micro}m x 500{micro}m. Scintillating fiber ribbons and scintillating crystals are coupled to the detector array using one stage of light amplification provided by a micro-channel plate (MCP) image intensifier with fiberoptic faceplates. They have used the system to image electron tracks in a bundle /of scintillating fiber ribbons. Further they have shown how the system can be used for imaging 122 keV x-rays such as those used in nuclear medicine. The system provides the possibility of single photon counting, high spatial resolution and Compton rejection.
