N1 - Funding Information:
We are grateful to B. Pini for help with the assembly of detectors and ASICs, to E. Filoni for the layout of the pitch adapter, and to F. Rotondo for help with cabling. We acknowledge help from L. Fava, P.F. Ottria and D. Panzieri for setting up the X-ray tube in the Physics Laboratory of the Dipartimento di Scienze e Tecnologie Avanzate in Alessandria. This work was supported by the Ministero dell'Università e Ricerca Scientifica e Tecnologica (MURST) of Italy under contract N. COFIN-2000-MM02095297-003. We are grateful to the Istituto Nazionale di Fisica Nucleare (INFN)—Sezione di Torino for financial and logistic support. Two of us (A.E.C.R., A.D.C.) acknowledge the support from the ICTP Programme for training and research in italian laboratories (ICTP-TRIL).

N2 - Results from a silicon microstrip detector coupled to the RX64 ASIC are presented. The system is capable of single photon counting in digital X-ray imaging, with foreseen applications to dual energy mammography and angiography. The main features of the detecting system are low noise (operation with threshold as low as ≈4 keV is possible), good spatial resolution (a pixel of 100 μm×300 μm when oriented edge-on) and good counting rate capability (up to one million counts per channel with a maximum rate of about 200 kHz per channel). The energy resolution of the system, as obtained with several fluorescence X-ray lines, is described.
