从硅微带检测器耦合到RX64 ASIC的结果。该系统能够在数字X射线成像中进行单光子计数，可预见应用于双能量乳腺X射线摄影和血管造影。该探测系统的主要特点是低噪声（阈值可低至104keV）、良好的空间分辨率（100 μm ×300 μm）和良好的计数能力（每通道计数可达100万次，最大计数率约为200kHz）。系统的能量分辨率，获得与几个荧光X射线线，进行了说明。
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.
