We assembled an imaging system in a black lead box. The x-ray source used in the system was M237 (50 kV, Newton Scientific) with Au target. The Cs5Cu3Cl6I2 film was placed on a reflector (CCM1-G01, Thorlabs), and the scintillation light was deflected to a CMOS camera (C13440, Hamamatsu) with pixel size of 6.5 μm by 6.5 μm. For the demonstration of chip pipelining inspection, a chip was fixed to a scanning stage (PSA200-11-X, Zolix) at a step rate of 4.5 mm s−1. The camera was set at automatic acquisition mode. For the angiography simulation, a processing approach typical of digital subtraction angiography was applied. A “mask image” was captured before the injection of the contrast agent. This mask image was then subtracted from the subsequent image taken after contrast injection, yielding a clear angiographic image. The pixel values of scintillation photon noise and the camera’s electronic noise were calculated as 6.4 (fig. S26).
DQE was calculated with MIQuaELa software and measured following the guidance of the international standard IEC62372. The noise power spectrum (NPS; fig. S27) and MTF were measured with RQA3 beam, which was produced form a tube (Leo, Varex Imaging) voltage of 50 kV. The detector responses were measured under several different doses to obtain signal transfer property. The absorption dose of 2.5 μGyair was used to measure the NPS of the detector.
