When detector frames are read out in the presence of intense X-ray illumination, an offset is imposed on the pixel output. The offset is a strong function of the dose rate received by the underlying CMOS ASIC during readout. This plot suggests a power law relationship between offset and dose rate (Gy s−1) of the CMOS ASIC. If the CMOS ASIC is not illuminated during readout (e.g. the source is shuttered), no offset is observed. |
