IC was calculated after the experimental determination of the noise equivalent quanta (NEQ) under the IEC 62220-1-1:2015 standard’s RQA-5 beam quality. The detector response function was linear for the X-ray exposure range under investigation. At 70 kVp, under the RQA-5 irradiation, the IC value was 2119 bits/mm 2 . The information content of the particular detector was found comparable with other CMOS sensor / scintillating screens combinations, under similar X-ray exposure conditions. © 2021 The Authors.
