Recent breakthroughs in electronic detector technology have allowed digital radiographic images to become competitive with, or superior to, those produced with classical film-screen techniques. A sunmary of these technologies is given in ref. 1. Our group is involved in the research and development of a recently proposed imaging technology (2, 3) based on the kinestatic charge detector (KCD). The modulation transfer function (MTF) of the KCD technique has been discussed in refs. 1 and 4. The low frequency detective quantum efficiency (DQE(O)) of several KCD designs has been modeled and a value of approximately 0.75 is expected for future detectors (1, 5). In this paper, the noise power spectrum (NPS) and the frequency-dependent DC® (DQE(f)) are discussed. Noise contributions from x-ray quanta (random and structured) and data acquisition electronics are considered and preliminary experimental results are given for a recently installed imaging detector. A brief comparison is made of our theoretical and experimental results with published results for film-screen radiography.
