Abstract: Purpose Acquisition of high‐quality x‐ray images using low patient exposures requires detectors with high detective quantum efficiency (DQE). We describe a novel apodized‐aperture pixel (AAP) design that increases high‐frequency modulation transfer function (MTF) and DQE… read more here.

Abstract: BACKGROUND Assessing the performance of spectroscopic x-ray detectors (SXDs) requires measurement of the frequency-dependent detective quantum efficiency (DQE). Analytical expressions of the task-based DQE and task-independent DQE of SXDs have been presented in the literature,… read more here.
