TL;DR: Comparing DECT with future MECT, the authors found noticeable material image quality improvements for an ideal photon counting detector; however, a realistic detector model with multiple energy bins predicts a performance on the level of dual source DECT at 100 kV/Sn 140 kV.

TL;DR: Pseudo-monochromatic imaging is able to reduce beam hardening, scatter, and metal artifacts in some cases but it cannot remove them, and raw data-based dual energy decomposition methods should be preferred, in particular, because the CNR penalty is almost negligible.

TL;DR: An increment matrix approach describing the signal statistics of energy-selective photon counting detectors including spatial-spectral correlations between energy bins of neighboring detector pixels is introduced and evaluated and found to be of weak nature.

TL;DR: In this paper , the authors compared the image quality of contrast-enhanced abdominal 1st-generation Photon-Counting Detector CT (PCD-CT) to a 2nd-generation Dual-Source Dual-Energy-Integrating-Detector (DSCT) in obese patients.

TL;DR: In this article, the authors proposed an image-based method that determines optimal bin image weighting factors for material decomposition with respect to minimal material image noise, and showed that a perfect photon counting detector with four bins outperforms the dual energy CT technique by a noise reduction of 22% in the water image and 43% in an iodine image.
