In realistic calcified coronary phantoms, deep silicon photon-counting CT reduced percent area stenosis and vessel area measurement errors relative to conventional energy-integrating CT, using micro-CT as ground truth.
In the primary Micro-CT-referenced analysis, dSi-PCCT reduced whole-profile mean absolute error in percent area stenosis from 3.10% with EID-CT to 1.62% (p=0.027)

Evaluation of Silicon-Based Photon-Counting CT for Coronary Stenosis Quantification with Realistic Coronary Artery Phantoms
In realistic calcified coronary phantoms, deep silicon photon-counting CT reduced percent area stenosis and vessel area measurement errors relative to conventional energy-integrating CT, using micro-CT as ground truth.
