Article Snippet: Funding information NIH, Grant/Award Numbers: R01EB001838, R01HL155293, P41EB028744 Abstract Background: High tube current generates a high flux of x-rays to photon counting detectors (PCDs) that can potentially result in the piling up of pulses formed by concurrent photons, which can cause count loss and energy resolution degradation.. Purpose: To evaluate the performance of clinical photon-counting CT (PCCT) systems in high flux, potentially influenced by pulse pileup effects, in terms of task-generic image quality metrics.. Methods: A clinical phantom was scanned on a commercial PCCT scanner (NAEOTOM Alpha, Siemens) at 120 kV under fourteen different tube current levels (40–1000 mA) with a rotation time of 0.25 s and a pitch of 1.The dose levels corresponded to CTDIvol (32 cm phantom) of 0.79–19.8 mGy.CT sinograms were reconstructed using QIR-off mode (noniterative reconstruction algorithm), Br44 kernel, and a voxel size of 0.4102 × 0.4102 × 3 mm3. imQuest, an opensource MATLAB-based software package was used to calculate noise power spectrum (NPS), task transfer function (TTF), contrast-to-noise ratio (CNR),and CT number according to AAPM Task Group 233 metrology. |
