Denoising dual-energy abdominal CT of obese patients

The purpose of this study was to evaluate a novel algorithm for noise reduction in obese patients for dual-source dual-energy (DE) CT abdominal imaging. We demonstrated that multi-channel denoising methods (RSKR, multi-energy (ME)-NLM) could reduce image noise and improve both objective image quality metrics like contrast-to-noise ratio (CNR) and subjective metrics like reader satisfaction.Fides R.

Spectral CT imaging using GaAs and CdTe photon counting detectors

In this study, we compared the performance of PC micro-CT imaging when using two types of PCDs. We have also demonstrated the ability of PCDs to separate a wide range of K-edge materials.
