Optimal weighting strategies for maximizing contrast‐to‐noise ratio in photon counting CT images
Medical PhysicsAbstractBackgroundPhoton counting detectors (PCDs) with energy discrimination capabilities have the potential to generate grayscale CT images with improved contrast‐to‐noise ratio (CNR) through optimal weighting of their spectral measurements.PurposeThis study evaluates the CNR performance of grayscale CT projections and images generated from spectral ...
