Hybrid Pre-Log and Post-Log Image Reconstruction for Computed Tomography [PDF]
IEEE Transactions on Medical Imaging, 2017 Tomographic image reconstruction for low-dose computed tomography (CT) is increasingly challenging as dose continues to reduce in clinical applications. Pre-log domain methods and post-log domain methods have been proposed individually and each method has its own disadvantage.
