Low-dose spectral CT reconstruction using image gradient ℓ(0)–norm and tensor dictionary
Spectral computed tomography (CT) has a great superiority in lesion detection, tissue characterization and material decomposition. To further extend its potential clinical applications, in this work, we propose an improved tensor dictionary learning method for low-dose spectral CT reconstruction wit...
