Bone-induced streak artifact suppression in sparse-view CT image reconstruction

Abstract

BACKGROUND In sparse-view CT imaging, strong streak artifacts may appear around bony structures and they often compromise the image readability. Compressed sensing (CS) or total variation (TV) minimization-based image reconstruction method has reduced the streak artifacts to a great extent, but, sparse-view CT imaging still suffers from residual streak… (More)
