Iterative reconstruction for CT perfusion with a prior-image induced hybrid nonlocal means regularization: Phantom studies
PURPOSE: In computed tomography perfusion (CTP) imaging, an initial phase CT acquired with a high-dose protocol can be used to improve the image quality of later phase CT acquired with a low-dose protocol. For dynamic regions, signals in the later low-dose CT may not be completely recovered if the i...
