CT coronary angiography: image quality with sinogram-affirmed iterative reconstruction compared with filtered back-projection
R Wang, UJ Schoepf, R Wu, KP Gibbs, W Yu, M Li… - Clinical radiology, 2013 - Elsevier
AIM: To investigate image quality and potential for radiation dose reduction using sinogram-
affirmed iterative reconstruction (SAFIRE) at computed tomography (CT) coronary
angiography (CTCA) compared with filtered back-projection (FBP) reconstruction.
MATERIALS AND METHODS: A water phantom and 49 consecutive patients were scanned
using a retrospectively electrocardiography (ECG)-gated CTCA protocol on a dual-source
CT system. Image reconstructions were performed with both conventional FBP and SAFIRE …
