Evaluation of a metal artifact reduction algorithm for flat panel detector CT-angiography in patients after surgical or endovascular treatment of intracranial aneurysms

Autor: Pjontek, R, Önenköprülü, B, Hänsel, N, Kyriakou, Y, Scholz, B, Schubert, G, Nikoubashman, O, Othman, A, Wiesmann, M, Brockmann, MA

Publikováno v: 66. Jahrestagung der Deutschen Gesellschaft für Neurochirurgie (DGNC); 20150607-20150610; Karlsruhe; DOCP 140 /20150602/

Objective: Flat panel detector angiographic computed tomography with intravenous contrast agent injection (ivACT) allows high-resolution imaging of cerebro-vascular structures. Metal artifacts caused by metallic implants like clips or coils lead to r

Accelerating ring artifact correction for flat-detector CT using the CUDA framework

Autor: Willi A. Kalender, D. Prell, Kyriakou Y, W. Chen

Publikováno v: SPIE Proceedings.

Ring artifacts often appear in flat-detector CT because of imperfect or defect detector elements or calibration. In high-spatial resolution CT images reducing such artifacts becomes a necessity. In this paper, we used the post-processing ring correct
