Journal ArticleDOI
Normalized metal artifact reduction (NMAR) in computed tomography
TL;DR: In this paper, a generalized normalization technique for MAR is proposed, which can reduce metal artifacts to a minimum, even close to metal regions, even for patients with dental fillings, which cause most severe artifacts.
Journal ArticleDOI
Noninvasive coronary angiography by retrospectively ECG-gated multislice spiral CT.

TL;DR: This investigation investigated the applicability and image quality of contrast-enhanced coronary artery visualization by multislice spiral CT using retrospective ECG gating to determine the visualized length of the coronary arteries, the contrast-to-noise ratio, and the correlation of...
Journal ArticleDOI
Generalized multi-dimensional adaptive filtering for conventional and spiral single-slice, multi-slice, and cone-beam CT.
TL;DR: A generalized multi-dimensional adaptive filtering approach that applies nonlinear filters in up to three dimensions in the raw data domain that has a great potential to reduce metal artifacts, e.g., in the hip region.
Journal ArticleDOI
Improved total variation-based CT image reconstruction applied to clinical data
TL;DR: A new method to adapt the step-size adaption of the ASD-POCS algorithm to solve the problems of angular undersampling, data lost due to metal implants, limited view angle tomography and interior tomography.
Journal ArticleDOI
ECG-correlated image reconstruction from subsecond multi-slice spiral CT scans of the heart.
TL;DR: In this article, the authors developed and validated dedicated cardiac reconstruction algorithms for imaging the heart with subsecond multi-slice spiral CT utilizing electrocardiogram (ECG) information.
