Artifacts in Plasma Volume Changes due to Hematology Analyzer-Derived Hematocrit
PLASMAOSMOLALITY PACKEDCELLVOLUME ERYTHROCYTEVOLUME BLOODVOLUME DILLANDCOSTILL
2017/5/17
This investigation quantified the effect of changes in plasma osmolality on the measurement of hematocrit (Hct) and the implications for the subsequent use of these data to calculate changes in plasma...
Metal artifacts in MRI from non-magnetic dental alloy and its FEM analysis
MRI Metal artifacts of MR image FEM electromagnetic field analysis

Reduction of CPR artifacts in the ventricular fibrillation ECG by coherent line removal
CPR artifacts the ventricular fibrillation ECG coherent line removal
2010/2/25
The localized coherent line removal algorithm reduces CPR-artifacts in VF-ECG, but does not eliminate them. Our SNR-improvements are in the same range as offered by multichannel methods of Rheinberger...
Interpolation Artifacts in Sub-Pixel Image Registration
Image registration interpolation artifacts mutual information
2009/12/23
We consider the problem of registering(aligning) two images to sub-pixel accuracy by optimization
of objective functions constructed from the images' intensity values.We show that some widely use
in...

Analysis of Cone-Beam Artifacts in off-Centered Circular CT for Four Reconstruction Methods
Cone-Beam Artifacts CT
2009/9/8
Cone-beam (CB) acquisition is increasingly used for truly three-dimensional X-ray computerized tomography (CT). However, tomographic reconstruction from data collected along a circular trajectory with...
Suppression of MRI Truncation Artifacts Using Total Variation Constrained Data Extrapolation
Variation Constrained Data Extrapolation MRI
2009/9/4
The finite sampling of k-space in MRI causes spurious image artifacts, known as Gibbs ringing, which result from signal truncation at the border of k-space. The effect is especially visible for acquis...
Artifacts Due to Movement in Rotational Panoramic Radiography
Movement Rotational Panoramic Radiography
2009/3/2
Artifacts caused by movement in rotational panoramic radiology and in conventional radiography are very different. Artifacts originating from disturbed movement of the x-ray source as well as from m...
