Sentence examples for edge artefacts from inspiring English sources

This could be attributed to edge artefacts (Gibbs artefacts) that occur when PSF is used in iterative reconstruction algorithms, as previously shown by Nakamura et al. [30].

It can be seen that there appears to be a particular size of object where an overestimation with HD and UHD is particularly prominent with no or minimal levels of post-filtering, which, in part, may be due to overlapping Gibbs edge artefacts.

Voxels which displayed missing signal, e.g. due to edge artefacts, were excluded from analysis.

Real time compound spatial imaging reduces edge artefacts, shadowing and speckle, making lesion borders and internal echotexture more readily assessable.

Subjective image quality was assessed by using the following criteria: edge sharpness, artefacts, amount of noise, tissue contrast, and reformat quality.

The TF amplitude of each event and condition was calculated before or after 1 s of each event epoch to minimize the edge artefact of the low-frequency wavelets, and averaged across single trials.

In addition to acquiring high-quality images, the images were cropped to remove edges artefacts present (Fig. 2b).

These edge effect artefacts could be avoided, or at least minimised, by adopting a "crown-distributed" carbon density approach in the LiDAR analysis stage.

It uses photometric weighting to identify significant discontinuities (representing edges), minimizing artefacts and noise.

a Ultrasound showing an oval-shaped mass with mixed echogenicity, globally isoechoic, with an edge effect artefact.

An acoustic shadow, a mixture of acoustic shadow and attenuation, or an edge effect artefact may be observed (Fig. 7a and b).
