Of note, image acquisition was performed in the axial plane, because, in our experience, direct coronal imaging tends to suffer from severe image distortion because of the requirement of a larger field of view.
Furthermore, binning CT projection data acquired over several cycles into a single cycle leads to severe image artifacts.
Snow asked that the portrait should feature him without his colourful ties, so the artist complied, painting quite a severe image of the newscaster, open necked shirt just visible.
Let us examine an STM tip separation that caused severe image artifacts, bu = 0.77 = π/4 − ε.
Head motion can lead to severe image degradation and result in false-positive activation and is usually worse in patients than in healthy subjects.
However, the use of these parameters was considered not feasible for reuse of baseline VOIs due to (severe) image artefacts that were observed in the registered images.
It was been pointed out that, although beam deceleration in SBEM improves the contrast and resolution of the BSE image, it also leads to severe image artifacts whose cause is unclear [9].
The novel image processing techniques used in the tracking system successfully address the four major problems associated with tracking cells in vivo: background movement, severe image noise and clutter, cell deformation and contrast change, and occlusion of the target cell by other structures.
However susceptibility-based signal loss and severe image distortion caused by air tissue interfaces or other sources of local field heterogeneity are much more severe at higher fields, thus reducing SWI's usefulness in the evaluation of the posterior fossa and skull base.
As a result, the continent continues to suffer from a severe image deficit, one which goes both ways.
