Regardless of imaging modality, image stabilization is an important consideration during image analysis as motion artifacts decrease the image resolution and the accuracy of image quantification.
Regarding coronary arteries, a score of 1 represented confident depiction (homogenous attenuation; no artifacts decreasing coronary analysis) of the right coronary artery (RCA), left main artery (LMA), left anterior descending artery (LAD), left circumflex artery (LCX), and their side branches.
Presumably, at the higher rates of ventilation, there is relatively less time for exchange with the airways, and the artifact decreases.
However, if the rhythm is continuously analyzed these unreliable analyses can be safely ignored until the amplitude of the artifact decreases.
This process was terminated only if the artifact level decreased to a predefined threshold.
We undertook the current study to determine whether Q fever was still occurring in Maritime Canada (the 3 provinces of New Brunswick, Nova Scotia, and Prince Edward Island in eastern Canada) and whether the decline in cases was real or an artifact of decreased surveillance.
Decreased discretization artifacts and decreased sensitivity to grid alignment are demonstrated, compared to the standard link bounce-back boundary condition.
In many cases, visibility of one set of artifacts is decreased at the expense of increasing the visibility of another set.
However, in regions with ringing artifacts, β decreases to remove the artifacts by adopting the median spatio-temporal result.
The use of dedicated metal artifact reduction algorithm extensively decreased the artifacts at both 120 kV (b) and 140 kV (d).
