By using the information extracted with the help of the reference targets, a human operator is able to correct any inaccuracies of the scanning procedure on-the-fly.
Found in Wyoming, this new skeleton from the Late Cretaceous Period is a product of traditional bone replication by molding and casting, as well as three-dimensional laser scanning and prototyping that fixes many inaccuracies in the original mount.
First, non-uniform motion of the probe during lateral manual scanning will cause image distortion and inaccuracy.
The apparatus allows to perform the scanning of a generic surface with medium accuracy (inaccuracy <±50 μm).
Figure 4(b) shows the untracked reconstruction, in which the artifacts caused by variations in scanning speed and orientation can be clearly observed as inaccuracies in the positions, shapes, and sizes of the grooves.
It surmounts the subjectivity, inaccuracy, and uncertainty analysis based on traditional BCCH frequency scanning measuring being equivalent to TCH frequency measuring.
Flügge et al. [32] found that intraoral scanning was less precise than extraoral model scanning, indicating that the intraoral conditions contribute to the inaccuracy of scans.
Some software automatically identifies the end of the first pass; however, for protocols where perfusion scans last longer than the end of the first pass, such an automatic identification could lead to inaccuracies and it is necessary to manually identify the first pass.
Since all scans have the same provenience and were taken in the same time interval, it seems most likely that these inaccuracies are simply glitches in the image metadata.
Body length was determined by measuring nasal-to-anal distance to the nearest 0.1 mm using a caliper when mice were anesthetized and immediately after DEXA scan, in order to avoid inaccuracy from movement and to confirm with X-ray images the precise positioning of mice.
