According to Riccioli, "these features are seldom able to be seen, and then only by a telescope of exceptional quality and magnification".
Multiple dose reduction techniques include intermittent fluoroscopy, removal of grid, last image holding, electronic collimation, dose spreading, adjustment of beam quality, image magnification, dose level settings, pulsed fluoroscopy, and appropriate training of fluoroscopy operators.
Magnification quality of the roentgenogram is also very important.
We have worked to improve the image quality at low magnification given the technical constraints as discussed here.
Given the poor quality data (low magnification wholemount in situs which do not recapitulate published caudal expression of Sox2 even in the controls), they should be cautious with the interpretation.
Apple's current iPhone camera uses digital zoom, but this results in far more degradation of quality versus true optical magnification like those found in DSLR telephoto lenses, and compact cameras with traditional zoom lenses.
Other ideal quality criteria include: equal magnification in the horizontal and vertical plane, the same mesiodistal dimension of the right and left molar teeth, uniform density all over the image and no evidence of artefacts.
A Laserdisc version of The Phantom Menace was released in Japan several months before it was available on DVD in the U.S. The Star Wars films were released on Blu-ray Disc on September 16, 2011; The Phantom Menace was restored to improve the picture quality and remove the magnification present on the previous DVD release, restoring approximately 8 percent of the picture to the frame.
This form of detection may depend on the magnification, image quality, as well as sampling density.
Thus, Figure 5 panels M-O are at very low magnification and quality such that the integrity of the AS cells and the DE-cad-GFP adhesion junctions cannot be ascertained.
