The Wilcoxon signed rank test was used for statistical analysis to compare the qualitative parameters (diagnostic acceptability, image noise, streak artefact, spatial resolution and contrast resolution), and normally distributed quantitative indices were compared using a paired t-test.
The sample emission was dispersed by a spectrograph (0.35 m focal length) and detected by a streak camera (temporal resolution of 17 ps).
There was no significant difference in streak artefact or contrast resolution scores between ASiR-70 and ASiR-90; therefore, the images reconstructed at a slice thickness of 5 mm with 70%% ASIR were chosen as the LD-CT data set with optimal image quality and were chosen for the clinical analysis of stone conspicuity (Fig. 2).
At regular intervals following transformation (2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, and 36 hours), one tube of cells not yet nearing saturation was withdrawn, and a small aliquot was streaked to single cell resolution on dextrose growth agar.
For example, the 5-inch Streak display only has a resolution of 480×800 while the Note boasts a 1280×800 resolution on a 5.3-inch HD Super AMOLED screen.
Whereas in (a) timing information is mapped onto energy, here it is mapped to the spatial domain like in a classical streak camera, offering a temporal resolution down to 10 as (see section Simulations).
The time scale of the energy deposition by the laser pulse, ~150 fs is much shorter than the time resolution of the streak camera and the time scale of electron – ion equilibration.
Conventional CT technology provides accurate reconstructions of the alveolar bone but not the teeth due to limited spatial resolution and strong streak artifacts caused by metallic dental restorations and orthodontic brackets when present.
Guidance is provided for optimizing a femtosecond streak camera to obtain higher temporal resolution.
Time traces of amplified spontaneous emission (ASE) of the sample were characterized with a streak camera system with a temporal resolution of about 20 ps.
