We further demonstrate that such apertures can be fabricated from thin-foil materials by milling with a focused ion beam (FIB), and that such apertures are fully compatible with the requirements of imaging out to a resolution of at least 0.34 nm.
During 2010, on average, 2888 brain MRI were performed per radiology department (range 20 24 391 scans; median 1530 scans), only 3% of MR scans were conducted out-of-hours (most performed no MR brain imaging out-of-hours).
Since HiLo imaging rejects out-of-focus-plane scattered light during post-processing, the cameras must have a higher dynamic range than that used in confocal systems, which rejects background light using a physical pinhole.
We have shown that HiLo imaging can reject out-of-focus scatter, and improve resolution of images obtained from a flood AO ophthalmoscope.
In our case, since imaging bore out the hypothesis of DI, we performed a water deprivation test to confirm this diagnosis.
For instance, the bright comet C/1995 O1 (Hale-Bopp) attracted the attention of many observers across the world, and at least three other groups carried out imaging polarimetry of this comet, all giving similar results (i.e., Jockers et al., 1997; Tanga et al., 1997; Furusho et al., 1999).
In endometrial cancer, MRI is used to rule out imaging signs of invasive disease prior to consideration of hormonal treatment.
In most cases, several first and last z-slides contain imaging artefacts (e.g. out-of-focus blur) and have to be discarded.
However, this optical sectioning capability breaks down eventually when imaging much deeper, as the out-of-focus fluorescence gradually overwhelms the in-focal signal in the scattering samples.
The results above demonstrate the benefits of speckle illumination HiLo imaging in selectively rejecting out-of-focus scattered light and improving the resolution and contrast of images obtained from a flood-illumination AO ophthalmoscope.
