1) Using intervals (instead of the raw alpha-cuts) prevents scattering of the support and the core (e.g., a random erroneous rating may split the core and/or the support into two subintervals).
All but two patients received furosemide concurrent with the radiotracer injection to prevent scatter artifact from bladder and kidney activity.
Nanocrystals of <30 nm in size, to prevent scattering in solution, have been prepared, and they can be easily dissolved in organic solvents forming colloidal solutions, without agglomeration.
To prevent scatter from the lungs or liver, a circular ROI with a radius of 21 pixels was chosen, fitting into the apex of the myocardium without covering surrounding lung or liver tissue.
The vanes are structures in the baffle preventing scattering from walls.
In the non-descanned PMT detectors (R6357, Hamamatsu, Shizuoka, Japan), a 700 nm short pass filter (E700SP, Chroma Technology, USA) was used to prevent the scattered IR laser radiation from reaching the detector and a 455 long pass dichroic beam splitter (455 DCXRU, Chroma Technology, USA) was used to separate SHG signal from the MPEF signal.
An (in-column) energy filter with an energy slit of 10 eV prevented inelastically scattered electrons from contributing to the image.
An objective aperture is placed in the back focal plane of this lens; the aperture prevents electrons scattered at high angles from reaching the image plane, thus improving the image contrast.
CoQ10 treatment in the old mice restored normal spindle appearance and prevented chromosomal scattering to a degree indistinguishable from young dams (Fig. 3A).
(C) The optimized pinhole collimator for bremsstrahlung SPECT avoids these scattering paths (e) to prevent wall scattering of high-energy X-rays penetrating through the nose of the gold insert; an empty space (f) is left between the collimator housing and the extreme rays (dot-dash lines) passing through the aperture.
