This enables lower radiation dose and higher resolution scans. Metal artifacts can also be reduced using iterative reconstruction, resulting in a more accurate diagnosis. Dual- and multi-energy (photon counting) CT can reduce beam hardening and provide better tissue contrast. Methods for reducing ...
In an idealized situation, with high radiation dose, and thus high photon counts, monochromatic x-rays, infinite detector resolution, perfect detectors, no motion and no scatter, CT images would be a perfect reflection of reality. If any of those conditions are not met, then artifacts will ...

As most of these significant differences had disappeared after 12 months, it is obvious that these findings reflect acute radiation damage to the lens epithelial cells and an ionising effect on the proteins of the lens nucleus. Long term studies will have to be carried out to demonstrate whether...

To verify this, we measured the singlet oxygen generation (type-II photochemistry) of sunitinib by direct detection of its phosphorescence at 1270 nm, after pulsed excitation with 355 nm laser radiation in acetonitrile and DMSO (Sigma-Aldrich, Buchs, Switzerland). The quantum yield of singlet ...
With these calcium imbalances, we therefore examined microstructural changes of long bones of the hind limbs. Using the synchrotron radiation x-ray tomographic microscopy, we showed that trabecular structure of tibia and femur of HSD displayed a marked increase in porosity. Consistently, the volumetric...
oxidation and radiation defence. Research concerning acute or chronic toxicity of copper due to its deficiency or excess is growing rapidly and interest in the subject is pervasive [4,5,6,7,8,9,10,11,12]. Nevertheless, the pertinent redox status-dependent chelation [13,14,15,16,17,18,19...
