Idea of thin-film beam splitters for two-colour beamlines

The idea to split soft X-ray and hard X-ray beams on the same axis into different directions is presented. A thin-film beam splitter can serve this purpose. Performances of thin-film beam splitters made of carbon and aluminium were examined. The idea of thin-film beam splitters expands possibilities in the design of two-colour beamlines.

Therefore, it is essential to use reliable dosimeters in the radiation dosimetry course. One of these dosimeters is an extrapolation chamber. It is a plane-parallel ion chamber (PPIC), which its sensitive volume can be varied. In this paper, the performance of an extrapolation chamber has been evaluated in 60–200 kVp X-rays. It was sub...

This study was conducted to evaluate the clinical effectiveness treatment effects of a simple buccal technique for maxillary molar distalization using direct buccal skeletal anchorage.Materials and methodsAfter sample size calculation, fourteen female patients with bilateral Class II molar relationship (age 11–14 years) were selected from the clinic of the Department of Orthodontics, Faculty of Dentistry, Mansoura University, Egypt. After the application of the eligibility criteria, only eleven patients remained to final evaluation. The criteria included: erupted second maxillary molars, mild to moderate maxillary cr...

AbstractDosimetry for kilovoltage X-ray units requires a careful choice of equipment due a typically high energy dependence of standard detectors. The use of optically stimulated luminescence detectors (OSLDs) for in-vivo dosimetry and the measurement of relative output factors is investigated in this study. Supralinearity and the suitability of OSLDs for relative dose measurements are determined for the Landauer nanoDot OSLD system (Landauer, Inc., Greenwood, IL). OSLDs were found to exhibit supralinearity for therapeutic doses in kV X-rays, with the effect more pronounced in lower energy beams. Relative lead cutout facto...
