Thermal X-ray composites as an effect of projection
A new possibility to explain the nature of thermal X-ray composites (TXCs), i.e. a class of supernova remnants (SNRs) with a thermal X-ray centrallyfilled morphology within a radio shell, as a projection effect of the 2or 3-dimensional shell-like SNR evolved in a nonuniform medium with scale-height ≤ 10 pc is proposed. Both X-ray and radio morphologies, as well as the basic theoretical features...
متن کاملSoft-x-ray projection lithography
Soft-x-ray projection imaging is demonstrated by the use of 14-nm radiation from a laser plasma source and a single-surface multilayer-coated ellipsoidal condenser. Aberrations in the condenser and the Schwarzschild imaging objective are characterized and correlated with imaging performance. A new Schwarzschild housing, designed for improved alignment stability, is described.
متن کاملreproducible x-ray projection geometry in endodontic practice
introduction: clinical application of radiography in endodontic practice is affected by reproducibility in the orientation of the x-ray source, image receptor and object. the inability of dentists to locate intra oral films or sensors in appropriate positions in different cases can cause complications in the performance of endodontic therapy. commercially available film holder (endoray) and con...
متن کاملFootprint as an alternative to X-ray in hallux valgus angle measurement
Background: X- ray images provide accurate and reliable data in different foot pathologies. However, the accompanied complications will limit its use for epidemiological studies and research purposes, especially in children. Therefore, simple, accessible, and cost- effective methods such as footprint, with a good correlation with x-ray images, are needed to help diagnose different foot pa...
