A subsequent evaluation of ultrahigh purity aluminum, purchased from a second source, suggests, that reduced grain size can be achieved by the process of annealing. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment.

For Permissions, please email: Our observations of markedly visible nonuniformities in images acquired with high purity aluminum filtration suggest that the uniformity of filter materials should be carefully evaluated and taken into consideration when measuring the DQE. A mobile measurement facility which complies with IEC has been set up to determine the detective quantum efficiency DQE of digital X-ray detector systems.

Exemplary measurements were performed for two similar CR detector systems, a CsI-based indirect detector and an Se-based direct detector. This finding was ultimately attributed to the larger grain size approximately mm of high purity aluminum metal, which is a jec characteristic, particularly in thicknesses greater than 1 mm.
