Accessible Web design is not very complicated to accomplish, but several aspects have to be considered. By using an example page, the process of transforming a not accessible page into an accessible one is demonstrated. This includes the evaluation of the current Web site and several steps of redesign like the overall design, textual equivalents, style(More)
Soft x-ray lithography is a promising micro-nano fabrication process for patterning ultra-precise, low and high aspect ratio micro-and nanostructures [1-5]. A new negative-tone, epoxy-based x-ray resist, mr-X, which offers comparable contrast to PMMA (> 3) at a factor of 20x higher sensitivity, is a promising candidate for this approach [6]. Using a 1 µm(More)
PURPOSE Verifying an algorithm to reconstruct relative initial photon fluence for clinical use. Clinical EPID and CT images were acquired to reconstruct an external photon radiation treatment field. The reconstructed initial photon fluence could be used to verify the treatment or calculate the applied dose to the patient. METHODS The acquired EPID images(More)
