1. 1. A study of some energy dependent characteristics of X-ray screens used in diagnostic radiology : screen-film sensitivity, MTF and some related factors

   Författare :Mikael Karlsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensifying screens; x-ray screens; fluorescent screens; modulation transfer function; MTF; x-ray screen sensitivity; fluorescent K-radiation sources;

   Sammanfattning : Fluorescent x-ray screens are used in medical x-ray diagnostics to absorb x-ray photons and convert these x-ray photons to visible light. The light distribution from these screens are then registered on photographic film to give an x-ray image. LÄS MER

3. 2. Electrochemically etched pore arrays in silicon for X-ray imaging detectors

   Författare :Xavier Badel; Jan Linnros; Volker Lehmann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Elektrofysik; Electrophysics; Elektrofysik;

   Sammanfattning : Digital devices have now been introduced in many X-ray imaging applications, replacing slowly traditional photographic films. These devices are preferred as they offer real time imaging, easy handling and fast treatment of the images. LÄS MER
