Abstract

A medical imaging member having a three layer structure which inhibits the formation of crystallites and reduces the occurrence of powder deficient spot print artifacts is disclosed. A conventional 0.3% Arsenic-Selenium (As-Se) alloy is an X-ray sensitive material that may be vacuum evaporated and deposited on an aluminum substrate to form an imaging member. In the evaporation process, this alloy is known to fractionate producing selenium rich species early on and arsenic rich species near the end of the evaporation process.
