Abstract:This paper researched the occasional truncation artifacts during the application of Shimadzu
D-vision digital radiography (DR) photographic system. Through analysis of features of abnormal image
and design features of the DR equipment, the research found out that truncation artifacts were directly
caused by premature movement of the flat panel detector. Based on the finding, the research proposed
a resolution plan in which a flat panel detector delay return control circuit was added. Clinical results
showed that the flat panel detector delay return control circuit integrated with D-vision DR photographic
system could eliminate truncation artifacts caused by flat panel detector motion and improve DR
image quality without decreasing examination efficiency, which allowed the design to be used in the
improvement of related equipments.
