Paper Abstract

A PACS terminal contains a film digitizer which reads radiographic images digitally. Aliasing is often generated when the film digitizer reads images acquired on film using an antiscatter grid. Aliasing interferes with CRT diagnosis and therefore must be reduced. This paper clarifies the mechanism by which aliasing is generated and described how it can be reduced to a level acceptable for CRT diagnosis.
