Abstract

The measured equivalent x-ray tube focal spot size can be evaluated by either pinhole camera images or star resolution test object measurements. By a rather simple calculation using the measured equivalent focal spot size and the focal spot-to-screen film and object-to-screen film distances, the geometric resolution limit can be determined. This resolution limit can be used to indicate the needed focal spot size and focal spot-to-object distance for each diagnostic procedure to utilize properly the resolution capability of the screen-film system. This calculation is also important when screen-film systems of different reso-lution are considered for a particular diagnostic procedure. Data are presented for upper gastrointestinal, chest, breast, abdominal and extremity radiography.
