Abstract

Point spread functions for rotational panoramic radiography were determined experimentally. The results were compared with theoretically functions calculated from known system parameters. There was a satisfactory agreement between theoretically and experimentally obtained data. It is concluded that theoretically calculated point spread functions and their blurring effects in panoramic radiography give reliable results.
