Abstract

Off-focus x-radiation is an undesirable feature of many types of x-ray tubes, particularly with respect to rotating-anode x-ray tubes as used in medical diagnostic applications. This radiation tends to enlarge the source of x-rays, consequently, degrading the quality of the image produced in the detecting system. A thorough study of the production mechanisms and the control of off-focus x-radiation would be of interest to those engaged in x-ray radiological applications. Based on measurements of x-ray intensity and spectral distribution of off-focus radiation, the predominate mechanisms that create off-focus radiation were determined for a rotating-anode x-ray tube .
