Abstract
An apparatus for determining the quality of X-ray tubes by analyzing filmed images of the focal spots produced by the tubes. In an exemplary embodiment of the apparatus, a slide scanner receives a filmed focal spot from an X-ray tube and scans it to produce a digital version of the focal spot. The digital focal spot is then analyzed by a personal computer to determine parameters relating to the focal spot such as its background and peak optical density, line spread function, modulation transfer function, skew, and loading. These parameters are then compared to parameter standards to determine whether the X-ray tube should be accepted or rejected under current quality standards.
