Paper Abstract

In attempting to specify the performance of an x-ray tube focal spot, a number of factors must be taken into consideration which influence the spatial and intensity distribution of the focal spot: Tube potential, tube current, off-focus radiation, and off-axis variations. In addition, a knowledge of the tube loading capabilities is necessary to adequately predict the focal spot's role in the total imaging process. This paper presents techniques that were developed to investigate some of these factors and some typical results of work to date.
