Abstract

The x-ray tube focal spot intensity distribution is a continuum of numbers describing the source strength as seen in some plane under some set of specified conditions. Focal spot "size" is one number which attempts to communicate something meaningful about the continuum of numbers, e.g., perceptible outside dimensions on a pin-hole radiograph of the focal spot, disappearance frequency for a specified magnification, size of uniform distribution giving the same disappearance frequency, etc. A user might like to know the "size" of a focal spot so as to rank it against others, and to predict its effect on an overall imaging procedure.
