Corrections for nonuniform x‐ray intensity distributions have been computed for the dimension perpendicular to the anode–cathode axis of x‐ray‐tube focal spots. These correction factors were developed from comparison of OTFs for focal spots with uniform intensity distributions to those for focal spots with symmetric double‐peaked intensity distributions.
