Focal Spot Test Patterns
With the aid of a star test (or sector-star test) exposure, the size and shape of tube assembly focal spots can be determined in a very simple manner. This method is less complicated than the pinhole or slit
camera process and assuming an approximately ideal intensity distribution in the focal spot, it is in many cases fully adequate.
