Brightness is defined as the flux per unit of solid angle of the radiation cone. It takes thus the beam divergence into account. The unit is p.p.s. [math]\textstyle{ \times }[/math]mra2. Brightness is an appropriate parameter to use when comparing two X-ray sources with identical focal spot size, as the definition does not contain a unit area.
