Lubberts effect
Encyclopedia
Lubberts effect refers to the non-uniform response of an imaging system
to x-ray
s that are absorbed at different depths within the input phosphor
. It indicates an input phosphor depth-dependent response of the imaging system.

to x-ray
X-ray
X-radiation is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 120 eV to 120 keV. They are shorter in wavelength than UV rays and longer than gamma...

Phosphor
A phosphor, most generally, is a substance that exhibits the phenomenon of luminescence. Somewhat confusingly, this includes both phosphorescent materials, which show a slow decay in brightness , and fluorescent materials, where the emission decay takes place over tens of nanoseconds...
. It indicates an input phosphor depth-dependent response of the imaging system.
