Shown above is the X-ray sensor DQE as a function of spatial frequency, for a range of X-ray
doses from 50 to 600 uGy. The curves indicate that there is no significant change in DQE
performance going from 50 uGy to 600 uGy. This implies that the sensor operates quantum-
limited over that dose range, indicating that all photons are being used effectively and that
noise does not degrade performance at low doses. The curve also indicates that device can
resolve detail down to 20 lp/mm (over all doses). This means that the X-ray sensor exhibits no
reduction in resolution over the input dose range from 50 to 600 uGy.
