Abstract

An X-ray detector of conventional design having photodiodes and scintillator material arranged thereon is able, given a suitable read-out frequency matching a low dose to which the flat-panel X-ray detector is subjected, to obtain images during each read-out operation, from which images the energy of individual X-ray quanta can be derived. An item of X-ray-spectrum information about pixels in a grid pattern can be obtained thereby.
