Which component of an indirect capture flat-panel detector converts incident x-ray photons into visible light photons?

Explanation:
In indirect capture detectors, x-ray energy is first turned into visible light by the scintillation layer. This material absorbs x-rays and re-emits photons in the visible spectrum, using compounds like CsI(Tl) or gadolinium oxysulfide to balance light yield and sharpness. The visible light image is then converted to an electrical signal by the photodiode array, while the thin-film transistor network handles readout. The scintillation layer is the part that performs the initial x-ray to light conversion, which is why it’s the correct choice.
