WebCdTe is a direct conversion detector and as such does not need to turn the X-ray photon into a light photon before recording it. This means the position of the conversion can be more accurately recorded and the signal is directly related to the energy of the converted photon. Other radiation detectors use scintillators to convert X-rays to light.
WebJan 28, 2024 · PCDs for x-ray CT are so-called direct-conversion detectors, wherein the x-ray photons are converted directly into an electric signal as opposed to first being converted to visible light.
