Cesium iodide is abbreviated as CSI. Inorganic halides including CSI (TL) are widely used as scintillation media for high-energy particles and ionizing radiation detectors. The vacuum deposited CSI (TL) film was first used for X-ray imaging in photoelectric converter. In advanced digital X-ray imaging, CSI (TL) scintillator film is widely used in X-ray imaging because of its high scintillation efficiency, high spatial resolution and good matching of silicon-based readout array with spectral sensitivity.
