Abstract
X-ray flat panel detector (FPD) is key device allowing X-ray diagnostic systems to support more sophisticated medical care. FPD is solid-state device which provides high quality diagnosis image through the conversion of X-ray images of the human body into digital signals.
Features of the FPD are that high quality image can be outputted in real time and shape is compact. These features enable improved diagnostic capabilities, and reduce the burden on the patient.
High X-ray detective quantum efficiency (DQE) of FPD is required in order to reduce radiation dose, and high image quality is required in order to detect of small diseases. A fine cesium iodide (CsI) scintillator crystal formation is applied for achieving these performance requirements.
In this paper, mainly the techniques of the FPD which made by Toshiba Electron Tubes & Devices Co., Ltd. will be described.
