Description
技术领域technical field

背景技术Background technique
自1995年推出第一台平板探测器(flatpaneldetector)设备以来，随着近年平板探测器技术取得飞跃性的发展，众生产商和研究人员已经将平板探测器数字X射线探测器从实验室带到了临床使用中，由于平板探测器具有的高灵敏性，宽动态范围及数字化图像的低畸变等优势，医院用户正在不断增多，平板技术也逐渐走向普及，平板数字X射线成像技术成为引发X射线诊断影像革命的中坚力量。平板图像传感器，特别是大尺寸图像传感器，面积通常数十厘米，数百万至千万像素。通常应用于医疗辐射成像、工业探伤、安检等领域。Since the launch of the first flat panel detector (flat panel detector) equipment in 1995, with the rapid development of flat panel detector technology in recent years, many manufacturers and researchers have brought flat panel detector digital X-ray detectors from the laboratory to the In clinical use, due to the advantages of high sensitivity, wide dynamic range and low distortion of digital images of flat-panel detectors, hospital users are increasing, and flat-panel technology is gradually becoming popular. The backbone of the imaging revolution. Flat-panel image sensors, especially large-scale image sensors, usually have an area of tens of centimeters and millions to tens of millions of pixels. Usually used in medical radiation imaging, industrial flaw detection, security inspection and other fields.
在平板探测器的研发和生产过程中，平板探测技术可分为直接和间接两类。近年来平板探测器技术取得了飞跃性的发展，由于直接转换式的平板探测器研发较为复杂，早起实验室研究不能方便的用于商业化生产，而间接转换式的平板探测器由研发到商业规模化生产较为方便易行，所以早期的平板探测器新产品中大多数采用间接转换方式，间接转换式的平板探测器结构主要是由闪烁材料或荧光材料层加具有光电接收二极管作用的非晶硅层加TFT阵列构成。其原理为闪烁体或荧光材料层经X射线曝光后，将X射线光子转换为可见光，而后由具有光电接收二极管作用的非晶硅层变为图像电信号，最后获得数字图像。In the development and production process of flat-panel detectors, flat-panel detection technology can be divided into two categories: direct and indirect. In recent years, flat panel detector technology has made great progress. Due to the complexity of the research and development of direct conversion flat panel detectors, early laboratory research cannot be conveniently used in commercial production, while indirect conversion flat panel detectors have been developed from R&D to commercial Large-scale production is more convenient and easy, so most of the early new flat panel detector products adopt the indirect conversion method. The structure of the indirect conversion flat panel detector is mainly composed of scintillation material or fluorescent material layer plus an amorphous Silicon layer plus TFT array. The principle is that after the scintillator or fluorescent material layer is exposed to X-rays, the X-ray photons are converted into visible light, and then the amorphous silicon layer with the photodiode function is converted into an image electrical signal, and finally a digital image is obtained.
