摘要
目的:研究探讨及构建一种体积小、重量轻、易于携带且方便使用的低剂量数字X射线成像仪。方法:采用二极管线性阵列(LDA)探测器和成像系统(CMOS互补金属氧化物半导体/晶体管)传感器相结合的组合方式进行构建。结果:可一步完成X射线光电转换、数字采集的过程,实现直接数字化成像。将数字X射线成像仪所获取的数字成像信号进行无线传输,通过无线传输,将数据传输到服务器上以便医师进行分析。结论:构架出一个对X射线成像设备进行数字成像并进行无线数据传输的系统装置,并具有便携、易用、军民两用的特点。
Objective： To research and construct a digital X ray imaging apparatus with small volume, light weight, easy portability and low dose. Methods： The digital X ray imaging apparatus was constructed by using the linear array detector and imaging system sensor in combination. Results： This mode can be further used to complete X ray photoelectric conversion, digital acquisition and realized direct digital imaging. This digital X ray imaging apparatus acquired digital imaging signal, transmitted the data to the server through wireless transmission, then the data were analyzed conveniently by physicians. Conclusion： This device of digital imaging and wireless transmission has been constructed for the X ray advantages of convenience, portability and dual-use characteristics.
