线性二极管阵列用于扫描辐射场以进行脉冲高能X射线成像。每个光束脉冲的每个二极管的信号约为50二二二二二二二二二二二二极管，开放田图像的信号与噪声比为119。辐射。与标准放射疗法膜相比，所得的电子图像的质量优越。检测器系统的简单性证明了构建电子门户成像系统的可行性。
A linear diode array was used to scan a radiation field for pulsed high energy x-ray imaging. With a signal of about 50 pico-coulombs of charge from each diode for each beam pulse, the signal to noise ratio for an image of an open field was 119. An image of a porcine femur in a wax phantom was obtained by scanning the transmitted radiation. The resultant electronic image was superior in quality when compared to the standard radiotherapy port film. The simplicity of the detector system has demonstrated the feasibility of constructing an electronic portal imaging system for clinical use.
