This report describes several different techniques that have been used to determine the peak kilovoltage (kVp) of single- and three-phase diagnostic x-ray units operating in both the radiographic and fluoroscopic mode, from 60 to 110 kVp, using (1) a voltage divider with oxcilloscope display; (2) a voltage divider and special summing amplifier with digital display of the voltage utilizing a multichannel analyzer; (3) a version of the Ardran-Crooks cassette technique; and (4) a Ge(Li) spectrometer method. Each technique presents a distinct advantage: Method (1) enables the waveform to be viewed directly; method (2) is probably the most accurate and reproducible technique; method (3) has the greatest ease of operation; and method (4) provides the ability to visualize the x-ray spectrum.
本报告描述了几种不同的技术，这些技术用于确定在60至110千伏峰值（kVp）范围内，以放射摄影和透视模式运行的单相和三相诊断X射线装置的峰值千伏（kVp），使用的技术包括：（1）带有示波器显示的分压器；（2）带有分压器和特殊求和放大器的装置，该放大器利用多通道分析仪对电压进行数字显示；（3）一种改进版的阿德兰-克鲁克斯暗盒技术；以及（4）锗（锂）光谱仪法。每种技术都有其独特的优势：方法（1）能够直接观察波形；方法（2）可能是最准确且可重复的技术；方法（3）操作最为简便；方法（4）能够可视化X射线光谱。
