An electronic instrument with digital readout has been designed and constructed for indirect determination of the kVp applied to diagnostic x-ray tubes. The signals from two detectors exposed simultaneously to a differentially filtered x-ray beam are processed by analog computing circuitry to yield an output signal directly proportional to the applied peak kilovoltage. Theory and preliminary results are presented and discussed.
已设计并制造出一种带有数字读数的电子仪器，用于间接测定施加于诊断用X射线管的千伏峰值（kVp）。来自两个同时暴露于经不同滤波的X射线束的探测器的信号，由模拟计算电路进行处理，以产生与所施加的峰值千伏直接成比例的输出信号。文中给出并讨论了相关理论和初步结果。
