Noninvasive monitoring of x-ray output waveforms during acceptance testing, quality of control, and troubleshooting is beneficial in an ongoing radiographic quality assurance program. The intent of waveform monitoring is to watch for abnormalities that provide additional information about the condition of the x-ray system. Because waveform monitoring is performed generally in conjunction with other quality control procedures, few, if any, additional exposures are needed and length of the testing time is affected minimally. In six years of experience with acceptance testing, quality control, and troubleshooting on more than 160 radiographic and fluoroscopic units, noninvasive waveform monitoring has detected numerous abnormalities that would have affected image quality, generator calibration, and equipment life.
在验收测试、质量控制和故障排除期间对X射线输出波形进行无创监测，对持续进行的放射成像质量保证计划有益。波形监测的目的是留意异常情况，这些异常可为X射线系统的状况提供更多信息。由于波形监测通常与其他质量控制程序一起执行，因此几乎不需要额外的照射（如果需要，也很少），并且测试时间的长度受到的影响最小。在对160多个放射成像和荧光透视设备进行验收测试、质量控制和故障排除的六年经验中，无创波形监测已检测到许多会影响图像质量、发生器校准和设备寿命的异常情况。
