Radiation waveforms show the variation of x-ray intensity with time. Acceptance testing was done on 15 newly installed x-ray units and the waveforms of seven showed a total of 13 generator-related faults. Of the 13 faults, six would have caused inconsistently exposed radiographs in four units. These faults were corrected before the units were used clinically. After one year of use, the waveforms from five of the 15 units showed serious malfunctions. This illustrates the need for acceptance testing, radiation waveform monitoring and an active generator quality control program.
辐射波形显示了X射线强度随时间的变化。对15台新安装的X射线设备进行了验收测试，其中7台设备的波形显示出总共13个与发生器相关的故障。在这13个故障中，有6个会导致4台设备的X线片曝光不一致。这些故障在设备投入临床使用前已得到纠正。使用一年后，15台设备中有5台的波形显示出严重故障。这说明了验收测试、辐射波形监测和积极的发生器质量控制程序的必要性。
