    Routine x-ray waveform analysis during acceptance testing identified generator faults, preventing inconsistent radiographs. Ongoing monitoring revealed malfunctions, highlighting the need for quality control programs in diagnostic imaging.

    Area of Science:

    • Medical Physics
    • Diagnostic Imaging Technology

    Background:

    • Radiation waveforms visualize x-ray intensity fluctuations over time.
    • Quality control in diagnostic imaging is crucial for reliable patient diagnosis.

    Purpose of the Study:

    • To assess the effectiveness of acceptance testing using radiation waveforms for new x-ray units.
    • To evaluate the incidence of generator-related faults and their impact on radiograph quality.
    • To determine the necessity of ongoing waveform monitoring and quality control.

    Main Methods:

    • Performed acceptance testing on 15 newly installed x-ray units.
    • Analyzed radiation waveforms to detect generator-related faults.
    • Identified faults that could lead to inconsistently exposed radiographs.

  • Monitored unit performance after one year of clinical use.

    • Main Results:

    • Seven of 15 units exhibited 13 generator-related faults during acceptance testing.
    • Six of these faults would have compromised radiograph consistency in four units.
    • Five units showed serious malfunctions after one year of use.

    Conclusions:

    • Acceptance testing with radiation waveform analysis is essential for identifying and correcting pre-clinical faults.
    • Regular waveform monitoring and a proactive generator quality control program are vital for maintaining diagnostic imaging equipment reliability.
