Summary

Quality assurance (QA) protocols are crucial for mobile C-arm fluoroscopy systems, often overlooked in diagnostic imaging. This study developed and applied a QA protocol, revealing significant performance variations and highlighting the need for standardized testing to ensure optimal image quality and radiation safety.

Area of Science:

  • Medical Physics
  • Radiological Sciences
  • Diagnostic Imaging Technology

Background:

  • Quality assurance (QA) is vital for diagnostic imaging equipment.
  • Mobile C-arm fluoroscopy systems are increasingly used in various clinical settings.
  • Existing QA literature inadequately addresses mobile C-arm fluoroscopy systems due to accessibility and protocol limitations.

Purpose of the Study:

  • To review existing literature on QA for mobile C-arm fluoroscopy.
  • To design a comprehensive QA protocol for this specific equipment.
  • To survey the performance of clinical C-arm systems using the developed protocol.

Main Methods:

  • Literature review to identify gaps in QA for mobile C-arms.
  • Development of a novel QA protocol encompassing mechanical, electrical, radiation safety, and image quality aspects.

    • Main Results:

    • Significant performance variations were observed among the surveyed C-arm systems.
    • Substantial differences in input air kerma rate to the image receptor were identified.
    • The designed QA protocol effectively assessed system performance.

    Conclusions:

    • A standardized QA protocol is essential for mobile C-arm fluoroscopy systems.
    • Implementing such protocols can establish optimal performance benchmarks.
    • This work supports the development of criteria for system decommissioning or replacement.
