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.
- Clinical survey of 10 mobile C-arm fluoroscopy systems.
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.
