A critical overview of acceptance testing using various measured indices

Area of Science:

• Medical Physics
• Radiological Engineering
• Health Physics

Background:

• European Directive 97/43/EURATOM mandates acceptance testing for all new radiological equipment before clinical use.
• Implementation of this directive into member state law is essential for radiation protection.
• Digital fluorography systems require thorough evaluation to ensure safety and efficacy.

Purpose of the Study:

• To perform acceptance testing on thirteen digital fluorography systems in accordance with European directives and international standards.
• To evaluate the performance, image quality, and safety aspects of newly installed radiological equipment.
• To identify any deficiencies or problems with the digital fluorography systems prior to clinical application.

Main Methods:

• Testing of thirteen digital fluorography systems across six Irish hospitals, including interventional, cardiac catheterisation, and vascular systems.
• Adherence to published international guidelines and standards for radiological equipment testing.
• Comprehensive analysis of X-ray tube and generator performance, operating dose levels, image quality, and electrical, mechanical, and radiation safety.

Main Results:

• All thirteen digital fluorography systems exhibited problems during acceptance testing.
• Approximately 70% of the tested systems demonstrated significant issues requiring attention.
• Identified problems spanned performance, safety, and image quality parameters.

Conclusions:

• Acceptance testing is vital for ensuring the safety and proper functioning of radiological equipment.
• The high percentage of systems with significant problems underscores the necessity of pre-clinical evaluations.
• This study reinforces the importance of adhering to regulatory requirements for medical exposures.
