Medical accelerator safety considerations: report of AAPM Radiation Therapy Committee Task Group No. 35

Area of Science:

• Medical Physics
• Radiation Oncology
• Healthcare Technology Safety

Background:

• Medical accelerators are complex tools requiring specialized user knowledge.
• Contemporary equipment necessitates greater user responsibility in operation.
• Effective use relies on close collaboration between users and manufacturers.

Purpose of the Study:

• To outline essential safety measures for medical accelerator operation.
• To emphasize the need for clear procedural instructions and training.
• To provide recommendations for mitigating equipment failure consequences.

Main Methods:

• Review of current safety practices in medical accelerator use.
• Development of guidelines for procedural instruction and technologist training.
• Formulation of recommendations for equipment malfunction response and quality assurance.

Main Results:

• Complex procedures require unambiguous written instructions at the control console.
• Thorough "hands-on" training is crucial before technologists assume treatment responsibilities.
• A list of appropriate contacts for unexpected machine behavior is recommended.

Conclusions:

• Continuous vigilance and ongoing quality assurance programs are key to safety.
• Implementing detailed procedures and training enhances safe operation.
• Recommendations can be readily implemented at treatment centers to improve safety protocols.
