Sample interview questions: How do you handle the calibration and maintenance of radiation therapy equipment?
Sample answer:
Calibration and Maintenance of Radiation Therapy Equipment
As a Medical Physicist specializing in Radiation Therapy, the calibration and maintenance of radiation therapy equipment are crucial responsibilities to ensure accurate and safe treatment delivery. Here’s how I approach these tasks:
Calibration:
- Regular Protocols: Establish and follow standardized calibration protocols compliant with national and international standards (e.g., AAPM, IEC).
- Calibration Frequency: Determine the optimal calibration intervals based on equipment type, usage, and regulatory requirements.
- Reference Equipment: Use traceable and calibrated reference instruments, such as ionization chambers, to ensure accurate measurements.
- Calibration Factors: Calculate and record calibration factors to convert measured readings into absolute dose values.
- Verification and Traceability: Conduct regular verification checks to confirm calibration accuracy and maintain traceability to national standards.
Maintenance:
- Preventative Maintenance: Implement a preventative maintenance schedule to identify potential issues before they affect equipment performance.
- Routine Inspections: Conduct regu… Read full answer
