Summary
A new Varian linear accelerator (LINAC) was commissioned at Kaohsiung Medical College Hospital. Comprehensive tests ensured its safe and effective operation for high-quality radiation therapy.
Area of Science:
- Medical Physics
- Radiation Oncology
Background:
- Installation of a Varian 2100C medical linear accelerator (LINAC) at Kaohsiung Medical College Hospital.
- The LINAC provides 6 and 10 MV X-ray beams and 6, 9, 12, 16, and 20 MeV electron beams.
Purpose of the Study:
- To detail the commissioning process of a new Varian 2100C LINAC.
- To ensure the LINAC meets safety and performance standards for clinical use.
Main Methods:
- Performed sequential acceptance tests by medical physicists and engineers.
- Conducted dose determination and environmental radiation surveys using ion chambers, phantoms, and survey meters.
- Calculated radiation dose according to the American Association of the Physicists in Medicine (AAPM) Task Group 21 protocol.
Main Results:
- Successful completion of acceptance tests and dose measurements.
- Environmental radiation levels were assessed.
- The commissioning procedure facilitated the licensing process with the Atomic Energy Council (AEC).
Conclusions:
- A robust quality assurance (QA) program was established post-licensing.
- Continuous QA ensures the Varian LINAC maintains high standards for radiation therapy.
- The commissioning and QA processes are critical for safe and effective LINAC operation.
