This 2-days course is organised by the Advanced Medical & Dental Institute (AMDI) USM in collaboration with USM Medical Centre Bertam. lt is designed to provide the necessary theoretical and practical background in medical physics. The first day of the course comprises of a series of lecture on the basic and physic theories of linac calibration and focusing on the QA aspect. The practical session on Day-2 includes step-by-step demonstration linac calibratios according to TRS-398 The course is aimed primarily for medical physicists, but shouId aIso benefit engineers, researchers, postgraduate students, manufacturer's representative, and anyone interested to update their knowledge and understanding on this topic.
Background and Rationale
Proper calibration of radiotherapy linear accelerators is fundamental to the accurate and safe delivery of radiotherapy treatment. This course provides an integrated practical and theoretical approach to radiotherapy linac calibration, grounded in the principles of absorbed dose to water standards using TRS-398 protocol. Emphasis is placed on the hands-on implementation supported by fundamental understanding, empowering participants to perform clinical calibration with confidence.
Learning Objectives
Participants will:
- Understand the theoretical basis of absorbed dose to water calibration.
- Apply reference dosimetry protocols for linac photon and electron beams.
- Select appropriate ionisation chambers and apply beam quality correction factors (kQ).
- Perform chamber cross-calibration and interpret calibration certificates.
- Evaluate measurement uncertainties.
Detailed programme can be found in the PDF file.
The course will be delivered by experts in the field including an experienced physicist from Australia.
Target Participants
- Clinical medical physicists
- Medical physics trainees
- Radiation therapist/Radiotherapy technologists with dosimetry responsibilities
- Postgraduate students in medical physics
Expected Outcomes
- Confident execution of linac reference calibration following international standards.
- Standardised procedures and reduced variation in dose output checks.
- Improved understanding of measurement uncertainties and their clinical relevance.
