Radiation Therapy 2: Physics, Equipment and Applications

Semester 1

This course investigates the principles and practices of modern radiotherapy procedures. Students are introduced to advanced techniques in external beam radiation therapy, brachytherapy and the fundamentals of quality assurance in a radiation oncology facility. The advancements in radiotherapy technologies have resulted in variety of complex treatment options that offers unique benefits to
patients of varying caner types. The medical physicist must have a good understanding of these treatment options to complement the multidisciplinary oncology teams. This is a core course for the qualification of clinical medical physicists.

  • Image guidance and verification in radiotherapy
  • Image registration
  • Brachytherapy including the ICRU Report 38 and the AAPM TG 43 formalism
  • Inverse Planning and optimization for intensity modulated radiation therapy (IMRT)
  • Ultrasound (US), portal imaging, in-vivo dosimetry (IVD)
  • Principles of quality management in radiation oncology
  • Coursework: 50%
    • Two in-course tests (2 x 1 hour) 20%
    • Three Practical Exercises 30%
  • Final Exam: 50%
    • One Three-hour written paper 50%
Learning Objectives: 

On successful completion of the course, students should be able to:
1. Apply the principles and competencies required in brachytherapy.
2. Implement concepts of advanced radiotherapy treatment planning and dose calculation.
3. Explain the use of ionization chambers for relative and absolute determination of absorbed dose to water in radiotherapy beams.
4. Assess factors influencing a dose measurement.
5. Apply concept and principles of an acceptance testing and commissioning programme.
6. Implement a quality assurance programme
