Target volume determination - From imaging to margins (Postponed to 2022)

This course is for trainees in radiation oncology and physics. It covers the application of anatomical knowledge in daily clinical practice, the optimal imaging requirements for treatment planning and delivery for a wide variety of tumours, how to determine adequate margins, and how to initiate an IGRT protocol.

The course is aimed at trainees in radiation oncology and radiotherapy physics with at least one year’s experience, diagnostic radiologists with an interest in cancer imaging and radiation therapists (RTTs) with special interest in contouring and treatment planning. However, any senior who would like to refresh part of her/his knowledge would benefit from this course.

This course aims to:

  • Make understandable the principles and limitations of different imaging modalities utilised for target volume definition (TVD) such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET) 
  • Present the need for TVD and planning nomenclatures for primary tumour, nodal regions and organs-at-risk 
  • Explain treatment techniques such as IMRT and VMAT, image guided radiotherapy (IGRT), and the concept of adaptive radiotherapy 
  • Provide appreciation for the limitations of current imaging modalities for TVD and review “state-of-the-art” imaging modalities for TVD 
  • Explore the use of functional and molecular imaging in TVD for biological targets and their use in radiotherapy 
  • Review the diagnostic imaging and therapy interface for image registration, deformation and verification as well as margin determination.

Learning Outcomes

By the end of this course participants should be able to:

  • Have a comprehensive understanding of all parts of the planning process and also plan evaluation for intensity modulated radiotherapy (both stepand-shoot IMRT and VMAT)
  • Increase accuracy as well as effectiveness in the planning process
  • Understand the basis for comparing different plans for the same case
  • Understand the problem of competing priorities in planning
  • Appreciate the concept of plan optimisation.
