[POSTPONED UNTIL 2022] Advanced Physics for Brachytherapy

Athens, Greece

Seeking to advance your expertise in brachytherapy physics? The Advanced Physics for Brachytherapy course provides a modern update on the clinical standard-of-care and an in depth look into the scientific foundation necessary to qualify as a brachytherapy physics expert in practice and research.

[ Early deadline: 1 July 2020 ]

The course is primarily designed for medical physicists interested in expanding their knowledge in the field of brachytherapy physics. A basic background in the sub-specialty is required, as supported by (preferably) at least one year of experience in clinical practice, or participation in a relevant course (such as the Comprehensive and Practical Brachytherapy teaching course). The course could also serve as a refresher or an interactive update on recent developments in the field of brachytherapy for senior medical physicists.

  • Provide a detailed review of modern 3D treatment planning techniques and prescription concepts including: imaging, anatomy segmentation and source localisation methods, optimization methods and strategies, treatment plan evaluation, the need for quality assurance, and concepts of risk assessment
  • Provide an overview of essential quality assurance aspects, in vivo dosimetry, treatment verification techniques and associated recent developments
  • Review available knowledge on uncertainties and their clinical impact in modern brachytherapy
  • Offer an overview of upcoming technological advancements in implantation and treatment delivery.

Learning Outcomes

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

  • In-depth understanding of 3D imaging role in modern brachytherapy
