Target audience

The delineation workshops are aimed at all radiation oncology professionals who want to improve their contouring skills. Three types of cases are dedicated to radiation oncologists: a common case, a rare case and a more advanced case. The OAR case is especially targeted to radiation therapists (RTTs) and dosimetrists.

Structure workshops

  • Presentation of the clinical case and the delineation exercise 
  • Explanation of the contouring software 
  • 20 minutes for the first delineation on site 
  • Presentation of the delineation guidelines 
  • 20 minutes for the second delineation on site 
  • Discussion between experts and participants

Practical arrangements

  • Participants should bring their own laptops 
  • Wifi and wired connection will be available 

  • Participants will be limited to 40 per workshop to keep a strong interactivity in the group.


FALCON workshops have been organised at ESTRO congresses since 2010 and have been growing steadily in popularity. 
Attending a FALCON workshop offers the opportunity for individual professionals to: 

  • Validate their contouring practice during live workshops by comparing them with those from experts and other participants 
  • Learn the indications proposed by the experts that coordinate the workshops 
  • Discuss with other participants, experts and panelists 
  • Communicate and use the delineation guidelines in order to further integrate them into daily practice.
