FALCON (Fellowship in Anatomic DeLineation and CONtouring) is the multifunctional ESTRO platform for contouring and delineation. At ESTRO 2023 in Vienna, ESTRO will be offering 5 different contouring workshops. 

Target Audience

The delineation workshops are aimed at junior clinical or radiation oncologists who want to improve their contouring skills or at more senior specialists who want to refresh and validate their knowledge and skills in this field.

Structure of the Workshop

Each of the workshop sessions last for two hours. The session will cover the following areas:

  • Presentation of the delineation guidelines
  • Comment of participants’ contours and comparison to the reference contours
  • Discussion between participants and experts

Practical Information and Registration

Attendees need to register separately to the contouring workshops. They are not part of the general congress fee.

Workshop participants are required to bring their own computer.  ESTRO is not able to provide any computers for attendees.


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 workshops by comparing them with those from experts and other participants
  • Learn the guidelines and best practices proposed by the experts
  • Discuss with experts and panellists
  • Communicate and use the delineation guidelines to further integrate them into your daily practice
