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.  The special multidisciplinary workshop is open to all but is especially targeted at RTT who contour in their clinical work.


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.
