Intensity Modulated Radiotherapy Techniques (Static or rotational IMRT-techniques)
rather than uniform intensity techniques give the ability to conform dose distributions
to a variety of complex tumour sites/volumes while sparing nearby critical normal
tissue structures (OAR) as possible.
The QUANTEC reports have summarised the evidence from a wide range of studies relating
to the dose tolerance of the main OARs. Several of the reports highlight the issue
of the normal tissue delineation considering both anatomical and functional aspects.
In order to achieve a greater level of accuracy in the definition of OARs, there is an
urgent need to improve the knowledge of the anatomical limits of some selected
structures. It is therefore important to become familiar with contouring procedures
on the different imaging modalities implemented in the treatment planning systems,
without neglecting the organ dose-volume tolerance.
This course will specifically focus on the anatomical definition of normal structures
within the head and neck, thorax and pelvic regions.
An introductory lecture will illustrate the meaning of OAR delineation within the
frame of the QUANTEC report.
The following section will be organised in:
1) A first theoretical part for each site, where an expert will give an overview of
the delineation of the selected organ/s at risk in accordance with the QUANTEC
recommendations,
2) It will be followed by a practical session in which the participants will have the
opportunity to apply their knowledge in practice with the support of the faculty.
They will be asked to contour organs on FALCON, an E-learning software tool
based on the EDUCASE platform of ESTRO which has already been used successfully
during previous workshops on target volume delineation.
In preparation for the course and to ensure maximum benefit, the participants will be

asked to use the FALCON platform at home to delineate selected organs at risk. The
same exercise will be repeated during the course and, after the experts’ lectures, the
comparison between the exercises will be discussed by the teachers using FALCON tools.
As an outcome of the course we would like the participants to review their clinical
practice in the context of the new recommendations of normal structure delineation
and QUANTEC guidelines.

This course is designed for radiation technologists involved in planning and radiation
oncologists in training.
