Dose Modelling Verification for External Beam Radiotherapy

Barcelona, Spain

Bemused by external beam modelling? Dazed by dose calculation algorithms? This course shines the spotlight on treatment planning systems and dose verification for external beam therapy.

[ Early deadline: 18 February 2020 ]

The course is primarily aimed at and recommended for medical physicists and experienced dosimetrists working in treatment planning. The participants should preferably have some practical experience in radiotherapy physics and treatment planning systems. A good medical physics background is required.

The course aims to: 

  • Review external beam radiotherapy physics and beam modelling
  • Make understandable the concepts behind multi-source modelling and dose calculation algorithms in state-of-the-art treatment planning systems
  • Identify and describe the important aspects of commissioning treatment planning systems
  • Review dosimetry equipment and dose verification methods of importance for commissioning and verification measurements
  • Enable practical implementation of concepts for dose verification in advanced external beam therapy. 

 

Learning Outcomes

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

  • Identify and interpret the input data requirements for the configuration of beam models
  • Illustrate modelling of the patient, treatment beam and energy deposition in the treatment planning process
  • Present the concepts behind simple and advanced dose calculation algorithms as implemented on modern treatment planning systems and monitor unit or dose calculation check software tools 
  • Compare and critically evaluate the tools and methods available for the verification of the calculated dose
  • Assess aspects of quality assurance specific to the treatment planning process

Course Content

  • Review of basic concepts of fluence, radiation transport and convolution 
  • Linac head design and multisource models 
  • Patient and phantom characterisation for treatment planning systems 
  • Point kernel, pencil beam and grid based approaches to dose calculation 
  • 1D, 2D and 3D detectors for measurement 
  • Use of measured data in beam models  
  • Monitor unit calculation and relation to beam models 
  • Commissioning and quality assurance of a treatment planning system 
  • Dose based metrics 
  • Practical exercises on monitor unit calculation and modelling

Prerequisites

Before commencing this course you should preferably have attended the ESTRO course ‘Physics for Modern Radiotherapy’ or equivalent.

Teaching Methods

  • 21 hours of lectures 
  • 4 hours of practical workshops 
  • 2 hours of Q&A 

The course consists of didactic lectures, interactive discussion sessions and practical calculation and modelling sessions. Lectures and preparation workshops will be given on monitor unit calculation and beam modelling. Participants will engage in realistic monitor unit calculation scenario exercises. Participants will also undertake computer-based modelling of basic models for photon beam head scatter and kernel based dose calculations. 

Methods of Assessment

  • MCQ  
  • Q&A 
  • Practical exercises 
  • Evaluation form.
