Course learning objectives
- Identify and interpret the input data requirements for the cofiguration of beam models.
- Illustrate modeling 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.
Target Group
The course is primarily aimed at and recommended for medical physicists and experienced dosimetrists working in treatment planning. The participants should preferably have at least attended the ESTRO course "Physics for Clinical Radiotherapy" or equivalent and should have some practical experience in radiotherapy physics.
