Course description This course covers practical and theoretical aspects on medical physics in the field of radiotherapy.

First the basic radiation physics will be discussed: e.g.
production of radiation, radioactive decay, characteristics of ionizing radiation, interaction with matter and measurement of absorbed dose.

The next part covers the essentials of dose calculation using various algorithms and dose optimization such as Intensity modulated therapy (IMRT) and volumetric arc therapy (VMAT).

Third topic is image guided radiotherapy (IGRT): e.g. inter- and intrafraction motion, position verification devices (electronic portal imaging device, cone-beam CT and MRI), real time imaging and various methods to deal with motion.

Finally topics in the field of MRI guided treatment will be discussed: e.g. dose delivery in magnetic fields, MRI linac design, workflow and plan adaptation.

Examination:

• Written exam: 80%; attendance to the practical work is obligatory to qualify for examination
• Oral presentation and discussion: 20%

The weights indicated above are applied to calculate the final mark. To pass the course the grade for each component must be a 5.0 or higher and the final mark must be an unrounded 5.5 or higher. (Anglo-Saxon grade mark D)
