Please note

The information on this page is based on a course syllabus that is not yet valid.

Radiation has for several decades, been used to treat tumours. Different types of radiation such as photons, electrons, neutrons, protons or light ions can be used. The clinically most used treatment modalities are photons and electrons. The course gives a basic knowledge in the physical and biological effects of ionising radiation in tissue and an overview of methods for treatment optimisation to get the best therapy outcome.

Intended learning outcomes

The aim of the course is to give a basic knowledge in radiation physics and biological effects of ionising radiation in order to understand the principles of radiation therapy.

Course main content

Basic interaction processes of ionising radiation with matter. Basic concepts of dosimetry, dosimetric quantities and units. Accelerators for radiation therapy, principles of linear and circular accelerators. Beam transport through treatment head to patient. Optimal design of the therapy beam. Principles of optimal treatment planning. Algorithms for calculations of dose distribution in the patient. Quality control and assurance.
Introduction to biology of the cell. Basic chemical reactions in cells. Lesions produced by radiation in DNA molecules. Cell survival models. Radiation effects on normal tissues and tumours. The biological basis of radiotherapy, oxygen effect, dose rate dependence, dose fractionation.
