Dosimetry in radiotherapy. Planning and implementation of a percutaneous radiation exposure on an anthropomorphic phantom. Verification of the resulting dose distribution.

Introduction to the fundamentals of medical radiation physics. Functional chain due to radiation exposure from the primary physical effect to the radiobiological and medically manifest secondary effects. Dosimetric concepts of radiation protection in medicine. Mode of action of radiation sources used in medicine and its illustration by means of Monte Carlo simulations.

Applications of ionizing radiation in medicine such as radiation therapy, nuclear medicine and radiation diagnostics. Theory of dosimetry based on cavity theory and clinical consequences. Fundamentals of dose calculation, optimization and evaluation. Concepts of external beam radiation therapy and brachytherapy. Recent and future developments: IMRT, IGRT, SRS/SBRT, particle therapy.

The aim of this lecture is to study different aspects of medical physics from the practical view. One main component is to assist the students for getting in contact with medical physicists and to build a platform for a dialogue. For this purpose, a number of lecturers from entire Switzerland are reportig about their work as a medical physicist.
