Base Knowledge
Radiobiology and Radiation Physics
Teaching Methodologies
Theoretical
The preferred method is the expository method, taking into account the learning of facts and concepts. The Case Study is also applied during the classes, whenever practical cases are used to demonstrate planning concepts and rules.
Theoretical-practice
The case study is privileged, since the students will work on specific cases of patients with real pathologies.
Learning Results
The student must acquire:
• knowledge of dose calculation algorithms, volume definition, planning techniques, radiobiology for radiotherapy,
evaluation methods of a treatment plan, radiation beam features
• skills to identify the best radiotherapy technique for a given site, to indicate the most appropriate dose calculation
algorithm, to apply organs at risk tolerance tables, to evaluate a treatment plan considering target volume and
organs at risk doses
• competences to execute a simple treatment plan, to use the planning system tools for the delineation of organs at
risk, to identify and apply the different available beam modifiers
