Clinical Dosimetry

Theoretical classes aim at the detailed presentation of the syllabus. In them an expositive-active methodology is used,appealing to the direct intervention of the students, favorably favoring an abundant iconography to the detriment of merelytheoretical-descriptive teaching. The discussion of real clinical cases allows to consolidate the exposed contents.
The theoretical-practical component is developed using the institution’s existing planning system. Classes are taught withpractical examples of planning in different anatomical locations to be developed by students with the supervision of the teacher.
Students will be encouraged to search in databases, scientific publications alluding to and explaining the contents taught.
Two written tests will be carried out using open, closed and multiple choice questions (each with a minimum score of 9.5). Thefinal grade is given by the average of the two tests.

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
