Methods and Techniques in Radiotherapy

Knowledge acquired in Medical Image Processing UC.

This is a Curricular Unit (CU) central to the training of future graduates, in which content will be taught on the techniques of external radiotherapy and brachytherapy treatment available in a radiotherapy service.

The teaching methodologies described above, in theoretical terms, aim to introduce new core subjects of the Degree and consolidate contents taught in previous CUs. The use of the expository-active method calls for the use of multimedia contents as an aid to the exhibition. The participation of students will be encouraged in order to understand the content taught.

The theoretical-practical aspect will appeal to the reasoning elaborated in relation to the contents of the UC, in this sense it will appeal to the simulation in class of clinical problems/examples aimed at raising technical-professional awareness in Medical Imaging and Radiotherapy.

The student must acquire knowledge about:

– Types of treatment

– Techniques of External Radiotherapy and Brachytherapy, used for treatments with Ionizing Radiation, allowing for their understanding and identification.

The student must acquire skills to:

– Recognize treatment techniques regarding their therapeutic indication

– Identify, choose and build adequate positioning and immobilization means for each situation, taking into account the patient’s technique, pathology and physical condition. Know the radiation sources used in each technique and their main applications and areas of action.

The student must acquire skills to:

– Use, apply and reproduce treatment techniques

– Use the appropriate positioning and immobilization means

– Use treatment verification systems

– Apply the concepts of radioprotection to the patient and the professional

Evolution of Radiotherapy
