Preventive Care, radiation protection and quality control

Module Electrical and electronic measurements

The specific training objectives, which are functional to the professional figure that the course intends to train, that is  the expert in the field of electronic electrical measurements, sensors and transduction elements inherent the field of  radiology medical for pictures and radiotherapy.

In this context, the course aims to train technicians with a suitable basic scientific training and adequate competences  of the general technical-scientific content and methods of electronic engineering with particular emphasis on the basic of metrology.

Knowledge and understanding 

The student will acquire knowledge on metrology, measurement systems, sensors and transducers also in the context of prevention and radiation protection. The main applications will be related to the fields of electronic engineering polarized towards a professionalizing aspect in accordance with the Degree Course.

Applying knowledge and understanding

At the end of the course, students will have the necessary skills to perform measurements, with appropriate methodology and systems, identifying their main sections and functionalities. 

Making judgements

Students will acquire autonomy of judgment for an accurate analysis of the systems considered.

Communication skills

The student will reinforce the technical language of measurement systems with the goal of being able to adequately present him/herself on the job market with adequate skills and an appropriate technical profile. 

Learning skills

The student will be able to autonomously expand his knowledge of electrical and electronic measurements also through in-depth study of reference texts, on articles of specialized scientific journals.

Frontal lessons

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
