SCIENZE DELLA PREVENZIONE RADIOPROTEZIONE E CONTROLLI DI QUALITA'

Learning Objectives

• 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.

• Radiobiology e Radioprotection

  To acquire knowledge about the following topics:

  • Theoretical principles of radiobiology
  • Interaction of ionizing radiations with human body
  • Principles of dose fractionation in radiotehrapy
  • Technical aspects of radioprotection
• The physics of instrumentation and devices

  The main objective of the lectures is the knowledge of the physics fundamentals of instrumentation useful to medical diagnostics and therapy.
