Obiettivi dell'insegnamento

Goal of the course is to provide a basic knowledge of the most significant use of sensors, circuits, electronics systems in the biomedical instrumentation, starting from recalling the basic principles of the instrument/technique and then analysing and designing the components and electronics circuits (analog and digital) employed in the instrument. The tipologies of instruments considered in the course are: conventional and advanced instrumentation for the analysis of signals of biological origin, systems for medical imaging based on the use of radiation (X and gamma rays). Special focus of the course will regard application of microelectronic technology and circuits to the considered topics.
