Learning Objectives

Physics
The aim of the course is the achievement by the student of descriptive and predictive ability of physics applied to biological systems. The review, in the medical field, of the scientific method in terms of language, models and representation of the mechanical, thermal, electromagnetic phenomena represents a specific objective as well as the knowledge of basic physical principles of the diagnostic and therapeutic techniques used in modern medicine.

The subjects that will be covered are: fluid mechanics and its implications in hemodynamic; wave mechanics with specific developments relating to sound and hearing; the use of ultrasounds in medicine; vision and optical instruments; interaction of radiation with matter; generation, use and biological effects of ionizing radiation; dosimetry and radiation protection.

The scientific field of reference is Applied Physics (FIS/07).
