The main aim of the course is to transfer to the students the physical basis of the method as well as the scientific procedure for the applications of radio diagnosis and radio therapy instrumentation. The final goal for the students involves the fundamental concepts of physics and their implications in the biomedical, technical and technological fields of the equipment used in clinical radiological practices for diagnosis and therapy, with particular reference to some relevant topics for preparatory courses subsequent technical-applications. For instance: the use of traditional and digital radiography and fluoroscopy, creation of analogue and digital images, management of digital images. The student is expected to learn how solve simple physics problems in topics most directly connected to the biomedical, technical and technological fields and to become capable to make quantitative assessments and estimates of the phenomena analyzed.
