Equipments and techniques for diagnostics

Course objectives

ENG GENERAL The aim of the course is to provide students with specific knowledge on the main instrumentation used in the biomedical field. The theoretical activities, highly interdisciplinary, aim to develop the candidate's ability to connect the mathematical methods and techniques learned in other courses of study. The seminar activities, also carried out by external researchers, also aim to develop communication and interaction skills. SPECIFIC • Knowledge and understanding: The course aims to get the student to acquire knowledge for the instrumentation project for medical diagnostics. Particular attention is given to the design of nuclear magnetic resonance equipment, hospital monitors and ultrasound • Applying knowledge and understanding: The theoretical part is supplemented by application seminars on commercial solutions and research activities in various areas of medical instrumentation, including innovative such as impedance tomography and radar applications in medicine • Making judgements: The theoretical, highly interdisciplinary activities aim to develop the candidate's ability to link mathematical methods and techniques learned in other courses of study • Communication skills: Seminar activities, also carried out by external researchers, are also aimed at developing communication and interaction skills. • Learning skills: . In addition to the teaching material provided, the student is encouraged to study in an autonomous way using the scientific literature made available and other material available on the web.
