Foundamentals of Measurement techniques and Biomedical Instrumentation.

Learning outcomes
The course is aiming to present the main advanced measurement methods for the biomedical engineering and the medicine. In particular, the course will provide advanced knowledge on the technologies and the biomedical instrumentation used in medicine for diagnosis and treatment scopes, describing their working principles and analyzing their main technical characteristics. These knowledges, together with the ones acquired in the Laurea degree courses, and in particular in the course of misure meccaniche e strumentazione biomedica, will allow the student to gain a detailed knowledge on the measurement methodologies, technologies and biomedical instrumentation presently available.
The content of the course will allow the student to efficiently operate in the biomedical engineering sector as a designer of systems or as developer of novel products and technologies. The student will have to be able to analyze the working principle of the biomedical instrumentation and to understand the technologies commonly utilize din the biomedical sector. Moreover, he will develop specific skills for the classification of the instrumentation, for the analysis of the measurement performances of systems and for the identifications of main critical issues in the installation and use of such devices. Finally, the student will have to develop skills for teamwork
The student will develop the skill to analyze complex measurement systems, identifying their working principles, the main components and the most relevant measurement characteristics. The didactic activity will also include the laboratory sessions and the (voluntary) preparation of a project aiming to analyze and present a biomedical system of high-technology level.

Development of the examination
The exam consists in an oral discussion on the course topics. During this exam, the student has to present the various instrumentation, to answer to the eventual questions relative to the measurement methods, object of the course, and to be able to critically discuss the various course topics.

The evaluation criteria are: Completeness of the exposition, student skills on clearly expose the argument requested will be used as evaluation criteria and to analyse the design and opeartive aspects of the different instrumentations. The correct use of terminology and of correct instruments and methods will also be taken in consideration.

The measurement criteria are: Capacity to present in an exhaustive manner the course argument and coherent and critical analysis of the arguments object of the exam.

Full mark will be given to the student if during the oral exam he/she will demonstrate a full knowledge of the course arguments, an autonomous and complete capacity of analysis and presentation of the course arguments.
