BIOMEDICAL INSTRUMENTATION II

Course objectives

During the module (9CFU) the aims of the course are the physical bases and design fundamentals of biomedical instrumentation such as clinical ultrasound systems, Computed Tomography and Magnetic Resonance Imaging. The course treats also an overview of past and actual technologies of the cited biomedical equipments. The students will acquire the knowledge of the working principles, design techniques and tecnological improvements. They should be able to comprehend and perform the principal test procedures for assessing the performances of biomedical equipments. They should also be able to manage the design criteria of said equipments. In a subsequent module (3 CFU) the aims of the course are designed to deepen the transducer array design criteria applied in ultrasonography and introduce the basic concepts of quality control of the sonographic image known in the scientific literature as Quality Assurance Test. At the end of the learning path the student must be able to acquire the knowledge and methodologies needed to identify the control protocol of the specific image quality for the different types of probes

Books
1) F.P. Branca "Fondamenti di Ingegneria Clinica" - Volume II - Ed. Springer. 2) lecture notes and other material distributed by the teacher.
Exam mode
The (oral) examination is usually carried out around two themes which correspond to the three main sections of the course: Clinical Ultrasound, CT and MRI The parameters which are utilized for evaluating the candidate are: - Knowledge and ability to expose the various themes and topics encountered during the course - The proper adoption of technical terms - The ability to autonomously revise the course topics - The ability to refer the knowledges acquired during the previous studies and to adopt them properly ad accordingly in order to gain a comprehensive and strict speech during the examination
