AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

Understanding how the physiology of different body parts follows the fundamental principles of physics.
Applying simple models in order to predict physiological quantities and their change in presence of anatomical dysfunctions, of particular environmental conditions or harmful activities.
Understanding the physics underlying some diagnostic methodologies. Providing the ability to link the outcome of clinical measurements to physical parameters that are related to the operation of internal organs.
Understanding the physical principles underlying the operation of medical devices

TEACHING METHODS

Physics and Biophysics is a 43-hour course. The activity is divided into lectures (31 hours) and exercise classes. The exercises deal with both topics already introduced during lectures and with supplemental applicative examples (12 hours).

EXAMS

EXAM DESCRIPTION

Written exam (9 multiple choice test questions and 5 problems with numerical solution on the physics part together with 6 multiple choice test questions on the Informatics part; the overall testing time is 3 hours

ASSESSMENT METHODS

Evaluation methods are based on partial or global exams where the student shall show a proper knowledge of the course topics, and the ability to use the related concepts for the quantification of the physical quantities relevant in medicine
The minimum score required to pass the exam is 18/30. In order to achieve 30/30 or 30/30 cum laude excellent knowledge is required. During the class period, self-evaluation tests on the Aulaweb platform are proposed. The aim of these tests is to provide the student with an instrument to evaluate his/her progress in the preparation.
