MEDICAL PHYSICS AND STATISTICS

Module MEDICAL PHYSICS

The aim of the Physics module is the teaching of physics and basic mathematics with simple applications to biomedical problems. We want to obtain the homogeneity of preparation for all students in view of the specific knowledge required of them in the continuation of the Degree Course. In particular, the student will have to acquire the knowledge of some basic physical laws and techniques for the understanding of physiological, biological and medical processes and will have to learn basic concepts useful for the correct use of the instrumentation used in the professional field

Lectures and classroom exercises. If the teaching is given in a mixed or remote mode, the necessary changes with respect to what was previously stated may be introduced, in order to comply with the program envisaged and reported in the syllabus.

elementary knowledge of algebra and geometry is required

Oral exam based on the topics of the course.

Verification of learning can also be carried out electronically, should the conditions require it.
