LEARNING OUTCOMES
After the end of the course, the students will have acquired general knowledge of the theory and the applications derived from it in the field of Medical Physics, which are a basic background for a course of his specialty. This will help them in the understanding of modern methods, technologies and general applications that have been established and are to be introduced in medical practice.
The course aims at:
(a) providing basic knowledge of medical physics with specific interest in biological systems, which are necessary for the understanding and interpretation of physiological phenomena and processes occurring in humans;
b) providing specialized knowledge of physics, on which modern therapeutic and diagnostic methods with applications in Medicine and health sciences are based;
(c) assuring in general, the students’ familiarity with modern medical technology and the rational way of thinking, that enables the estimation of physical quantities and numerical values and
d) familiarizing the students with the measurements and the experimental process, the way and the method of processing, evaluation and presentation of experimental data and results in the Physics laboratory.
