Prerequisites for admission
Basic principles of mathematics and physics, as required by the admission notice. Powers, logarithms, algebraic calculation, Euclidean geometry (polygons, circle, measures of lengths, surfaces and volumes), elements of trigonometry. Basic notions on the principles of mechanics, thermodynamics and electrostatics.
Teaching methods
The program will be carried out through lectures (5 CFU) with the aid of teaching material (slides) and group exercises (1 ECTS) in which students carry out, personally and / or in small groups, a series of exercises proposed by the teacher and under her guidance. The teaching uses the Ariel platform to provide students with teaching materials ( slides, videos or website links ) on specific medical physics topics not easily found in general physics textbooks.

Assessment methods and Criteria
The exam consists:
· in a preliminary written test consisting of 20 multiple-choice questions (only one correct answer), time available 60 minutes. The evaluation will check the full resolution method of each question. Each unjustified, not given or incorrect answers will give a score of 0. The score range will be A - D for approved tests. Passing the written test allows admission to the oral exam. With D the maximum final mark will be 25.
of an oral test in which the student will be evaluated for her/his ability to express with clarity, precision and reasoning skill the topics covered during the course.
Passing the test will result in a mark expressed in thirtieths.
