Assessment
Unaided Work:
During the course, students do individual and pair work; they carry out laboratory work according to the course topics; they study the given resources and scientific publications, using the knowledge obtained. Tasks related to the blood flow, the structure of syringes, blood transfusion, calculation of the human body parameters.
Assessment Criteria:
Students’ participation in practical classes, completion of individual assignment in the seminar and results of the practical work during the colloquium are evaluated. There are different types of test questions in the exam.

Learning Outcomes
Knowledge:		Upon successful fulfilment of the course requirements, students will have acquired the knowledge to: 1. Use medical physics terminology correctly. 2. Describe the role of physics and mathematics in medicine and in disease processes. 3. Describe the physical properties of parameters obtained in medical diagnosis and methods of obtaining them. 4. Explain basic principles in diagnosis of cardiovascular diseases. 5. Explain the structure of blood transfusion and syringes from the physico-mathematical perspective. 6. Name and evaluate the effects that the range of electromagnetic spectrum has on human health. 7. Explain the structure of laser, principles of operation, use in medicine and laser safety. 8. Explain the structure and operational principles of the simplest medical diagnostic equipment. 9. Assess the physical effects of the surrounding world on the human body and the protective measures against adverse effects.
Skills:		On completion of the study course, students will be able to: 1. Become familiar with the terms used in biophysics; 2. Apply the knowledge acquired to the assessment of cardiovascular diseases; 3. Evaluate the use of blood transfusions and syringes from a physico-mathematical point of view.
