About Study Course
Objective
1. To promote acquisition of knowledge of the main use of lasers in medicine and to provide a basic understanding of tissue optics.
2. To provide theoretical knowledge of lasers and intense pulsed light therapy applications in medicine.
3. To teach students to evaluate the impact of lasers on the human body, tissues and to predict the changes in laser power; know security tools, basic rules and standards for working with lasers; use and follow safety rules at work with lasers.
Preliminary Knowledge
Knowledge of mathematics and physics. Before attending practical classes, it is necessary to attend lectures in this course and pass the semester test.
Learning Outcomes
Knowledge
1.Upon completion of the course, the students will be able to: 1. Correctly use terms of laser physics. 2. Discuss the differences between continuous and pulsed laser systems, and the uses of both. 3. Describe the basics of laser safety. 4. Understand how the design of a laser affects its output characteristics. 5. Assess the properties of laser systems based on a knowledge of their design. 6. Describe the role of lasers in medicine, their applications in diagnostic and therapeutic processes.
Skills
1.Students will be able to use the physical principles in modern medical laser equipment for further studies. They will be able to recognise the more frequent use of laser types and safety classes.
Competences
1.Upon completion of the study course students will be able to evaluate the activity of the laser, its physical structure and its effect on the human body, and to justify the use of lasers in medicine. By the end of the study course the students will be able to apply the principles of the effective use of medical lasers and knowledge of risks.
