To know: basic concepts and patterns of biophysics; physical bases and biophysical mechanisms of action of external factors on the biological environment and systems of the human body; opportunities and scope of mastered methods; general physical and biophysical laws that underlie human life; physical bases of diagnostic and physiotherapeutic (therapeutic) ultrasonic methods used in medical equipment. To be able to: analyze the relationship of physical and biological aspects of the functioning of living systems on the basis of physical laws and phenomena; choose appropriate physical research methods to solve specific problems of diagnostic analysis of biosystems; creatively use physical methods to study and diagnose the physical characteristics of biological systems; independently study and use the literature in this discipline, analyze experimental data.

Distance form

To master the discipline requires knowledge gained in the general course of physics, general biology, courses of theoretical mechanics, molecular and quantum physics. In turn, the knowledge, skills and abilities acquired in this course are used in the study of biophysical courses.

Lectures

Semester evaluation: during the lectures students are interviewed orally by answering a certain number of questions. The final grade for the educational component as a whole, the final form of control for which the exam is set, is defined as the sum of grades (points) for all successfully assessed learning outcomes during the semester (grades below the minimum threshold are not added to the final grade) and grades obtained during exam. The form of the exam is to write a written paper followed by an oral interview. The maximum number of points that can be obtained by the student during the exam is 60 points on a 100-point scale. Prerequisite for admission to the exam is the completion of all practical work and writing modular tests. An applicant is not allowed to take the exam if he / she scored less than 20 points during the semester.
