Learning outcomes
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.
Form of study
Distance form
Prerequisites and co-requisites
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.
Course content
Physical models in ultrasound diagnostics. Models of biological tissues. Continuous approach. Biological tissue as a homogeneous continuum. Basic concepts of the theory of oscillations. The propagation of sound in matter. The equation of continuity and its physical meaning. Types of biological continuums. Deformations and stresses in the continuum. Viscoelastic continuities of Voigt and Maxwell. Standard viscoelastic continuum. K- and P-continuums. Hereditary elastic continuum. Model of piecewise homogeneous continuum. Equation of motion of biological continuums. Radiation and sound scattering in ultrasound diagnostics. Sound wave emitters. The radiation is continuous and pulsed. Energy flow.

Planned learning activities and teaching methods
Lectures
Assessment methods and criteria
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.
