Synopsis:

History of television systems. Overview of television systems. Scene representation (linear transformation in 3D space, lens representation as collineation, projection). Image information (light, photometry, colorimetry, light sources, vision, quantitative description of image information, image spectrum). Television system. Physical limitations of resolution and correlation of image characteristics and system characteristics. TV system resolution. Creating video signal. Non-standard TV shooting. Black and white versus color TV system. Application of TV imaging systems in medicine. Physical quantities describing radiation and light. Physical laws for heat emitter. Principle of the operation of infrared imaging system and its diagnostic importance. Specifics of thermal imaging systems. Block diagram. Description of individual blocks and circuits. History of endoscopes. Types of endoscopes. Fundamentals of theory and practice of optical fibers. Flexible fibroscopes. Flexible video endoscopes. Light sources for flexible endoscopes. Image sensors used for endoscopes. Image processors. Monitors for video endoscopes. Endosonographic systems. Sterilization equipment. Automatic disinfectors for endoscopes. Standard procedures. Possible problems. Capsule imaging. Principle. Block arrangement. Wireless transmission and data processing. Possible complications.

Requirements:

Compulsory attendance at all exercises. The absence is possible only for serious reasons (documented). Completion of three tests for individual parts, which are 3 (TV, IR and endoscopic imaging systems) from the issues discussed within the lecture, respectively. has been announced in advance as a requirement of knowledge for exercise. Each test contains 3 open questions for 5 points (3x5 = 15 points) and 5 ABC questions (always correct at least one answer) for 1 point (5x1 = 5 points). Total possible maximum number of points gained from all tests is equal 60. 50 % points, i.e. 30 points from all tests there is required. There aren´t required minimum points for individual tests.
