Synopsis:

The history of television technology. Overview of television technology. Viewing scenes (linear transformations in 3D space, viewing lens as colineation, screenings). Picture information (light, photometry, colorimetry, light sources, vision, quantitative description of the image information, the image spectrum). TV system. Physical limitations resolution and correlation characteristics of the image and characteristics of the system. Resolution of the TV system. Creating video signal. Nonstandard TV shooting. Black and white versus color TV system. Applications TV imaging systems in medicine. Physical quantities describing radiation and light. Physical laws of thermal radiator. Principle of operation of the IR system and its diagnostic significance. Specifics of thermography imaging systems. Block diagram. Description of individual blocks and circuits. History endoscopes. Types of endoscopes. Fundamentals of the theory and practice of optical fibers. Flexible fiberscopes. A flexible video endoscope. Special flexible video endoscope (enteroskopy). Light sources for flexible endoscopes. Image sensors used for endoscopes. Image processors. Monitors for video endoscope. Endoscopic - ultrasound systems. Sterilization device. Automatic „washing machine“ for endoscopes. Standard procedures. Possible problems. Imaging capsule. Principle. Block arrangement. Wireless transmission and data processing. Possible complications.

Requirements:

Assessment requirements are the following:

Mandatory attendance at all exercises. Absence is possible only due to serious reasons (substantiated). Set of small tests based on the annoncement. It will be announced in advance as a requirement of knowledge on exercise. There is part of the assessment as written test on 9 issues where the combined option ABC-type answers (always one correct) - 1 point option when you need to respond in writing - 5 points (important issues). There is required to do homeworks as well. Boundary passing the test is 50% within the ECTS grading scale.
