Electromagnetic radiation and relationship to the medical imaging systems. Imaging theory fundamentals. 2D Fourier transform and related applications. Transfer properties of

imaging systems. Optical imaging systems. Television (TV)

imaging systems (including videoendoscopy and capsule imaging). Fundamentals of image processing. Imaging systems using infrared radiotion (termovision systems). X-ray imaging systems. X-ray TV medical imaging systems. Nuclear medical imaging systems. Ultrasound medical imaging systems Doppler systems. Computed tomography (basic idea, schematic system arrangement, basic physical principle, development generation, basic principles of reconstruction) Magnetic resonance imaging. Positron emission tomography (PET) and Single photon emission computed tomography (SPECT) Specialized medical imaging systems. Lectures and laboratory exercises offer to students view on the medical image data formation, on the sensing and scanning principles, on the digitization and processing, on the functional principle and image sensing devices as well. There are very important mutual relationships, which are important from the point of view of subject and study branch interdisciplinarity.

Syllabus of tutorials:

no excercises

Study Objective:

To give the students information about physical-technical

principles of conventional image formation in imaging

systems and tomographical imaging systems. The idea is to

understand limiting principles and parameters of these

imaging systems. Based on this understanding, the student

will be able to decide whether or not medical doctors

requirements are satisfied.
