Grading of the course requires grading of the following courses:
Physics II (17ABBFY2)
Lecturer:
Jiří Hozman (guarantor), Martin Rožánek
Tutor:
Martin Rožánek, Petr Volf
Supervisor:
Department of Biomedical Technology
Synopsis:

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.

Requirements:

Presence within the all exercises is mandatory. During the exercises are processed Matlab tasks that are required within the assessment with respect to the supervisor instructions. Assessment is required for exam and before the exam.

Exam is based on the written test, where are applied MCQs and open questions (only one answer is right in all cases). Right answer 1 or 5 pts., selection of more answers, i.e. 0 pts., no answer, i.e. 0 pts., bad answer, i.e. 0 pts., min. 50 pts, max. 100 pts, ECTS table applied, 52 questions, i.e. 40 MCQs with 1 pt., 12 open questions with 5 pts., 90 minutes.

11. Practical exercises - X-ray and ultrasound medical image systems (students will be divided into two groups and after the 40 minutes these groups will changed)

12. Practical exercises - infrared (thermovision) and endoscopy medical image systems (students will be divided into two groups and after the 40 minutes these groups will changed)

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.
