- Grading of the course requires grading of the following courses:
- Physics II (17ABBFY2)
- Department of Biomedical Technology
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.
Physics from the point of view of the interaction of radiation with matter, particle physics, optics, and from this follows the requirements for a prerequisite for registration of the course. The theory of systems it is also suitable for.
Assessment and exam requirements:
Participation is mandatory on all exercises. Non-participation is possible for serious reasons only (to be substantiated).
At the end of each lesson (exercise in PC lab), the fulfilled assignment must be given to the teacher for the current week.
It is not possible to take the exam without obtaining the credit and enrolling it in the CTU IS KOS.
The exam is based on the written test and this one consists of a two variants of questions. The so called MCQ, i.e. ABC answer variant (one answer is correct only) with 1 point, i.e. 0 or 1 point. Marking multiple answers means 0 points, no answer means 0 points, bad answer means zero points. The second variant of answers includes the so called open questions (important questions), i.e. 5 points (0 to 5 points). Correct answer can be assessed from 0 to 5 points based on quality of the answer. The whole test consists of a total of 36 questions, of which 20 MCQ (abc) for 1 point and 16 open questions for 5 points. There is required minimum 50 points and there is available max. 100 points. Assessment of the test according to ECTS table (classification grades) is given in the CTU Study and examination code. The total time reserved for the test is 120 minutes. After the test, this one is corrected and there is possible to improve the whole test result if the test result is at the grade boundaries (typically max. by -2 points).

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.
