Supervisor:
Department of Biomedical Technology
Synopsis:

Electromagnetic radiation spectrum and relationship to the modalities of medical diagnostic imaging systems. Fundamentals of imaging theory. Application of 2D FT. Transmission properties of imaging systems. Optical imaging systems including microscopic. Television imaging systems (including video endoscopic imaging systems). Basic digital image pre-processing methods. Infrared imaging systems (thermal imaging/IR imaging systems). X-ray imaging systems. Gamma imaging systems. Lectures and especially the laboratory exercises provide students with an overview of the principles of image formation in medicine for conventional imaging systems and methods. There are described methods for image data sensing, digitization and subsequent processing and principles of function and properties of sensing image devices in context, which is especially relevant from the interdisciplinary point of view of the whole course and study specialization.

Knowledge, skills and competences:

The student is able to explain the basic physical principle of the given modalities and knows its layout including the principle of image formation.

The student is able to assess, on the basis of standard definition of technical parameters that imaging system meets the physician requirements for selected modality. Such knowledge is a prerequisite to the correct process technology selection and application of the modalities as well as the minimum necessary to ensure the required quality of the resulting image data.

Requirements:

Course requirement:

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).

Study Objective:

The aim of the course is to acquaint students with general fundamentals of imaging process theory, sensing methods, evaluation and processing of image information, image signal properties, principles of image formation, structure and general quantitative assessment of the quality of conventional imaging modalities used in medicine and the resulting limitations and risks.
