Learning outcomes of the course unit The course is a follow-up to the course Radiological Technics - Diagnostic Radiology and the student gains a deeper overview of X-ray diagnostics including CT in practice. Furthermore, they will be acquainted in more detail with parameters for image quality and image processing and also with communication protocols in radiology. Last but not least, they will learn how to proceed in case of exposure to a pregnant patient and also how machine learning is used in radiology.



Syllabus of lectures:

1. Types of X-ray tubes and their characteristics, technological advances in X-ray systems

2. Parameters characterizing image quality - SNR, MTF, DQE, QDE, NEQ, NPS, NNPS; Exposure parameters for skiagraphy - AEC, exposure without AEC, exposure index and its use

3. Exposure parameters and dosimetry in skiascopic guided procedures (including interventional) - cumulative doses (PKA, dose in IRP), dose estimation on skin, exposure parameters (kV, mA, ms, filtration, focus) - allowed range and quality impact image and dose, ADRC, various display modes (fluoroscopy, acquisition - native, DSA, roadmapping, image overlay, image fusion)

4. Exposure parameters and dosimetry in CT - parameters affecting image quality (kV, mA, rotation time, reference image quality, centration), current modulation (angular, longitudinal, organ) and voltage, CTDI, SSDE, DLP, organ doses , effective doses

5. Optimization of CT protocols for various applications - sequential vs. helical, native vs. contrast image; angiography, types of reconstructions (multiplanar, MIP, VRT ...); CT perfusion, CT in cardiology, factors affecting spatial resolution, contrast resolution and time resolution

6. Advanced techniques - CT intervention, dual energy and spectral CT (virtual non-contrast image, monoenergetic image), cone-beam CT, O-arm, digital tomosynthesis, imaging using phase contrast

7. Data processing, displaying and archiving, communication protocols in healthcare - DICOM, HL7, MPPS, content and usage of DICOM protocols, teleradiology

8. Irradiation in pregnancy - radiobiology, dose estimation for various modalities, radiation protection of pregnant patients with radiation

9. Radiation protection of patients and staff; Benefit Score risks in X-ray diagnostics - screening, low dose effect, epidemiological studies

10. Legislative requirements and quality assurance - GDR, DRC, clinical audits, QC (PZ, ZDS, ZPS), dose management, standards

11. Machine learning and its application in radiology

12. Image quality from the radiologist's point of view - skiagraphy, fluoroscopy, CT
