Description:

The course deals with advanced imaging techniques, which are used mainly for diagnostic purposes in clinical practice. Emphasis will be placed on the technical principle of the devices, on the possibilities and limitations of individual modalities. The issue of image reconstruction in tomographic imaging systems will also be addressed.

1. Overview and classification of imaging modalities in clinical practice. Data formats for imaging modalities
2. Fundamental methods of image processing
3. Theory of linear 2D systems, 2D Fourier transform
4. Ultrasound imaging systems (ultrasound)
5. Doppler ultrasound imaging systems
6 Computed tomography - CT
7. CT angiography
8. Imaging methods in nuclear medicine
9. Reconstruction methods of tomographic image
10. Magnetic resonance (MR) - technical principle
11. Pulse sequences and protocols for MR
12. Sensing of physiological quantities during MR examination
13. Functional examination by magnetic resonance
