2. Basic NMR experiments - excitation, FID signal, spin echo, gradient echo, acquistion parameter - repetition time (TR), TE time, image weighting by relaxation times T1 and T2.
3. NMR hardware - main magnet, permanent and superconducting magnet, active and passive shimming, homogenity of main field B0, gradient coils, RF coils for different applications.
4. NMR imaging - from proton to image, slice excitation/selection, k-space, frequency and phase encoding, image reconstruction.
5. Pulse sequences - spin echo, gradient echo, inversion recovery, saturation recovery, fast sequences - multi-shot, multi-band, EPI.
6. Special applications - using of gadolinium based contrast agent, functional magnetic resonance imaging (fMRI), arterial spin labelling (ASL), perfusion parameters mapping - DCE, DSC, spectroscopy, diffusion-weighted imaging (dMRI).
7. Using of ultrasound in medical imaging - wave equation, ultrasound wave described as change of pressure in time and spate, acoustic impedance, reflection. Magnetostriction and piezoelectric crystals, transducers.
8. Ultrasound system - development chart, ultrasound transducer types - linear, convex, phase-array. Different types of contstruction, hardware and software focusing. TGC amplifier, data conversion, imaging. Basic ultrasound modes - A mode, B mode, 3D imaging, TM mode, artifacts and image quality assessment.
9. Advanced ultrasound techniques - Doppler effect, coninutous Doppler, pulse-wave Doppler, color and power Doppler, ultrasound contrast agents, perfusion imaging - overview of techniques for qualitative and quantitative assessment of perfusion parameters. Elastography, ultrasound tomography, photoacoustic imaging.
10. Endocsopy - principles of visible light endoscopy, types of constructions - rigid, endoscopic mirror, flexible (fibroscopy), capsule endoscopy, ultrasound in endoscopy (transesofageal echocardiography, others). Intravascular ultrasound (IVUS).
11. Thermography (infrared cameras) - physical principles of thermography, noctovision, Planck emission law, Wien law, Stefan-Boltzman law, emissivity, absorptivity, absolute black body, illustration of inrared radiation detection.
