In this tutorial, we demonstrate physical principles, which are relevant in the practical routine in ultrasound diagnostics. Beside the interaction of ultrasound with the tissue, basics of the effects of frequency, propagation velocity, pulse repetition frequency, scattering and beam formation are illustrated. Practical examples and typical artifacts are discussed as well as influence on the machine settings (Beam focus, TI, MI, focus) on the quality of your analysis. The effects of data post processing (e.g. tissue harmonic imaging, rendering etc) will be demonstrated. Finally, the correct disinfection in clinical routine is presented.


Key words: vascular ultrasound, basics in physics.
