Fantom pro diagnostický ultrazvuk a dopplerovské vyšetření

Summary

In the article the main physical principals of creation, propagation and reflection of ultrasonic waves were described. The diagnostic methods based on Doppler’s effect were explained. The two phantoms for education were created. The first phantom contained echogenic and cystic structures of various shapes and sizes, from materials with different acoustic properties. In the second phantom the branched system of tubes that carry fluid simulating blood flow in the body was placed. Students in these phantoms acquire basic skills with an ultrasonic diagnostic device, such as working in various display modes, identifying tissue structures, measuring areas and distances displayed in sections, measuring the speed and volume flow using the Doppler effect.
