Arm Phantom Set
…Doppler spectra are measured for the flow through arteries and veins with both a pulsing flow (like a heart beat) and continuous flow, allowing sounds typical of Doppler sonography to be heard. One particularly interesting feature is the possibility of observing the change in the spectra and the Doppler…

Pair of Reflection Blocks with Delay Line
…attenuation. A 4 MHz transducer (U10017) is especially suitable for such measurements. An echo pattern comprising at least 3 echoes is recorded, and the spectra of the individual echoes analyzed. The result of the analysis is a shift in the average frequency toward lower frequencies, due to a stronger attenuation…
