How safe is ultrasonic Doppler velocimetry?

Ultrasonic Doppler velocimetry is a safe technique when applied correctly. The mean ultrasonic power is low, in the order of few milliwatts. The maximum instantaneous power, which is in the order of tens of watts during the emission of the burst, is most of the time not enough to generate cavitation. The only noticed effect is a small local increase of the temperature of the medium under investigation.
