Safety of Diagnostic Ultrasound No. 6. The Safety of Pulsed Doppler Ultrasound

Abstract

Kazuo Maeda*

There are two pulsed Doppler ultrasound including continuous wave (CW) Doppler and pulsed Doppler, where the safety is discussed in the pulsed Doppler, because of its higher ultrasound intensity, due to longer pulse and higher pulse repetition frequency than simple B-mode ultrasound, and obstetrical setting of ultrasound devices determines the thermal and mechanical indices below one in pulsed Doppler. Ultrasound user is responsible to ultrasound safety, where the user lowers the ultrasound thermal and mechanical indices below one, when indices are higher than one. The use of pulsed Doppler in the first trimester is regulated by ISUOG committee.
