 Ultrasounds should be used when medically indicated. (They shouldn’t be used in the first trimester in a low-risk pregnancy.)

 The operator should have a high level of skill and experience and should only use minimum intensity settings.

 A session should last no more than 3 minutes (5 minutes maximum)

 Avoid non-medical 3D ultrasounds. They carry a potentially higher risk to baby due to the higher acoustic output required for high-definition images.
