Attenuation : Beam divergence
Beam divergence As an ultrasound beam propagates through a medium, it’s wavefront diverges. This effect is not related to attenuation properties of the medium, but is due to diffraction effects An ultrasound diverges In the far field of a non focussed transducer distal to the focal zone of a focussed transducer after reflection from a Read more about Attenuation : Beam divergence[…]
