Paper Abstract

In this paper we present a method to visualize the pressure field of an ultrasound beam in a single shot of the CCD and to image the shear wave propagation based on acousto-optic laser speckle contrast analysis. The contrast images show features in the near field, far field and central region of the ultrasound beam and the pressure profile fits with that measured with a hydrophone. The shear wave propagation was acquired by changing the imaging delay time after the ultrasound burst. This method can be used to study the shear wave properties of common tissue phantoms to guide experiments on tissue.
