A Computer Model for Speckle in Ultrasound Images: Theory and Application

  • R. J. Dickinson
Part of the Acoustical Imaging book series (ACIM, volume 10)


The ultrasonic B-scan of regions of parenchymal tissue has a number of properties which are similar to laser speckle, and distinguish it from imaging techniques using incoherent radiation such as radiography. The special properties of the image mean that conventional techniques of image processing and analysis are inadequate, and to develop more appropriate techniques and relationship between the final image and the tissue properties and the ultrasonic field must be understood in more detail. This paper describes the use of a theoretical model and a computer simulation to examine this relationship, and its possible application to the evaluation of image processing routines.
