PARAMETER INITIALISATION FOR THREE-DIMENSIONAL ULTRASOUND DECONVOLUTION

Dec 2009

Conventional beamforming used in pulse-echo ultrasound images results in an inherent blurring. This blurring limits the resolution, and hence the utility, of pulse-echo ultrasound in clinical applications. Ng et al. developed an expectation-maximisation algorithm to enhance blurred, two-dimensional RF ultrasound images. It is important that the algorithm is intialised well in order that convergence is rapid. We present here a methodology, with rationale, for estimating the initialisation parameters for the deconvolution algorithm described by Ng et al.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
