Title:
METHOD AND SYSTEM FOR GENERATING COMPOUND ULTRASOUND IMAGE
Document Type and Number:
WIPO Patent Application WO2002047533
Kind Code:
A3
Abstract:
An ultrasound system 100 that generates compound images from component frames having decorrelated speckle patterns. Successive sets of distinct, speckle-affecting parameters are used to generate successive component frames for compounding, and are selected such that the successive component frames have decorrelated speckle patterns. The speckle-affecting parameters that are changed from frame to frame may be selected from a wide variety of parameters, including transmit beamformer 104 parameters, receive beamformer 106 parameters, and demodulator 108 parameters. According to a preferred embodiment, the successive sets of speckle-affecting parameters differ from each other by at least two speckle-affecting parameters. The amount by which each of the multiple speckle-affecting parameters is changed is less than a decorrelation threshold for that parameter, that is, by less than the amount that speckle-affecting parameter alone would be required to change in order to yield decorrelated speckle patterns if no other parameters were changed.
