Abstract: A method for measuring motion from biological imaging data including collecting non-carrier data images; patterning the non-carrier data images with synthetic carrier properties; and processing the patterned non-carrier data images with a carrier based motion tracking technique to generate images representing motion measurements. The method preferably converts images lacking a carrier signal to ones with a synthetic carrier signal such that highly accurate and robust speckle tracking can be achieved.
Abstract: A method and system for acquiring and analyzing multiple image data loops comprising: receiving a set of ultrasound data, characterizing a tissue, collected over a first collection loop and a second collection loop; determining a tissue parameter distribution within the tissue based on the set of ultrasound data and multi-dimension speckle tracking; receiving identification of at least one region of interest represented in the set of ultrasound data in the first collection loop and the second collection loop; measuring a comparative characteristic, in the region of interest, between the first collection loop and the second collection loop; and rendering at least one of the comparative characteristic and the tissue parameter distribution. The system comprises a processor, an analysis engine, and a user interface, and may further comprise an ultrasound scanner. The system is preferably configured to perform the method.

Abstract: In a first preferred embodiment, the invention includes a method of tracking displacements between ultrasound images by calculating a coarse displacement estimate, and calculating a fine displacement estimate using images and coarse displacement estimate. In a second preferred embodiment, the invention includes a method of calculating a coarse displacement estimate from images by reducing the resolution of the images, correlating the reduced resolution images, and calculating the location of the peak of the correlation function. In a third preferred embodiment, the invention includes a method of calculating a finer displacement estimate from images by using a coarse displacement estimate with correlation processing of the images and calculating the location of the peak value of the correlation function.
