1. A method for measuring ultrasound image motion for biomedical applications comprising:

  • an ultrasound processor is programmed to perform;

    acquiring ultrasound images without carrier properties;

    applying at least one complex filter to the ultrasound images to generate a synthetic speckle pattern, the at least one complex filter comprising at least one unique pattern parameter identifying an aspect of the ultrasound images to which the at least one complex filter will be applied wherein the at least one unique pattern parameter is at least one of a center frequency parameter and a bandwidth parameter;

    deriving artificial carrier properties for the images from the synthetic speckle pattern;

    producing speckle tracking data with a speckle tracking algorithm operating on the images and the artificial carrier properties;

    wherein the producing speckle tracking data includes;

    producing a first set of speckle tracking data according to a first set of speckle tracking parameters to generate a first stage result; and

    producing at least a second set of speckle tracking data according to a second set of speckle tracking parameters to generate a second stage result;

    wherein producing at least a second set of speckle tracking data comprises using the first stage resultextracting motion tracking parameters from the speckle tracking data; and

    creating images representing motions based on the motion parameters.
