A method of estimating lung motion includes collecting multiple ultrasound image data captured at one or more locations of a sample region of tissue. The method further includes comparing the multiple ultrasound image data and determining temporal correlation coefficients between each of the multiple ultrasound image data. The method still further includes displaying an image of the sample region of the tissue with the temporal correlation coefficients identified, thereby indicating lung motion. In further methods, the determined temporal correlation coefficients are used to determine an amount of decorrelation, which can be used to determine strain of the tissue over the sample region and to calculate lung displacements and lung shape changes representing ventilation.

Ultrasound speckle decorrelation estimation of lung motion and ventilation

An imaging assembly includes a compression system configured to receive and compress an object to be imaged. The compression system includes a first compression paddle and a second compression paddle. The imaging assembly further includes an ultrasound system including a first ultrasound probe coupled to the first compression paddle. The first ultrasound probe is configured to acquire a first portion of the ultrasound image information of the object. The ultrasound system also includes a second ultrasound probe coupled to the second compression paddle. The second ultrasound probe is configured to acquire a second portion of the ultrasound image information of the object.

System and method for breast imaging

An ultrasound-based system determines dynamic strain measurements over a surface using ultrasound speckle analysis that allows for accurate measurement of surface area displacement. The system additionally determines an approximate displacement along a third axis, the z-axis. From these, an estimation of a local volume change is determined. In this way, a volume change can be determined for the lung or any other region of interest.
