Abstract
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.
