Abstract: A method of estimating lung motion (e.g., local lung motion and local lung ventilation) includes collecting a time series of ultrasound images of a lung surface, the time series including a plurality of frames, identifying a lung surface in one of the plurality of frames, and subsetting each of the plurality of frames into at least one sub-image. The method further includes applying a high pass temporal filter and a spatial filter. The method still further includes calculating inter-frame motion data from complex data sets associated with one or more pairs of temporally successive frames. In a further method, lung surface longitudinal strain is also calculated.

Abstract: 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.

Abstract: A device for 3-D imaging of the oral cavity for purposes of implant positioning, and in particular, a dental ultrasound scanner connected to a registration device that provides coordinates for realigning ultrasound images. The ultrasound scanner includes transducers having frequencies of 18 megahertz or higher and wavelengths of 80 microns or less. The reference device may be used as a surgical guide or a separate surgical guide may be created.

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.
