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.

System and method for producing mid-air tactile stimulation

The present disclosure concerns an ultrasound system for providing tactile mid-air haptic feedback. As described herein, various embodiments of the invention can create a precise mid-air tactile sensation in mid-air on a body part of a user through use of an array of ultrasonic emitters. The array produces steerable focal points of ultrasonic energy that provide sufficient radiation pressure to be felt by the skin of the user. Such an implementation allows for multiple points of contact with immersive computing environments in a variety of form factors. This implementation, too, allows for coverage of larger distances and provides for a wider range of interactions thereby allowing a user to extend an appendage into a broader workspace while providing for multiple points of or comprehensive sensation or interaction without sacrificing user comfort with respect to any such interaction.

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.

A mesh storage apparatus comprises a conformal mesh member (14), which is attached to a retraction mechanism (10). Because the mesh member (14) has a point of attachment (20), rather than multiple points spread along one of its sides, the force of the retraction mechanism or another applied force collapses the mesh member along its major diagonal (13) into an elongated form, similar to that of a cable, rope, or strap, allowing for easy storage. It, therefore, takes advantage of the contractility of the mesh openings and the behavioral characteristics of conformal material under tension to store the mesh member (14) in a much more compact manner than with traditional storage apparatus.

An opto-acoustic detector includes a fiber laser having a cavity which includes an optical fiber having an active medium portion doped with a gain material so that the detector may be used in high frequency, high density arrays. The cavity is bounded by a frequency selective reflector and a broadband or frequency selective reflector adapted to be acoustically coupled to a medium supporting ultrasound radiation (i.e. acoustic waves). In one embodiment, the frequency selective reflector is a diffraction grating placed external to the optical fiber. In another embodiment, the frequency selective reflector is a narrowband reflector placed directly in the optical fiber. An acoustic signal enhancing feature which increases sensitivity of the detector is provided by utilizing a reflective membrane having a thickness substantially less than the acoustic wavelength, .lambda., as the broadband optical reflector. The membrane is displaced from a free end of the optical fiber in the cavity and a laser beam exiting therefrom is focused on the membrane with a spot size on the order of the optical fiber core diameter. In this way, the sensing area of the detector is essentially the cross-sectional area of the fiber core which is typically comparable to or less than .lambda..sup.2 even at ultrasound operating frequencies greater than 500 MHz. The reduced element size permits closely spaced optical detectors enabling high density arrays for high frequency imaging.
