Appl. No.:

10/372423

International Classification:

A61B 8/00

US Classification:

600446, 600437, 600445, 600459

Abstract:

Methods and systems for measuring transducer movement are provided. For example, free-hand scanning for three-dimensional imaging is provided. An optical sensor within the transducer measures motion along the skin surface similar to measuring movement of a personal computer mouse with an optical sensor. Alternatively or additionally, the transducer is tilted at an angle other than perpendicular to the skin surface generally towards or away from the direction in which the transducer is translated. The transducer is then translated while maintaining the angle. Motion to or from the transducer is measured, and a component of the motion measured while the transducer is maintained at an angle is parallel to the direction of translation. The component of motion is angle corrected and used to determine a distance of travel.

International Classification:

A61B 802

US Classification:

600454

Abstract:

An ultrasound imaging system produces three-dimensional tissue/flow images by first computing a plurality of separate two-dimensional tissue images and two-dimensional flow images. Separate tissue and flow volumes are created by applying the tissue and flow images to a three-dimensional construction algorithm. Each of the separate tissue and flow volumes is analyzed using a three-dimensional rendering algorithm to produce a rendered tissue and flow image. The separately rendered tissue and flow images are combined to produce the combined tissue/flow image. In addition, the present invention provides visual cues that allow a user to create more even scans. The invention also includes a method for correcting for probe movement. The invention also produces an image that is calculated from the partial volume data as it is being created to give a user feedback on the quality of the image they are producing. Finally, the invention compensates for variations in the cardiac cycle when selecting data to be used in creating a flow volume.

Abstract:

Systems and methods for estimating attitude using double differenced GPS carrier phase measurements are provided. An exemplary computer-implemented method includes obtaining, by one or more computing devices, an initial candidate attitude. The method includes determining, by the one or more computing devices, a plurality of expected double differenced carrier phase values based on the initial candidate attitude. The method includes inputting, by the one or more computing devices, the plurality of expected double differenced carrier phase values into a cost function. The cost function respectively compares the plurality of expected double differenced carrier phase values to a plurality of measured double differenced carrier phase values. The method includes minimizing, by the one or more computing devices, the cost function. The method includes selecting, by the one or more computing devices, a final candidate attitude associated with the minimized cost function as the attitude of the device.
