  • Patent number: 9639765
    Abstract: A method of determining whether a biometric object is part of a live individual is described. In one such method, image information is acquired from the biometric object by using a sensor, such as an ultrasonic sensor. The image information may be analyzed in at least two analysis stages. One of the analysis stages may be a temporal analysis stage that analyzes changes in the image information obtained during a time period throughout which the biometric object was continuously available to the sensor. For example, a dead/alive stage may analyze differences between image information taken at two different times in order to identify changes from one time to the next. Other stages may focus on aspects of a particular image information set, rather than seeking to assess changes over time. These other stages seek to determine whether an image information set exhibits characteristics similar to those of a live biometric object.

The grip is configured to support an operator's palm, such as a majority of the operator's palm, such that force applied to the ultrasonic inspection apparatus by the operator is transferred via the grip to the ultrasonic sensor. The non-destructive inspection system may also include a computer in communication with the non-destructive inspection apparatus to receive information relating to the return signals received by the ultrasonic sensor.

    Abstract: Ultrasound apparatus or techniques can include obtaining reflected ultrasound echo information, which can be used to construct a two-dimensional or three-dimensional representation of an at least approximately specular reflected target, such as bone. In an example, echo information can be obtained from spatially-overlapping tissue regions, such as using one or more of an array of ultrasonic transducers, or mechanically-scanning one or more ultrasonic transducers. In an example, one or more of a deformable housing or a deformable coupling pad can be used, such as to couple ultrasonic energy between one or more transducers and a tissue region.

  • Publication number: 20150087979
    Abstract: A method and system acquiring, processing and displaying breast ultrasound images in a way that makes breast ultrasound screening more practical and thus more widely used, and reduces the occurrence of missing cancers in screening and diagnosis, using automated scanning of chestwardly compressed breasts with ultrasound. Enhanced, whole-breast navigator overview images are produced from scanning breasts with ultrasound that emphasize abnormalities in the breast while excluding obscuring influences of non-breast structures, particularly those external to the breast such as ribs and chest wall, and differentiating between likely malignant and likely benign abnormalities and otherwise enhancing the navigator overview image and other images, thereby reducing the time to read, screen, and/or diagnose to practical time limits and also reduce screening or diagnostic errors.

  • Patent number: 8956299
    Abstract: A method for generating an ultrasound image includes receiving an image frame having consecutive ultrasound scan lines obtained using a rotating ultrasound imaging arrangement and determining first and second cross-correlation values for a plurality of the scan lines. For each individual scan line, the first cross-correlation value includes a cross-correlation coefficient between a first subframe of consecutive scan lines including the individual scan line and a second subframe of scan lines shifted from the first subframe by a first integer value. The second correlation value includes a cross-correlation coefficient between the first subframe and a third subframe of scan lines shifted from the first subframe by a second integer value. The method further includes evaluating, individually for multiple scan lines, whether that scan line exhibits non-uniform rotation distortion using at least one of the first and second cross-correlation values. A correction for non-uniform rotation distortion is applied.
