    摘要: A helix antenna structure includes loop antennas and a multilayered printed circuit board including printed circuit board layers. Each printed circuit board layer includes a peripheral loop antenna and each adjacent two loop antennas are electrically connected by a connection bridge functioning as a monopole antenna. A selected printed circuit board layer physically and electrically accommodates a transmitter inside ‘its’ peripheral loop antenna, and it further includes a first antenna feeding line which is connected to the loop antenna that is disposed on the selected printed circuit board layer and electrically connectable to a first output terminal of the transmitter. A second antenna feeding line is disposed on another printed circuit board layer and electrically connected to its loop antenna and connectable to another output terminal of the transmitter. The two antenna feeding lines lie in a plane perpendicular to an axis of the printed circuit board after its folding.

    摘要: Systems and methods for detecting an anomaly in an image from a set of images captured in vivo by an in-vivo imaging system may include, for each pixel of the image, associating the pixel with a color histogram value from a color histogram database; determining, for each pixel, whether the color histogram value associated with the pixel exceeds a histogram value threshold; assigning a pixel status to each pixel indicating whether the pixel is anomalous or normal; identifying one or more groups of adjacent anomalous pixels, the one or more groups of adjacent anomalous pixels each having a pixel size that exceeds a pixel size threshold; generating, using at least the one or more groups of adjacent anomalous pixels, a binary mask for the image; and determining an image anomaly score for the image based at least in part on the binary mask.

    摘要: A system and method for detecting the position of an in-vivo device based on external light: the system may include an in-vivo device configured for being introduced into a body and having at least one sensor configured for sensing light; and an ex-vivo module including at least one illumination source configured for emitting an indication light towards said body; the indication light is configured for being sensed by the at least one sensor.

    摘要: A system, method and virtual tool for size estimation of in-vivo objects includes receiving and displaying a two-dimensional image of in-vivo objects obtained by in-vivo imaging device; receiving indication of a selected area representing a point of interest from the user via a user input device; estimating depth of a plurality of image pixels around the selected area; calculating three-dimensional coordinates representation of the plurality of image points, based on the estimated depths; casting a virtual tool of a known size onto the three-dimensional representation; and projecting the virtual tool onto the two-dimensional image to create a cursor having a two-dimensional shape on the displayed image.
