    摘要： A switching circuit includes a first switch and a second switch respectively connecting a first terminal and a second terminal of an electrical coil to a positive terminal of a voltage source, a third switch and a fourth switch respectively connecting the first terminal and the second terminal of the electrical coil to a negative terminal of the voltage source, and a controller to control the switching circuit in a current control mode to alternate a voltage polarity of the voltage source to thereby control a magnitude and direction of the electrical current of the electrical coil, and to control the switching circuit in a current hold mode to disconnect the electrical coil from the voltage source and to short-circuit the electrical coil to maintain the magnitude and direction of the electrical current at the transition time when the switching circuit switched to the current hold mode.

    摘要： An optimization unit controls electrical currents of a set of electromagnets to generate a wanted maneuvering magnetic field pattern (MMP) for moving an in-vivo device in the GI system. The optimization unit may calculate a magnetic force and a magnetic field to maneuver the in-vivo device from a current location and/or orientation to a new location and/or orientation. The optimization unit may solve a magnetic force optimization problem with respect to the magnetic force in order to determine electrical currents suitable for generating the wanted MMP. The optimization unit may additionally or alternatively solve a minimum electrical power optimization problem with respect to the electrical power to be consumed by the electromagnets in order to recalculate or adjust the electrical currents. The optimization unit may solve one or more of the optimization problems while complying with a set of constraints associated with or derived from each type of optimization objective.

    摘要： An in-vivo imaging system and method to automatically detect a pathology frame sequence in an image stream captured in vivo. An image stream comprising a plurality of image frames captured in vivo may be received, and a pathology score for at least a portion of the image frames is received. A seed frame which includes at least one pathology candidate may be selected, and the position of the pathology candidate in the seed frame may be determined. A sequence of frames adjacent to the seed frame is defined comprising frames that depict the pathology candidate, and a pathology sequence score is calculated based on the sequence, the pathology sequence score correlating to the probability that the sequence of frames adjacent to the seed frame includes a pathology. If the pathology sequence score is within a range, a display method may be adapted, or the pathology score may be changed based.

    摘要： A system and method for detecting a transition in a stream of images of a gastrointestinal (GI) tract may include selecting images from an in-vivo image stream; calculating a segment score for each selected image indicating in which segment of the GI tract the image was captured; applying a smoothing function on the scores; detecting a global step in the smoothed segment score signal indicating a substantial change in a parameter calculated based on segment score signal values of the segment score signal values; detecting a local step indicating a substantial change in a parameter calculated based on segment score signal values of a predetermined interval of the of the segment score signal values; combining the local step and the global step; and determining a point of transition in the stream from one anatomical segment to another, the point of transition correlating to the combined step.
