  • Patent number: 10736492
    Abstract: An in-vivo device may be propelled in the gastrointestinal tract by a magnetic force such that the direction of the magnetic force applied to the in-vivo device follows, or is continually adapted to, the instantaneous spatial orientation of the in-vivo device. As the in-vivo device changes orientation in the gastrointestinal tract by the wall of the gastrointestinal tract, so does the magnetic force, to follow suit.

  • Patent number: 10405734
    Abstract: Systems and methods for displaying an image stream captured by an in vivo imaging device are presented. A method comprises receiving a stream of image frames captured by the in vivo device, each frame comprising a plurality of pixels. A summarized image presentation comprising summarized data elements may be generated, each summarized data element corresponding to at least one frame from the image stream. Summarized data elements are generated by ordering pixels of one or more image frames according to a first sorting parameter, sampling the ordered pixels according to a predetermined sampling scheme to acquire a subset of ordered pixels; and combining or appending sampled pixels to form a summarized data element. The summarized data elements are combined to form a summarized image presentation.

  • Patent number: 10206588
    Abstract: Devices and a system for detection of blood within in-vivo fluids are provided. A device comprises a housing that includes a gap. The gap has at least one opening through which in-vivo fluids may enter and/or exit the gap. The device further comprises an illumination source for illuminating the in-vivo fluids in the gap, a light detector for detecting light which passes through the in-vivo fluids in the gap, and flexible fins disposed on the housing in the vicinity of the gap's opening for covering the opening when the fins are folded and for pumping fluids into and out of the opening by repeated closure and opening of the opening by the fins, due to repeated peristaltic waves. This pumping effect may lead to continuous flow of fluids into and out of the opening and thus into and out of the gap of the device.

  • Patent number: 10204411
    Abstract: A system and method for segmenting an image stream to a plurality of segments is provided. A processing unit may be configured to calculate a set of pixel-based properties for frames of an image stream, and detect segments of constant mean values in the sets of pixel-based properties. The segments of constant mean values are detected by using a window method that determines possible partition points of the window, and calculating a difference between mean values of the sets of pixel-based properties for each sub-window of frames. Points of change may be identified in the calculated difference between mean values of the sets of pixel-based properties. A display unit may display a summarized representation of the image stream, wherein the summarized representation includes a plurality of segments, each segment corresponding to a segment of constant mean values in the sets of pixel-based properties.

  • Publication number: 20190029504
    Abstract: Methods for capturing and transmitting images by an in-vivo device comprise operating a pixel array in a superpixel readout mode to capture probe image, for example, according to a time interval. Concurrently to capturing of each probe image, the probe image is evaluated alone or in conjunction with other probe image(s), and if it is determined that no event of interest is detected by the last probe image, or by the last few probe images, the pixel array is operated in the superpixel readout mode and a subsequent probe image is captured. However, if it is determined that the last probe image, or the last few probe images, detected an event of interest, the pixel array is operated in a single pixel readout mode and a single normal image, or a series of normal image, is captured and transmitted, for example, to an external receiver.

  • Patent number: 10102334
    Abstract: A system and method for automatically navigating an in vivo imaging capsule in a body lumen. The system comprises an imaging capsule including an imager, optional pressure sensor for producing data of forces acting on the imaging capsule in vivo, and a transmitter to transmit image, positioning and pressure data from the capsule to an external unit. A positioning system for providing current position data of the capsule in vivo may be included in the capsule and/or external to it. External magnets may generate a magnetic field to scan a body lumen by causing a predetermined motion pattern of the imaging capsule within a region proximate to its current position, and generate a driving force to propel the imaging capsule according to a calculated target direction vector. A processor may calculate a target direction vector for propelling the imaging capsule based, on unique patterns identifiable in one or more images.
