Abstract: A device, system and method for capturing in-vivo images allows for size or distance estimations for objects within the images. A scale may be overlayed on or otherwise added to the images and, based on a comparison between the scale and an image of an object, the size of the object and/or the distance of the object from an imaging device may be estimated or calculated.

Abstract: A device and system for in-vivo imaging with changeable fields of view includes a capsule shaped housing having an external shell that is adapted to be swallowed and passed through a patient due to the housing having no physical connection to the outside. The housing encloses an imaging unit that includes an imager and an illumination source, and a rotatable structure to alter the field of view of the imaging unit. The rotatable structure includes a motor that rotates the imaging unit relative to the and within the external shell. External commands transmitted from outside a patient can control the rotatable structure.

Abstract: A system and method may determine the orientation of an in-vivo imaging device relative to the earth's gravitation field. Some embodiments may enable indication of specific locations where other methods provide non-satisfactory imaging coverage. The system may include an in-vivo imaging system with a container or shell containing an orientation object. The container may be placed in at least one optical dome or optical field of an in-vivo imaging device, such as an autonomous capsule. The location of the orientation object's image on the in-vivo imaging device imager, as well as size of the image, may be determined as functions of the location of the orientation object inside the container, for each image acquired.

Abstract: An imager and a method for real-time, non-destructive monitoring of light incident on imager pixels during their exposure to light. Real-time or present pixel signals, which are indicative of present illumination on the pixels, are compared to a reference signal during the exposure. Adjustments, if necessary, are made to programmable parameters such as gain and/or exposure time to automatically control the imager's exposure to the light. In a preferred exemplary embodiment, only a selected number of pixels are monitored for exposure control as opposed to monitoring the entire pixel array.

Abstract: A system and method for determining the path length through a body lumen, for example to a specified location, is described. A location detection system may identify the location in space of an in-vivo device over time. A path-length detection unit may use data from the location detection system to determine a path traveled by an in-vivo device. A site of interest along that path may be identified. The distance of the site of interest from at least one end point of a body lumen may be determined.

Abstract: A device and method is described for enabling an examining device to pass through an abnormally configured body lumen. The device may pass through a body lumen while maintaining an initial dimension. Upon encounter with an abnormally configured body lumen, the device may be depleted and take on a final dimension after a predetermined time period, regardless of its current orientation with respect to the body lumen, so that the device may pass through and vacate the abnormally configured body lumen shortly after the predetermined time period may have elapsed.

Abstract: A device and system enables obtaining data such as in vivo images from within body lumens or cavities, such as images of the gastrointestinal (GI) tract. A device may include an imaging system and a radio frequency (RF) transmitter for transmitting signals from an imaging device to a receiving system. The signal strength of the transmitter may be varied or changed to account for, for example, the amount of signal attenuation resulting from body tissues.

Abstract: A medical wireless imaging device comprises an image sensor, a transmitter, a receiving device, and a plurality of light sources. The transmitter transmits data through a wireless communication link to a processing device. The receiving device wirelessly receives control data from a control unit. Each light source is configured to be individually controlled according to the control data. A reference image is stored for each light source. Intensities of each light source are calculated based on a reference image and on an input image.

Abstract: An in-vivo imaging device including a ballast that may for example orient such device in a known orientation relative to the gravitational force on such ballast. Such imaging device may, for example, assume a known orientation when it is free to move, and may capture images from such known orientation. The device may include one or more imagers, which may be oriented at different angles or points of view (e.g., forward and transverse). A method of use may include moving a patient so that the device inside the patient images different fields of view.

Abstract: A device, system and method for calculating a size of an object using images acquired by a typically moving imager, for example in the gastrointestinal (GI) tract. A distance traveled by the moving imager during image capture may be determined, and spatial coordinates of image pixels may be calculated using the distance. The size of the object may be determined, for example, from the spatial coordinates. The moving imager may be in a swallowable capsule, or, for example, an endoscope.

Abstract: An in-vivo device, system, and method are described where an in-vivo device may transmit an image stream to an external receiving device. Reducing the size of the image data necessary for transmission may conserve energy consumed by the in-vivo device during transmission. An image data comparator unit incorporated within the in-vivo device may compare a captured image to a previously transmitted image and transmit, for example, only captured images that are substantially dissimilar to a previously captured image.
