    摘要: Methods of tagging cancerous tissue for diagnostic applications, mainly for cancer screening purposes, include oral or luminal administrating of a tag molecule into a patient's gastrointestinal lumen either orally or through an enema, and tagging cancerous tissue present within the lumen with the tag molecule. The tag molecule may be a near infrared dye, e.g., IR783 or a derivative thereof, which showed to be of high concentration within cancerous tissue compared to normal tissue. The near infrared IR783 dye is administered, either orally or through an enema, as part of a pharmaceutical composition or formulation either as is or conjugated to a specific polymer. The formulation may comprise an enteric coating in order to keep the formulation intact prior to it reaching the target organ, which is to be tagged by the formulation.

    摘要: An in-vivo device captures images of the GI system and transfers frames to an external system for analysis. As frames are transferred from the in-vivo device to the external system frames may be classified as belonging to a particular GI section. Based on statistical analysis of the classes, a temporary determination may be made, that the in-vivo device has transitioned to a “target section”, and, as a result of the temporary determination, the operation mode of the in-vivo device may temporarily change from a first mode to a second mode. If the temporary determination is followed by a determination which is based on analysis of additional classes, the determination that the in-vivo device is in the target section may be made final and the in-vivo device may remain in the second mode. Otherwise, the first operation mode may be resumed and the whole transition determination process may start anew.

    摘要: A system and method for classification of images of an image stream may include receiving an image stream of unclassified images, for example produced by an in-vivo imaging device, and based on indirect user input, adapting an initial classification algorithm to classify images to groups based on at least a subset of the received image stream of unclassified images.

    摘要: Device, system and method for in-vivo detection of H. pylori. For example, an in-vivo device includes a housing, a reference electrode disposed on the housing, and a working electrode disposed on the housing in close proximity to the reference electrode. The working electrode is coated by litography or screen printing with salt such that substantially no current passes between the working electrode and the reference electrode. The in-vivo device further includes a measuring device for measuring current, impedance, and/or resistance between the working and the reference electrodes, and a transmitter for transmitting the measurements. Presence of ammonia, which is a byproduct of H. pylori, causes increase in current and thus decrease in impedance or resistance between the reference electrode and the working electrode; thereby measurements of current, impedance, and/or resistance indicate on presence or absence of H. pylori.

    摘要: A method and system for automatically detecting villi texture in in-vivo images. In-vivo images may be received from an in vivo imaging capsule, and at least one image may be selected for analysis. Textural details may be extracted, for example using morphological top hat transforms. The image may be divided into segments or patches. The patches may be pruned using a set of threshold conditions, which are calculated based on grayscale or color statistics of the patches. The patches may be classified as containing villi texture or not based for example on rotation-invariant textural features computed in the Fourier domain. A sum, score or rating for the image may be calculated based on the classification of each patch. The final score of the image may be averaged over a number of, for example, consecutive images, and the score may be used for detecting entry into the small bowel and segmenting the image stream to anatomical regions.

    摘要: An assembly for aligning an optical system over an image sensor is described. The assembly may include a lens structure positioned over an image sensor and a lens holder positioned over the lens structure and secured onto a substrate. The lens structure may incorporate an optical section and a structural section extending from the optical section and may rest directly on an image sensor with one or more stoppers that may serve to elevate the optical system with respect to the image sensor at a distance corresponding to a near optimal focal length distance. A lip also included in the structural section of the lens structure may abut two or more opposing sides to secure the lens structure over the image sensor in a centered position with respect to the image sensor.

    摘要: An in-vivo examining device, system and method for identifying the presence of strictures in the small bowel are provided. The in-vivo examining device includes a monitoring mechanism that becomes deactivated when exposed to in-vivo substances native to the small bowel or the colon, and a degradable device body that includes at least a first body portion which degrades at a slow rate when exposed to in-vivo substances native to the small bowel and at a fast rate when exposed to in-vivo substances native to the colon. The degradation of the degradable device body exposes the monitoring mechanism to substances native to the small bowel or the colon and thus indicates whether the examining device has safely passed through the small bowel or whether it is retained in the small bowel due to strictures in the small bowel.
