System and method for automatic navigation of a capsule based on image stream captured in-vivo
First Claim
1. A method for automatic generation of a model of an organ, the organ imaged by an in vivo capsule comprising an imager, the method comprising:
- capturing, via the in vivo capsule, light-based images in-vivo;
generating, by a computer data processor, an initial organ model being a three-dimensional hollow geometric shell representing an inner surface of an organ within a body, the initial organ model based on a predetermined estimated structure of the imaged organ;
receiving, by the computer data processor, a user indication of an image captured while the in vivo capsule images a first point of interest to a user identified in the imaged organ;
determining a position and orientation of the in vivo capsule upon capturing the indicated image of the first point of interest;
based on the position and orientation of the in vivo capsule, updating, by the computer data processor, the initial model to a customized model, such that a location in the customized model corresponding to the position of the point of interest in vivo reflects the organ size and organ location within the body; and
based on the customized model and images captured by the in vivo capsule, constructing, by the computer data processor, a three-dimensional visualization of the organ including the images for display to the user.

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.
