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. |
