Abstract: A system for image-guided surgery may include a visual imaging system, a medical tool comprising a shaft and a tip, wherein the shaft of the tool includes an optically detectable feature that allows a position of the tip to be determined, and a display configured to display a real-time representation of the medical tool including the position of the tip regardless of whether the tip is obstructed or visible.

Abstract: An augmentation device for an imaging system has a bracket structured to be attachable to an imaging component, and a projector attached to the bracket. The projector is arranged and configured to project an image onto a surface in conjunction with imaging by the imaging system. A system for image-guided surgery has an imaging system, and a projector configured to project an image or pattern onto a region of interest during imaging by the imaging system. A capsule imaging device has an imaging system, and a local sensor system. The local sensor system provides information to reconstruct positions of the capsule endoscope free from external monitoring equipment.
