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.
