Navigating Through The Bloodstream

Can you guess if this is a journal article or press report based on the title: Automatic navigation of an untethered device in the artery of a living animal using a conventional clinical magnetic resonance imaging system? Yes it is a journal article:

The feasibility for in vivo navigation of untethered devices or robots is demonstrated with the control and tracking of a 1.5 mm diameter ferromagnetic bead in the carotid artery of a living swine using a clinical magnetic resonance imaging (MRI) platform. Navigation is achieved by inducing displacement forces from the three orthogonal slice selection and signal encoding gradient coils of a standard MRI system. The proposed method performs automatic tracking, propulsion, and computer control sequences at a sufficient rate to allow navigation along preplanned paths in the blood circulatory system.

Pretty cool. See more interesting papers and information from the NanoRobotics Laboratory including online videos and more info online.
