Artist's conception of wireless devices moving through the gastrointestinal tract.

The new platform includes an ingestible microdevice for the anatomical mapping of the gastrointestinal tract, which interfaces with a wireless Bluetooth receiver (such as a smartphone) to map field data to the corresponding spatial location.

Researchers at Boston’s Brigham and Women's Hospital, the Massachusetts Institute of Technology, and the California Institute of Technology have created a system that three-dimensionally (3D) tracks wireless ingestible devices throughout the gastrointestinal (GI) tract.

The ingestible device that maps the GI tract (iMAG) engages with a wireless Bluetooth receiver to correlate field data to spatial location for real-time tracking as it travels through the body.

The system produces a 3D magnetic field via electromagnetic coils positioned at the patient's back.

The researchers found the iMAG could measure activity in a pig's gut accurately when tracked with magnetic fields and X-rays.

Brigham's Giovanni Traverso said, "Such a portable and non-invasive procedure holds the potential for significant clinical benefit without causing patients discomfort."
