GPS for implants in the body
The ReMix system, reminiscent of GPS and tracking implants implanted in the human body, was developed by specialists from the Massachusetts Institute of Technology. The device does not send any signals and is recognized by the system due to its "non-biological" nature. The accuracy of the implant position is about 1 cm.
To test ReMix, the research team first implanted a small marker into animal tissues. To track its movement, the scientists used a wireless device that reflected radio signals from tissues. This is based on wireless technology that was previously used to detect heart rate, respiration and movement. A special algorithm uses this signal to accurately determine the position of the marker.
One of the potential applications of ReMix is proton therapy, that is, the treatment of neoplasms by bombarding tumors with beams of magnetically controlled protons. This approach allows physicians to prescribe higher doses of radiation, but requires a very high degree of precision. ReMix was developed in collaboration with scientists at Massachusetts General Hospital (MGH).
