Scientists have developed a system called ReMix, which can pinpoint the location of digestible implants inside the body using low-power wireless signals. The marker inside the body does not need to transmit any wireless signal. It simply reflects the signal transmitted by a device outside the body.
As of now the researchers at Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have been able to use algorithms to weed out other frequencies and locate the marker with an accuracy of a few centimeters. With increased accuracy through, this system can be used for proton therapy, which is used in cancer treatment, where it is intended to locate the exact location of the tumor, while also reducing the total cost of the process.
