Needle-size device created to track tumors, radiation dose

Engineers at Purdue University are creating a wireless receiver that can be injected into tumors and tell doctors their location and other vital information such as how much radiation a tumor receives. This device uses RFID technology which is completely harmless to the body, unlike x-rays, which is often used as an imaging technique during radiation treatments. With this device we now have a safe cost effective way to track tumors in the body and track the progression of treatment.
