Gurus at Purdue University have conjured up a prototype device which, when injected into a tumor, can actually track the "precise dose of radiation received and locate the exact position [of the tumor] during treatment." Currently, the needle-sized device is held within a hermetically sealed glass capillary, contains a miniature radiation dosimeter, operates without batteries and instead relies on "electrical coils placed next to the patient" for activation. As small as the RFID-enabled unit is, engineers are still hoping to create a version that is around the size of a grain of rice, and hopes are to have it in clinical trials in 2010.
