Is there any research showing that the technology negatively impacts the functionality of imaging devices?
Researchers at St. Gallen Canton Hospital, in Switzerland, conducted a study about five years ago, which found that high-frequency (HF) 13.56 MHz RFID tags do not significantly interfere with the functionality of imaging devices, nor do those devices affect the tags’ functionality. The study, undertaken by physicians and researchers at the hospital, as well as at the University of ETH Zurich, determined that MRI radiation could raise the temperature of tissue around an RFID tag by, at most, 4 degrees Celsius (7 degrees Fahrenheit), but that it had no effect on a patient’s health (see Swiss Study Finds RFID Tags Safe for MRI, CT Scans). During another study, titled “Safety and Reliability of Radio Frequency Identification Devices in Magnetic Resonance Imaging and Computed Tomography,” RFID transponders in wristbands worn by patients did not significantly affect MRI machines or suffer data loss.
