Scanners applied in research use not just one antenna that emits and receives the signal, but several of them, which can cause severe burns to inner tissues and organs. Thus, researchers are forced to power scanners with less voltage, which negatively affects the quality of their studies. Now, ITMO physicists, together with their colleagues from the M-Cube consortium, have created the first ever leaky-wave antennas for MRI scanners. The device can conduct body organ diagnostics without risks for patient health while also raising the quality of images acquired in research scanners.
