This study tested whether GSM-like RF exposure affects resting human EEG, focusing on alpha band power and non-linear EEG features. Using a fully counterbalanced cross-over design with 12 participants and a dipole antenna intended to better resemble handset exposure, the authors found no changes after 15 minutes of…

Jan 1, 2007
This engineering study describes development of a patch antenna array coil (PAAC) intended to address short RF wavelength challenges in ultra-high-field (≥7T) MRI. A prototype PAAC for 7T proton imaging was used to image a monkey brain. The authors report that the imaging demonstrated the coil's utility for…
