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…

This engineering-style study measured voltage induced on the human body via capacitive coupling to the environment using a high-impedance measurement head. It then applied earth grounding through a conductive patch and a conductive bed pad. Both grounding methods reportedly reduced coupled 60 Hz mains voltage by at…

This exposure assessment measured 20 kHz magnetic field leakage from induction cooking heaters across four models and compared results with ICNIRP general public limits. The maximum reported magnetic flux density was 16 µT at a specified measurement point using two S-type pans. Field leakage depended on pan size and…
