For human head magnetic resonance imaging at 10.5 tesla (T), we built an 8-channel transceiver dipole antenna array and evaluated the influence of coaxial feed cables. The influence of coaxial feed cables was evaluated in simulation and compared agai

Objective: In dental MRI, intraoral coils provide higher signal-to-noise ratio (SNR) than coils placed outside the mouth. This study aims to design an intraoral dipole antenna and demonstrates the feasibility of combining it with an extraoral coil. M

PURPOSE: Receive array layout, noise mitigation, and B(0) field strength are crucial contributors to SNR and parallel-imaging performance. Here, we investigate SNR and parallel-imaging gains at 10.5 T compared with 7 T using 32-channel receive arrays

Multi-element transmit arrays with low peak 10 g specific absorption rate (SAR) and high SAR efficiency (defined as ( $\text{B}_{{1}}^{+}/\surd _{\text {peak}}$ SAR $_{\text {10g}}{)}$ are essential for ultra-high field (UHF) magnetic resonance imagi

Purpose In this study, we investigate a strategy to reduce the local specific absorption rate (SAR) while keeping B 1 + constant inside the region of interest (ROI) at the ultra-high field (B0 ≥ 7T) MRI. Methods Locally raising the resonance struct

A 16-channel transmit array intended for interchangeable use with up to 128 receiver arrays is being developed for 10.5T/ 447MHz head imaging. In initial work, presented here we evaluated a 16-channel dual row loop array design and compare predicted
