چکیده
FLASH images obtained with the antenna, Fig.2B shows images received with the two channels separately. D is a coronal FLASH image obtained with an elliptical 16-channel T/R microstrip array. Figure 1: Antenna (A) and the tuning/matching circuit (B) of one channel. Fig.1C shows the driving voltage (black) necessary to scale the B1+ field to a reference value when the antenna is placed at various distances to the head as well as the resulting SAR (red).

متن کاملHuman Brain Imaging at 9.4 Tesla Using a Combination of Traveling Wave Excitation with a 15-channel Receive-only Array
Introduction The combination of a circularly polarized (CP) volume coil for spin excitation with a multi-channel receive-only array is a successful setup for routine human brain imaging at 7 Tesla. For reception, the use of multiple surface coils is important for a high SNR and for the utilization of parallel imaging techniques. For transmission, the main strength of the CP coil is the reasonab...
متن کاملTraveling Wave Imaging of the Human Head at 7 Tesla: Assessment of SNR, Homogeneity and B1+ Efficiency
Introduction: The traveling wave concept for 7T MR imaging was first demonstrated by Brunner et al [1]. In the most common RF transmit coil designs, a quadrature RF field is created within a cylindrical volume in the near-field regime. In contrast, the traveling wave approach creates a traveling wave mode down the entire bore of the scanner. This has the potential to provide more uniform excita...
متن کاملDual Band Slotted Patch Antenna for On/Off-body Communication
Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...
