8-Channel Eigenmode Tx-Array at 3T for Tx-SENSE
نویسندگان
چکیده
Introduction Tx-SENSE is used to reduce the pulse length of 2D and 3D spatially selective RF pulses. The design of array coils for Tx-SENSE applications is complimentary to the design of an array for Rx parallel MRI. Therefore, Tx-array elements that have B1 field distributions that are completely orthogonal may allow the complimentary effect of data compression [1] but on the transmit side for Tx-SENSE applications, minimizing the number of transmit channels required to achieve a certain Tx-SENSE reduction factor. Here we report on an eigenmode [1,2] Tx-array solution that generates 8-channel orthogonal B1 fields used in conjunction with an 8-channel transmitter MRI system for Tx-SENSE MRI.

متن کاملSlot-line antenna array for high field parallel transmit MRI
Objective Parallel transmission is receiving more and more attention in MRI, and multi-element transmit MRI systems become commercially available. A number of different Tx/Rx antenna types have been presented for usage in parallel transmit configurations: degenerate birdcage coils, decoupled TEM or stripline coils [1,2,3]. All of these ‘traditional’ coil-types have their pro’s and con’s. We pro...
متن کاملComparison of Whole Body Transmit Coil Configurations for RF Shimming at 3T
Introduction Whole body MRI at 3T may be impeded by B1 transmit field inhomogeneities caused by the dielectric shortening of the RF wavelength [1]. RF shimming techniques based on parallel transmission [2,3] can strongly improve the image quality in clinical whole body applications [4]. In this context, it is an important question, how the RF shimming performance depends on the chosen coil topo...
متن کاملA comparison of measured 8×8 MIMO systems with a popular stochastic channel model at 5.2GHz
We compared the average capacities of measured 8×8 MIMO systems with the capacities calculated from a popular stochastic MIMO model. This model separates the influence of fading from the correlation at transmit (TX) and receive (RX) arrays. By using directional RX antennas and a virtual 20×10 TX array with omni antennas we measured the MIMO channel at different RX positions in an indoor office ...
متن کامل1H/23Na dual-tuned RF Unicoil for human body MR imaging at 3T
[Introduction] When a radio frequency (RF) coil is designed and built for MR imaging, its performance is judged on the basis of achieving uniform imaging B1field and high signal-to-noise ratio (SNR). However, there is an intrinsic trade-off between B1-field uniformity and high SNR in the configuration of RF coil; a large RF coil tends to generate a more uniform B1-field but lower SNR, because i...
