A General Design Approach and Practical Realization of Decoupling Matrices for Parallel Transmission Coils
Purpose—In a coupled parallel transmit (pTx) array, the power delivered to a channel is partially distributed to other channels because of coupling. This power is dissipated in circulators resulting in a significant reduction in power efficiency. In this paper, a technique for designing robust decoupling matrices interfaced between the RF amplifiers and the coils is proposed. The decoupling mat...

متن کاملCurrent CONtrolled Transmit And Receive Coil Elements (C2ONTAR) for Parallel Acquisition and Parallel Excitation Techniques at High-Field MRI
A novel intrinsically decoupled transmit and receive radio-frequency coil element is presented for applications in parallel imaging and parallel excitation techniques in high-field magnetic resonance imaging. Decoupling is achieved by a twofold strategy: during transmission elements are driven by current sources, while during signal reception resonant elements are switched to a high input imped...
متن کامل7T Human Spine Arrays with Adjustable Inductive Decoupling
Introduction Ultrahigh field parallel imaging at 7T has been proven to be a promising imaging modality for humans because it can provide high spatial and temporal resolution simultaneously [1-4]. However, one of technical challenges in implementing ultrahigh field parallel imaging is to design the required transceiver arrays, especially the large size arrays, for signal excitation and reception...
