3T 8-channel 13C/1H TxRx array for hyperpolarized and steady-state 13C MRSI

Motivation: Tackle the coupling issue among the coil elements in phased array design at low field, so as to use phased array as transceiver at low fields for good transmit efficiency, receive sensitivity profile, and acceleration performance. Goal(s): Design and build a 3T 13C/1H 8-channel array for hyperpolarized 13C MRSI and steady-state 13C MRS after oral uptake of 13C labelled glucoseApproach: Use a novel cable trap decoupling mechanism to decouple the coil elements in the 3T 13C 8-channel arrayResults: Workbench and experiment results show that the coil elements are decoupled very well with each other. Impact: This innovative research on mitigating coil element coupling in low-field phased array designs empowers low-field MRI applications. Enhanced transmit efficiency, receive sensitivity and acceleration performance offer improved diagnostic quality, benefiting scientists, clinicians, and patients.
