A Coil System for Multiple-Mouse Imaging at 9.4 T
Gerhard P, Wellen J
A challenging constraint in pre-clinical MR screening applications is the inherently low throughput with MRI. We report on a quadruple coil system for simultaneous imaging of four mice at 9.4T to increase animal throughput. The individual coils are quadrature driven birdcage resonators for transmission and detection. Design, workbench and MR data are demonstrated. Isolation and SNR allow parallel imaging with acceleration factors of up to 4. B1 homogeneity across the coils is sufficient for whole-body mouse imaging applications.
