In March 2018, IEEE Transactions on Medical Imaging published a full research paper from Dr. Xiaotong Zhang’s group, titled “Investigating the Influence of Spatial Constraints on Ultimate Receive Coil Performance for Monkey Brain MRI at 7T”. Ph.D. candidate Yang Gao is the first author.
The RF receive coil array has become increasingly vital in current MR imaging practice due to its extended spatial coverage, maintained high SNR, and improved capability of accelerating data acquisition. In this study, seven hypothetical ultimate coil arrays with different coil-space configurations were mounted over a numerical macaque head model (as shown below), and the influences of coil-space design parameters were systematically investigated through evaluating the spatial constrained ultimate intrinsic SNR (UISNR) and ultimate g-factor (uGF); moreover, simulations were also conducted by using four coil arrays with limited number of loop-only elements, in order to explore to what extent, the ultimate coil performance can be achieved by using practical coil designs, and hence several guidelines in RF coil design for monkey brain imaging at 7T have been tentatively concluded. It is believed that the present analysis will offer important implications in novel receive array design for monkey brain MR imaging at UHF.
