Three-row MRI receive array with remote circuitry to preserve radiation transparency Open
Objective. Up to this point, 1.5 T linac-compatible coil array layouts have been restricted to one or two rows of coils because of the desire to place radiation-opaque circuitry adjacent to the coils and outside the window through which th…

Improved whole‐brain SNR with an integrated high‐permittivity material in a head array at 7T Open
Purpose To demonstrate that strategic use of materials with high electric permittivity along with integrated head‐sized coil arrays can improve SNR in the entire brain. Methods Numerical simulations were used to design a high‐permittivity …

Improved brain imaging with a head array with integrated high-permittivity material Open
High electric permittivity materials (HPM) have been used to improve transmit efficiency and receive sensitivity in targeted regions. In this work we demonstrate improvements in the entire b rain by designing and implementing an integrated…
