## Abstract An MRI detector is formed from a conducting strip separated by a dielectric substrate from a ground plane, and tuned to a quarter‐wavelength. By distributing discrete tuning elements along the strip, the geometric design may be adjusted to optimize the signal‐to‐noise ratio (SNR) for a

✦ Synopsis
Communicated by G. F. Roach
The authors consider the optimization of the signal-to-noise ratio of an arbitrary cylindrical antenna array. Existence of an optimal solution and convergence of finite-dimensional approximations is shown. The necessary optimality conditions are used to compute optimal solutions for some numerical examples.
L'(l-1 and C(S) are equipped with their canonical norms.

## Abstract Measuring signal‐to‐noise ratio (SNR) for parallel MRI reconstructions is difficult due to spatially dependent noise amplification. Existing approaches for measuring parallel MRI SNR are limited because they are not applicable to all reconstructions, require significant computation time
