The intrinsic signal-to-noise ratio (ISNR) performance of a MRI strip detector with lumped tuning capacitors was numerically optimized over a practical range of design parameters. The most important factors determining ISNR performance were found to be strip length, dielectric substrate, and substrate thickness. ISNR analyses showed that optimized strip detectors can yield comparable performance to that of loops optimized for the same depth. A range of strip detectors were fabricated with various design parameters to validate the numerical analyses. The results were in excellent agreement, showing that numerical optimization proves is an effective approach optimizing MRI detector design.
