Prostate MRI is commonly performed using endorectal coils which are invasive. This is done since body planar arrays are not sensitive enough for prostate imaging. Increasing sensitivity of an array for deep structures in the body is not trivial. In this study, we extended the traditional stacked figure-8 and single loop quadrature pair to add more single loop coils and enhanced the sensitivity at the depth of the prostate without increasing the field over a larger lateral area. We compared these arrays to classical planar approaches and found a factor 1.35 increase in maximum localized |B₁^-| using numerical simulations.
