Loops are usually overlapped by approximately 10% in area to minimize the mutual inductive coupling. Due to geometrical constraints, the size of each loop has to be reduced to increase the numbers of coils in an array. In this work, we propose a simple loop array design that achieves over-overlap as well as low reactive/resistive coupling. A 40% overlap was chosen in this study. Numerical results show that the proposed over-overlapped loop arrays could increase the performance of parallel imaging and SNR.
