A major challenge in 7T coil array design for body imaging is to achieve optimum distribution in different body sizes with only one coil array. In this work, we propose a flexible 8 channel dipole array with trellis-like substrate which can expand and contract to fit various body sizes and hold electric dipole antenna elements in the optimum distribution around the body for all subjects. The performance of the trellis array was compared with a flexible yet fixed-element-spaced folded dipole body array [1] in terms of flip angle maps and SNR on two different sizes of body phantoms. Both phantom and invivo images show that the trellis array does not have common nulls between the circular polarized (CP) and gradient modes.
