The sensitivity of surface coil arrays can be maximized by conforming them closely to the human body, maximizing coil loading and minimizing the contribution of coil noise. There is, however, great diversity in body shape and size. Rigid coils must adopt a compromise, allowing for the largest cases while not giving up too much sensitivity when imaging smaller examples. Flexible arrays can be wrapped tightly around the body, but if the overall array dimensions are fixed there will always be gaps or undesired overlaps depending on body habitus. We present here a geometrical approach based on a trellis-like lattice of interlinked slats which allows a surface coil array to be re-shaped while maintaining coil tuning, coil loading and decoupling of neighboring coils.
