To provide localized sensitivity and to adapt to spatiotemporal resolution enhancement by parallel MRI, we develop a 16-channel linear planar array for brain imaging at 3T. The size of the array is about 10 cm x 10 cm with 16 slim rectangular distributed over two sides of a circuit board. Isolation between channels brought by appropriate overlapping and pre-amplifier decoupling is demonstrated with minimal noise correlation. Preliminary experiment results demonstrate up to 4x acceleration of human temporal lobe structure imaging with 1 mm spatial resolution.
