We propose a shielded loop coil design for operation as a receive array element at 7T. The proposed coil geometry provides high decoupling between adjacent and non-adjacent loop elements without overlapping or preamplifier decoupling. A four-coil receive array was constructed for high resolution imaging of the knee at 7T. The coil coupling between the elements for in-vivo measurements was lower than -26 dB. Images with an isotropic resolution of 0.7 x 0.7 x 0.7 mm were acquired in five minutes.
