(a–c). (a) Images of the 28 channel coil (left) and quadrature coil (right). The 28 channel coil consists of anterior and posterior halves, each of which contains 14 receive elements (inset image). (b) SNR maps of the 28 channel coil versus the quadrature volume coil in sagittal, coronal, and axial planes. These maps were generated using the sum-of-squares method from estimates of noise covariance and sensitivities for each coil. (c) SNR profile for the sagittal acquisition showing approximately 300–400% increase in SNR at the periphery of the field of view and approximately 17% increase in SNR at the center of the field of view.
