ABSTRACT:
In MRI (Magnetic Resonance Imaging), the signal-to-noise ratio with nuclear magnetic resonance signals received by a surface coil from an excited body is considerably larger than with corresponding signals received by a body coil in the relevant region. The sensitivity pattern of a surface coil is very non-uniform, however. By correction of a reconstructed image from MR signals received by a surface coil by a corresponding image from MR signals received by a body coil, in which event the surface coil has an arbitrary shape and occupies an arbitrary position with respect to the body, the non-uniformity in the surface coil image is brought back to the uniformity of the body coil image.
