title: Surface coil with variable geometry: a new tool for MR imaging of the spine.
abstract: A switchable-array surface coil for magnetic resonance (MR) imaging of the spine has been built that enables the user to change the working size of the coil depending on the volume of interest. The prototype has achieved similar image quality to that obtained with conventional coils of equal size. This type of antenna may reduce the number of individual coils necessary for a high-quality MR imaging study.
