A method of data acquisition at a magnetic resonance imaging system is provided. The pipeline support electrically insulates the pipeline from the piling without using an insulating block disposed between the pipeline support and the piling. The throat height is determined by the end close to the bottom pole tip of the insulating layer. A first finger is positioned laterally to a first edge of the publication and a second finger is positioned laterally to a second edge of the publication. When the paired electrode device is operably connected to the paired electrode interface port and actuated, the switching device alternates energy such as bipolar RF from the first pair of opposed electrodes to the second pair of opposed electrodes.
