MR ANTENNA WITH COMPENSATION FOR VARIABLE DISTANCE TO SHIELD

摘要

The present invention relates to a total-body coil (102) for a magnetic resonance tomography device (101), the total-body coil includes one or more compensation capacitors (Ck) between a high frequency antenna (108) and a radio frequency (RF) shield (HFS), each of the compensation capacitors has variable capacitance caused by a change in distances (H1, H2, H3) of the HFS to the high frequency antenna.
