MAGNETIC RESONANCE IMAGING RF ANTENNA

摘要

The invention provides for an RF antenna system (100, 1014, 1014′) for transmitting RF excitation signals into and/or for receiving MR signals from an MR imaging system's (1000, 1100, 1200) imaging volume (1015). The magnetic resonance imaging antenna comprises: a coil former (100, 1014, 1014′) adjacent to the imaging volume (1015); and a resonator (400, 500, 600) attached to the coil former and tuned to at least one resonant frequency formed from electrical connections (304), between multiple capacitors (302). The multiple capacitors are distributed in a periodic pattern (300, 700, 800, 900) about and along the coil former.
