发明名称 HIGH-FREQUENCY COIL FOR NUCLEAR MAGNETIC RESONANCE
摘要 <p>PURPOSE:To make possible the generation of a high-frequency electromagnetic wave having excellent special uniformity by coupling capacitively the 1st and 2nd conductor pairs which are disposed parallel and symmetrically to a pair of annular conductors at both ends thereof. CONSTITUTION:The annular conductors 1, 2 are disposed symmetrically with the plane perpendicular to the same axial line CL. The conductors 3-6 are capacitively coupled at both ends to the annular conductors 12 via dielectric layers 7, 8 by the straight conductors parallel with the axial line CL. The current from a terminal 9 is bisected to the conductors 4, 6 by an input high-frequency signal and flows to the annular conductor 2 side through the conductors 4, 6 as shown by an arrow. The current is passed through the annular conductor 2 toward the conductors 5, 3 by the capacitive coupling and is passed further through the conductors 5, 3 as shown by the arrow toward the annular conductor 1 side by the capacitive coupling. These currents are passed through the annular conductor 1 by the capacitive coupling so as to arrive at a terminal 10. The distribution of the magnetic lines of force generated in this stage is such that the greater part of the magnetic lines of force are perpendicular to the axial line CL and are parallel with the arranging direction of the conductors 4, 6 and are approximately uniformly distributed in the space enclosed by the conductors 3-6.</p>
