Abstract:
A Magnetic Resonance Imaging (MRI) phased array head coil (10) comprises an array of coils (1, 2, 3, 4) a decoupling circuit (7) and a decoupling base (14). Counter wound inductors from adjoining coils (1, 2, 3, 4) in the decoupling circuit (7) are interlaced to achieve mutual decoupling between adjoining coils. Each separate coil (1, 2, 3, 4) includes a pair of spaced parallel main conductors (12) located on opposite sides of a cylindrical space (5) enclosed by the coils (1, 2, 3, 4). The decoupling base (14) comprises two meandering conductor bases (8, 9) which are interlaced. Orthogonal main conductors (12) of the coil (1, 2, 3, 4) share a common conductor base (8, 9). The multiple crossings of the paths of the conductor bases (8, 9) reduces mutual coupling effects.
