Claim 1
Independent Claim
258 words
A receiver coil structure for NMR imaging of a human head attached by a neck, having ear positions, and having a defined axis generally along a line extending from the top of the head through the neck, said coil structure comprising: a coil lying primarily in a coil plane; said coil being generally oval in configuration with sides and defined upper and lower ends spaced by an oval height; said coil being sized for positioning around the head oriented such that the coil upper end is adjacent the top of the head, the coil sides are generally adjacent the positions, and the defined head axis lies in the defined coil plane; said coil being formed of a conductor which is tubular and of a material which has good electrical conductivity; and said coil including an angled segment defined as having a midpoint at the coil lower end and extending from the midpoint along the coil sides towards the coil upper end for a distance corresponding to approximately one-third of the oval height to segment endpoints, said angled segment diverging beginning at the segment endpoints out of the coil plane at an angle such that the coil lower end clears the neck when positioned around the head, and further comprising a component unit located at the upper end of said coil, said coil having terminal ends at the upper end, said component unit mounted to bridge said terminal ends, and said component unit including a capacitor electrically connected to the coil terminal ends to form a parallel resonant circuit.
