Cross-coupled double loop receiver coil for NMR imaging of cardiac and thoraco-abdominal regions of the human body |
摘要 |
An RF receiver coil structure for NMR imaging of cardiac and thoraco-abdominal regions of a human body. The coil structure includes a coil of generally solenoidal geometry having two turns separated by an inter-element gap. The inter-element gap is sufficiently large to accommodate an average human torso at the chest level (e.g. 25 cm). The turns are cross coupled by a pair of crossed diagonal elements. The coil is formed of a tubular conductor, having a tubular diameter (outside diameter) of approximately 1/2 inch. The coil has terminal ends in one of its diagonal elements, and the coil structure further includes a component unit located where the diagonal elements cross. The component unit includes a capacitor electrically connected to the coil to form a parallel resonant circuit. The same geometry may be employed in a multi-turn structure, where preferably one-half of the total number of turns are positioned above the patient, and the other half below the patient.
