ABSTRACT:
An RF coil construction for MRI apparatus and comprising, preferably, three butterfly coils extending in a longitudinal direction and overlapping with three single loop coils. Each of the three butterfly coils have flexible wings which can be wrapped over the body of a patient. The signals from two of the butterfly coils and two of the single loop coils are simultaneously processed in a phased array manner. The resultant RF coil construction provides in-depth imaging over a large FOV with a high SNR and good homogeniety, and is well suited for imaging the lower extremities of a patient without moving the patient or the coils. Further, the butterfly coils receive signals in the horizontal direction, and the single loop coils receive signals in the vertical direction. The combining of such signals realizes quadrature operation and improves the SNR. Also described is a mesh coil that can be operated to function as the equivalent of one butterfly coil and one single loop coil.
