Abstract

An array of coils is configured for use in imaging the vasculature of a patient. The array of coils comprises first and second pluralities of coil pairs for deployment longitudinally along anterior and posterior surfaces, respectively, of the patient. In the first plurality, each coil pair has first and second loops positioned laterally about right and left sides, respectively, of the anterior surface for receiving therefrom magnetic resonance signals. In the second plurality, each coil pair has first and second loops positioned laterally about right and left sides, respectively, of the posterior surface for receiving therefrom magnetic resonance signals. Means are provided for laterally isolating the first and second loops relative to each other for each coil pair. Means are provided for longitudinally isolating the coil pairs relative to each other. Means also vertically isolate the coil pairs of the first plurality from those of the second plurality.

Dependent claims

An array of coils configured for use in imaging a vasculature of a patient, said array of coils comprising:

(a) a first plurality of coil pairs for deployment longitudinally along an anterior surface of the patient, each of said coil pairs of said first plurality having first and second loops positioned laterally about right and left sides, respectively, of the anterior surface for receiving from a portion of the patient corresponding thereto magnetic resonance signals emitted thereby;
(b) a second plurality of coil pairs for deployment longitudinally along a posterior surface of the patient, each of said coil pairs of said second plurality having first and second loops positioned laterally about right and left sides, respectively, of the posterior surface for receiving from a portion of the patient corresponding thereto magnetic resonance signals emitted thereby;
(c) means for laterally isolating said first and said second loops relative to each other for each of said coil pairs of said first and said second pluralities of coil pairs;
(d) means for longitudinally isolating said coil pairs relative to each other for each of said first and said second pluralities of coil pairs;
and
(e) means for vertically isolating said coil pairs of said first plurality from said coil pairs of said second plurality.
