Abstract
A MRI coil having an axis and a first end and an opposite second end with respect to said axis includes a first ring element at the first end, a second ring element, a third ring element, a fourth ring element at the second end where the first ring element encompasses a smaller area than each of the second, third, and fourth ring elements. The coil also includes a plurality of axial elements connected between the first, second, third and fourth ring elements. The third and fourth ring elements are axially closer than the first and second ring elements.
Claims20
A MRI coil having an axis and a first end and an opposite second end with respect to said axis, said coil comprising:
- a first ring element at said first end;
- a second ring element adjacent said first ring element;
- a third ring element adjacent said second ring element;
- a fourth ring element at said second end and adjacent said third ring element, said first ring element encompassing a smaller area than each of said second, third, and fourth ring elements;
- and
- a plurality of axial elements connected between said first, second, third and fourth ring elements, wherein said third and fourth ring elements are axially closer than said first and second ring elements.
A MRI coil comprising:
- a first ring element at a first end;
- a second ring element at a second end, said first end opposite said second end with respect to an axis;
- a plurality of intermediate ring elements positioned asymmetrically between said first and second ring elements wherein said first ring element encompassing a smaller area than each of said second ring and said plurality of intermediate ring elements;
- and a plurality of axial elements connected between said first, second and plurality of intermediate ring elements.
A method of magnetic resonance imaging, said method comprising:
- configuring a coil arrangement to include a plurality of intermediate ring elements positioned asymmetrically between a first and second ring elements, said first and second ring elements at opposite ends of said coil arrangement wherein said first ring element encompassing a smaller area than each of said second ring and said plurality of intermediate ring elements.
