Abstract

A receiving coil for a magnetic resonance imaging (MRI) apparatus has a cylindrical form including ring-type support members or a cylinder-type support member having open ends, and at least one coil element connected to the support member(s). The receiving coil is configured to receive magnetic resonance signals.

First claim

What is claimed is:

1. A magnetic resonance imaging (MRI) receiving coil comprising:
a first ring-shaped support member disposed around a central axis;
a second ring-shaped support member disposed around the central axis;
a first coil element disposed along a surface of a right circular virtual cylinder formed around the central axis between the first ring-shaped support member and the second ring-shaped support member, and connected to a first point on the first ring-shaped support member and a second point on the second ring-shaped support member; and
a second coil element disposed along the surface of the right circular virtual cylinder, and connected to the first point on the first ring-shaped support member and a third point on the second ring-shaped support member,
wherein the first and second coil elements have a helical shape such that a tangent line at any point on the first and second coil elements forms a constant angle with the central axis.

2. The MRI receiving coil of claim 1 further comprising capacitors forming connections between the first ring-shaped support member and the first and second coil elements, respectively, and between the second ring-shaped support member and the first and second coil elements, respectively.

3. The MRI receiving coil of claim 1 , wherein the first and second coil elements are electrically insulated from each other.

4. The MRI receiving coil of claim 3 , wherein the third point and the second point are symmetrical to each other in a planar area formed by an area surrounded by a second side surface of the second ring-shaped support member and perpendicular to the central axis.
