Abstract
Coils and assemblies for magnetic resonance imaging or spectroscopy, and methods for generating or detecting magnetic fields with coils. The coil includes a first loop and a second loop. The first loop includes one or more capacitors. The second loop includes one or more capacitors. The second loop is connected to the first loop by a conductor. A total capacitance of the first loop is different from a total capacitance of the second loop.
Claims16
A coil for magnetic resonance imaging or spectroscopy, comprising:
- a first loop including one or more capacitors arranged in the first loop;
- and
- a second loop connected to the first loop by a central inner conductor and including one or more capacitors arranged in the second loop, wherein the central inner conductor is part of the first loop and part of the second loop between a first node and a second node,
- wherein a total capacitance of the first loop is a sum of the one or more capacitors arranged in the first loop and a total capacitance of the second loop is a sum of the one or more capacitors arranged in the second loop, and wherein the total capacitance of the first loop is different from the total capacitance of the second loop.
An assembly for magnetic resonance imaging or spectroscopy, comprising a plurality of coils, wherein each of the plurality of coils including:
- a first loop including one or more capacitors arranged in the first loop, and
- a second loop connected to the first loop by a central inner conductor and including one or more capacitors arranged in the second loop, wherein the central inner conductor is part of the first loop and part of the second loop between a first node and a second node,
- wherein a total capacitance of the first loop is a sum of the one or more capacitors arranged in the first loop and a total capacitance of the second loop is a sum of the one or more capacitors arranged in the second loop, and wherein the total capacitance of the first loop is different from the total capacitance of the second loop.
A method for generating or detecting magnetic fields, comprising:
- generating a circularly polarized magnetic field using a coil including:
- a first loop including one or more capacitors arranged in the first loop, and
- a second loop connected to the first loop by a central inner conductor and including one or more capacitors arranged in the second loop, wherein the central inner conductor is part of the first loop and part of the second loop between a first node and a second node,
- wherein a total capacitance of the first loop is a sum of the one or more capacitors arranged in the first loop and a total capacitance of the second loop is a sum of the one or more capacitors arranged in the second loop, and wherein the total capacitance of the first loop is different from the total capacitance of the second loop.
