Abstract
A magnetic resonance (MR) receive coil (18) includes a conducting loop (20) that is resonant at a Larmor frequency of a design-basis B0 magnetic field of at least 3 Tesla; and a conducting trace (22) configured to detune the conducting loop from the Larmor frequency in response to a DC current flowing through the conducting trace. The conducting trace further includes a receive |B1|-field uniformity-enhancing inductor (L3) positioned at an intermediate point along the conducting trace.
Claims20
A magnetic resonance (MR) receive coil, comprising:
- a conducting loop that is resonant at a Larmor frequency of a design-basis B0 magnetic field of at least 3 Tesla;
- and
- a conducting trace configured to detune the conducting loop from the Larmor frequency in response to a DC current flowing through the conducting trace, the conducting trace further including a receive |B1|-field uniformity-enhancing inductor positioned at an intermediate point along the conducting trace.
A method of optimizing receive |B1|-field uniformity of a magnetic resonance (MR) receive coil, the method comprising:
- placing the MR receive coil in a design-basis B0 magnetic field of at least 3 Tesla with the MR receive coil coupled with a dielectric body, the MR receive coil including:
- a conducting loop that is resonant at a Larmor frequency of design-basis B0 magnetic field, and
- a conducting trace configured to detune the conducting loop from the Larmor frequency in response to a DC current flowing through the conducting trace, the conducting trace further including a receive |B1|-field uniformity-enhancing inductor positioned on a portion of the conductive trace oriented parallel with the design-basis B0 magnetic field;
- and
- adjusting one or more components of the MR receive coil including at least the receive |B1|-field uniformity-enhancing inductor to optimize receive |B1|-field uniformity of the MR receive coil placed in the design-basis B0 magnetic field and coupled with the dielectric body.
