Abstract
According to some aspects, a laminate panel is provided. The laminate panel comprises at least one laminate layer including at least one non-conductive layer and at least one conductive layer patterned to form at least a portion of a B0 coil configured to contribute to a B0 field suitable for use in low-field magnetic resonance imaging (MRI).

A laminate panel comprising:
- a plurality of laminate layers, each of the plurality of laminate layers including at least one non-conductive layer and at least one conductive layer patterned to form at least a portion of a magnetics component for use in low-field magnetic resonance imaging (MRI), the plurality of laminate layers comprising:
- at least one first laminate layer having patterned thereon an x-gradient coil configured to, when operated, generate or contribute to a magnetic field to provide spatial encoding of emitted magnetic resonance (MR) signals in an x direction;
- at least one second laminate layer having patterned thereon an y-gradient coil configured to, when operated, generate or contribute to a magnetic field to provide spatial encoding of emitted MR signals in a y direction;
- at least one third laminate layer having patterned thereon an z-gradient coil configured to, when operated, generate or contribute to a magnetic field to provide spatial encoding of emitted magnetic resonance (MR) in a z direction;
- and
- a plurality of electrical connections between the plurality of laminate layers consisting of through-hole vias provided through the plurality of laminate layers of the laminate panel.
