    Abstract: A method of manufacturing an inductor core includes controlling a flow of magnetic material and a flow of binder material to a nozzle such that the flow magnetic material merges with the flow of binder material at a focal point of a preheater, preheating the magnetic material and the binder material by energizing the preheater, mixing the magnetic material and the binder material according to a ratio based on a magnetic permeability distribution of the inductor core, and depositing the magnetic material and the binder material on a surface to form the inductor core having three layers with recessed patterns defined between the layers for receiving a coil.

    Abstract: Arcuate panel includes at least one axially extending panel header with arcuate outer and inner portions. Inner portion includes open portions of axially spaced apart arcuate cooling air spray rails attached to header and in fluid communication with plenum within header. Plurality of axially extending hollow fingers extend axially away from one of the spray rails and impingement spray holes in the spray rails and the fingers. Arcuate overhang may extend axially aftwardly from one of the spray rails and fingers may depend from overhang. An outer casing including axially spaced apart forward and aft casing flanges attached to or integral and monolithic with outer casing may be circumscribed by a hoop of the arcuate panels. The fingers may extend away from one of the spray rails and between nuts screwed on bolts disposed through one of the forward and aft casing flanges.

    Abstract: The embodiments disclosed herein relate generally to magnetic resonance imaging systems and, more specifically, to the manufacturing of a gradient coil assembly for magnetic resonance imaging (MRI) systems. For example, in one embodiment, a method of manufacturing a gradient coil assembly for a magnetic resonance imaging system includes depositing a first layer comprising a base material onto a surface to form a substrate and depositing a second layer onto the first layer. The second layer may enable bonding between a conductor material and the substrate. The method also includes depositing a third layer onto the second layer using a consolidation process. The consolidation process uses the conductor material to form at least a portion of a gradient coil.

    Abstract: A core includes a first layer, a second layer, and a third layer. The first layer has a first surface, a second surface, and a first recessed pattern extending from the second surface of the first layer toward the first surface of the first layer. The second layer has a third surface, a fourth surface, a second recessed pattern extending from the third surface of the second layer toward the fourth surface of the second layer, and a third recessed pattern extending from the fourth surface of the second layer toward the third surface of the second layer. The third layer has a fifth surface, a sixth surface, and a fourth recessed pattern extending from the fifth surface of the third layer toward the sixth surface of the third layer. The second layer is disposed between the first and third layers such that the second surface of the first layer faces the third surface of the second layer and the fourth surface of the second layer faces the fifth surface of the third layer. The first and second recessed patterns correspond to one another and are configured to receive a coil. The first, second, and third layers have non-uniform magnetic permeabilities.
