Abstract: A line-frequency rotary transformer is provided, including a primary core and a secondary core. The primary core is magnetically couplable to the secondary core. The primary core includes a first plurality of E-core steel laminates arranged in a first ring couplable to a stator. The primary core includes a primary winding disposed within the first ring and configured to transmit line-frequency AC power. The secondary core includes a second plurality of E-core steel laminates arranged in a second ring couplable to a gantry. The gantry is rotatably couplable to the stator. The secondary core includes a secondary winding disposed within the second ring and is configured to receive a line-frequency AC power induced in the secondary winding through the primary core and the secondary core by the primary winding.

Abstract: A gantry system for use with a computed tomography (CT) imaging system is provided. The gantry system includes a gantry assembly configured to rotate about a rotational axis to collect imaging data from an object. The gantry assembly includes a support rail. A radially inner surface of the support rail includes a canted first portion and an oppositely canted second portion. The gantry system also includes a plurality of roller assemblies rotatably supporting the gantry assembly. Each of the plurality of roller assemblies comprises a first roller sleeve configured to engage the first portion and a second roller sleeve configured to engage the second portion.
