    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 radiation detector is provided. The radiation detector includes an outer casing, at least one first detector disposed within said outer casing, the at least one first detector configured to primarily detect gamma ray radiation, at least one second detector disposed within the outer casing, the at least one second detector configured to primarily detect neutron radiation, and a computing device disposed within the outer casing and communicatively coupled to the at least one first detector and the at least one second detector. The computing device is configured to receive first data from the at least one first detector, receive second data from the at least one second detector, determine a number of neutrons and gamma rays detected based on the first and second data, and determine a detected energy spectrum based on the first and second data.

    Abstract: An X-ray CT scanner for imaging an object is provided. The scanner includes an X-ray emitter configured to emit X-ray beams, a detector array including a plurality of detector elements, and a precollimator positioned between the X-ray emitter and the object, the precollimator configured to prevent the emitted X-ray beams from being directly incident on a first subset of the plurality of detector elements, and allow the emitted X-ray beams to be directly incident on a second subset of said plurality of detector elements. A processing device communicatively coupled to the detector array is configured to determine a signature of the object based on a first set of data acquired using the first subset of the plurality of detector elements, and tomographically reconstruct an image of the object based on a second set of data acquired using the second subset of said plurality of detector elements.

    Abstract: A controller for detecting objects moving in a first direction in a computed tomography (CT) imaging system is provided. The controller is configured to detect objects by assembling a plurality of segments based on a plurality of CT imaging slices. In response to receiving a stop request, the controller is configured to detect objects by causing the CT imaging system to cease a flow of objects, discarding the one or more of the plurality of CT imaging slices associated with a first segment and a second segment of the plurality of segments, causing the CT imaging system to move the objects in a second direction for an interruption distance in which the second direction is opposite the first direction, causing the CT imaging system to move the objects in the first direction, and reassembling the first segment and the second segment.

    Abstract: A gantry rail for a gantry computed tomography (CT) system includes a secondary side of a rotary transformer and an annular body having an annular rolling surface and an annular slip ring surface. The annular body is aligned orthogonal to a longitudinal axis of the gantry CT system. The annular rolling surface has a normal vector that extends radially outward and orthogonal to the longitudinal axis. The annular slip ring surface defines a plane orthogonal to the longitudinal axis, and includes a slot disposed in the slip ring surface. The slot is configured to engage the secondary side of the rotary transformer.
