Abstract: A printed circuit board (PCB) assembly of a data processing unit for an integrated magnetic resonance (MR) and positron emission tomography (PET) system, the PCB assembly includes a plurality of PCB layers disposed in a stacked arrangement, first and second PET signal processing circuits carried by a first layer of the plurality of PCB layers, first and second ground plane structures carried by a second layer of the plurality of PCB layers and configured relative to the first and second PET signal processing circuits, respectively, and a ground partition that separates the first PET signal processing circuit from the second PET signal processing circuit on the first layer. The ground partition extends through the first layer to provide electromagnetic interference (EMI) shielding between the first and second PET signal processing circuits.

Abstract: An integrated magnetic resonance (MR) and positron emission tomography (PET) system includes an MR scanner including a magnet that defines an opening in which a subject is positioned, a set of PET detectors disposed about the opening, a plurality of data processing units each electrically connected with a respective one or more of the PET detectors of the set of PET detectors, and a plurality of power supply modules, each power supply module being operable to generate a DC power supply for different groups of one or more of the data processing units. Each power supply module is discrete from the other power supply modules.

Abstract: First and second scintillation camera detectors are provided and are mounted, respectively, to first and second yoke assemblies. The first yoke assembly is mounted to a ring gear which is rotatable within a vertical plane about a horizontal axis. The second yoke assembly is mounted to an annulus which is located within the ring gear and which is rotatable within the plane and about the axis. A rotating device is provided for rotating the ring gear in the plane and about the axis and a locking device is also provided for locking the first and second yoke assemblies together, whereby the first and second yoke assemblies rotate together when they are locked together and the first yoke assembly is being rotated by the rotating device. Advantageously, each detector is pivotally secured to its corresponding yoke assembly and each of the detectors is radially movable towards and away from the axis of the gantry. Further advantageously, the entire gantry is laterally moveable.
