  • Board-level partitioning in MR-PET imaging system integration
    Patent number: 8969816
    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.

  • High voltage distribution for a radiographic sensor device
    Patent number: 6965110
    Abstract: A high voltage distribution system and method for use with a cathode of a radiographic sensor device of a radiographic imaging apparatus are provided. The distribution system includes an insulated conductor formed on a first detector portion of the radiographic sensor device and communicating a high voltage to the cathode. The distribution system further includes an intermediate conduction portion communicating with the insulated conductor. The intermediate conduction portion includes a contact surface. The distribution system further includes a interconnect extending from a second portion of the radiographic sensor device. The separable interconnect communicates with an electrical voltage source and is positioned to come into contact with the intermediate conduction portion when the first detector portion of the radiographic sensor device is assembled to the second signal processing portion.
