摘要：
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.
