Abstract
A computed tomography (CT) imaging modality includes a stator and a rotor that rotates relative to the stator. The CT imaging modality includes a radiation source and a detector array for detecting at least some of the radiation. A first data communication component is coupled to the stator or the rotor for transmitting data between the stator and the rotor. The first data communication component includes a first circuit board assembly including a first conductive layer and a first dielectric layer and a second circuit board assembly including a second conductive layer and a second dielectric layer. The second conductive layer of the second circuit board assembly faces the first conductive layer of the first circuit board assembly. An insulating layer is disposed between the first conductive layer of the first circuit board assembly and the second conductive layer of the second circuit board assembly.
