Apparatus for wireless data and power transmission in a computed tomography device

The invention refers to an apparatus for wireless data and power transmission between a fixed frame portion (6) in a computed tomography device and a frame portion (11) capable of surrounding around a rotating shaft (9). The apparatus comprises a first support ring (12) arranged on the rotary frame portion (11) and a second support ring (15) arranged on a fixed frame portion (6), wherein the first and second support rings (12,15) are rotationally symmetrical and are L-shaped in cross section. The invention also provides a computed tomography device with the apparatus. The advantages are that compared with known solving schemes, the apparatus can substantially reduce an external diameter of the supporting rings so as to reduce cost; in addition, the computed tomography device needs less construction space and shortens installation time.
