Abstract
In radiographic apparatus in which a source of radiation and detectors receiving the radiation are orbited about a position for locating a patient, the examination can be carried out using a rotation through 360.degree. or more. This arrangement uses slip rings for carrying data, including the output of the detectors and provides a slip ring arrangement suitable for high speed use. The slip rings can have capacitative coupling to avoid data loss if the brushes are allowed to bounce and for use therewith the data should be encoded in a D.C.-component-removing digital code.
