Patent ID: 7493001

Claim:
An apparatus comprising: a computer tomograph having a detector module for at least one of x-radiation and gamma radiation, the detector module having, at least one optical waveguide section, arranged to form at least one detector row, the at least one optical waveguide section including at least one converter materials for converting incident at least one of x-radiation and gamma radiation into optical radiation and designed in such a way that optical radiation of different wavelength is generated in respectively neighboring regions along the at least one waveguide section upon incidence of at least one of x-radiation and gamma radiation, wherein the detector module is arranged on a rotating part of the computer tomograph, and an optical slip ring, connected to an output of the detector module, for transmitting the generated optical radiation to a stationary part of the computer tomograph on which is arranged a light measuring device that resolves at least one of frequency and time.
