Claim:
1. A tomographic apparatus for examining a brain or a limb of a human and/or a primate animal, the apparatus comprising: an examination space adapted for receiving a subject of a tomographic examination, and a PET ring arranged around the examination space in a substantially coaxial manner, wherein the PET ring is displaceable between a PET operational state and a PET non-operational state; and a second imaging arrangement arranged around the examination space in a substantially coaxial manner, wherein the second imaging arrangement is adapted for being brought from a second imaging non-operational state to a second imaging operational state in the PET non-operational state of the PET ring, the second imaging arrangement is a CT arrangement having a radiation source and a detector corresponding to the radiation source, in the PET operational state the PET ring is moved into between the radiation source, and the detector of the CT arrangement, while in the PET non-operational state, the PET ring is moved out from between the radiation source and the detector of the CT arrangement, and in the second imaging operational state, the detector of the CT arrangement is displaced towards the radiation source from the position the detector has in the second imaging non-operational state such that in the second imaging non-operational state the PET ring is allowed to be inserted between the radiation source and the detector of the CT arrangement.
