Patent ID: 8259899

Claim:
A multi-modality tomography apparatus comprising (a) a support ring ( 12 ) rotatable around an axial shaft in either of two directions; (b) a first computer-assisted tomograph ( 13 ) supported on a face of the support ring, said first computer-assisted tomograph emitting radiation in a cone-shaped beam and comprising first tomograph detector means for detecting radiation; (c) a second computer-assisted tomograph ( 14 ) having a different operating principle from the first tomograph ( 13 ) comprising second tomograph detector means for detecting radiation, said second tomograph being supported on the face of the support ring; wherein the first tomograph and the second tomograph are disposed on the face of the support ring in a common plane and such that the first and second tomographs have an overlapping effective field of view whereby each of the first and second tomographs can take image samples of the same region of a subject without moving the subject, and wherein the first tomograph detector means and the second tomograph detector means are spaced from one another in a circumferential direction along the support ring.
