| 6. A computer tomography system, comprising:
at least one stationary electron source configured for generation of an electron beam;
a ring-shaped stationary X-ray source enclosing a measuring field, said X-ray source comprising a ring-shaped target and media
arranged for coaxially guiding the electron beam along a circular path towards said target, and media arranged to deflect
the electron beam towards the target for generation of an X-ray bundle that irradiates said measuring field from different
directions;
a stationary detector arranged in a ring shape and comprising a plurality of detector elements used for computer generation
of an image being examined in said measuring field;
said ring-shaped target comprises a plurality of discrete focal areas arranged such that said plurality of focal areas are
discontinuously scanned through respective focal points of the electron beam; and
wherein said ring-shaped target comprises a stepped ring structure with an odd number of saw-toothed elements configured thereon.
