Patent ID: 7580500

Claim:
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, each said saw-toothed element including an irradiation target and a respective compensating body.
