ABSTRACT:
An X-ray computer tomography system with a ring anode and substantially without mechanically moving parts for the production of fast image slices from the inside of an object is improved in such a way that a detector ring is comprised of two adjacent parallel partial detector rings of substantially equal size, whereby the detector ring is arranged within and coplanar to the anode ring. The two partial rings of the detector ring are displaced in a direction largely pependicular to the scan slice so that a ring-shaped detector ring gap is formed between them through which the fan beam coming from the focal spot on the anode passes.
