An electron beam x-ray computer tomography scanner is improved so that a compact, tiltable configuration without mechanical motion is achieved. By introducing the electron beam in a direction which is largely parallel rather than perpendicular to the scan plane, the long large diameter evacuated electron beam pipe of prior art is eliminated. As a result, the scan system according to the invention enjoys compact dimensions compared to those of prior art, and free access to the scan region from both the front and back of the scanner is possible.

Electron beam x-ray computer tomography scanner

An X-ray computer tomography system with a stationary ring anode and a plurality of stationary electron sources for the construction of fast scan images from the inside of an object is improved in such a way that there is free access from both sides of the scan region, that the gantry unit can be tilted, and that the image quality which can be achieved is comparable to that of conventional tomography systems with mechanical motion of the anode. A plurality of electron sources are configured in proximity to the ring anode on a stationary ring, with each source being capable of sweeping its respective electron beam over a portion of the anode ring.

X-ray computer tomography system

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.
