Abstract

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.
