Abstract: A system for electron beam X-ray computer tomography, which requires no considerable axial extension of the electron emitter and substantially eliminates electron-optical beam guidance elements is provided by disposing an X-ray detector arc and the target around the examination cross-section within an irradiation plane, and radially introducing an electron beam generated in the electron beam generator into the magnetic flux region of one or more longitudinal coils from within or outside the coils and forcing the same onto a circular path by way of the magnetic field. By periodically changing the field strength, the radius of the circular path is increased, as a result of which the electron beam impinges on the target in a tangentially migrating focal spot. Radiography projections of the object located in the center of the system are recorded by the X-ray detector surrounding the target, the target and x-ray detector planes being with or without axial offset.
