ABSTRACT:
There is provided an electron computer tomography method for recording a moving object (27), in which an electron beam is deflected onto an anode arc (14) in order to generate X-ray radiation which passes through an object (27) and is picked up by a detector device (28), wherein the X-ray radiation leaves the anode arc (14) in the form of a fan-shaped beam having a source trajectory (40) in the form of a circle segment around the object (27) and the starting point (41) of the source trajectory (40) can be changed. Also provided is an electron computer tomograph for recording a moving object (27), comprising an electron gun (8), a focusing coil (12), a curvature coil (16), an anode arc (14) for generating an X-ray beam by being struck by an electron beam of the electron gun (8), and a detector device (28) for detecting the X-ray radiation transmitted through a volume (26), said X-ray radiation having a source trajectory (40) in the form of a circle segment at the anode arc (14) and a variable starting point (41) of the source trajectory (40).
