ABSTRACT:
A computer tomograph (1) that comprises at least a stationary electron source for generating an electron beam (13), a ring-shaped, stationary X-ray source with a largely ring-shaped target (14) enclosing a measuring field (7), media for coaxially guiding (22) the electron beam (13) in the X-ray source (5) along a circular path to the ring-shaped target (14), as well as media for deflecting (21) the electron beam (13) towards the target (14), in order to generate an X-ray cluster (8) that rotates concentrically around itself for irradiating the measuring field (7) from various directions. Furthermore, the computer tomograph (1) comprises a stationary detector (6) executed as a ring shape and consisting of numerous detector elements from which a computer calculates the measured values to create an image of the examined object in the measuring field (7). The ring-shaped target (14) has numerous discrete focal areas (20) that can be scanned discontinuously by a focal point of the electron beam (13′).
