Abstract

The invention relates to an X-rayimaging system (100) like a CT-scanner. In a preferred embodiment of the system, a cylindrical X-raydetector(130) is sandwiched between two cylindrical X-raysources (110, 120) or vice versa. The X-raysources preferably comprise cathodes with carbon nanotubes and a multitude of focal spots(111) that can selectively be controlled. The cylinder-diameters of the X-raysource and the X-raydetector may be the same or, preferably, be different. Moreover, the X-raysource and the X-ray detector preferably extend circumferentially over less than the full angle of 360°.
