Abstract
An emitter for a cathode of an X-ray tube is provided that includes a shaped emitting surface. The emitting surface is shaped in a suitable process in order to enable the emitting surface to focus electron beams emitted from the emitting surface on a focal spot on a target of less than 1.0 mm without the need for any additional focusing elements in the X-ray tube.
