Abstract:
1. An X-ray generator comprising: a ring-shaped electron beam emission unit that emits electron beams; an electron beam guide unit for condensing the electron beams and causing the condensed electron beams to travel in a predetermined direction, the electron beam guide unit being tubular, with at least a portion shaped substantially as a truncated cone, and having a proximal end and a distal end, the distal end being at a larger diameter end of the truncated cone; and a target unit having a target area facing the proximal end of the electron beam guide unit, for receiving the condensed electron beams and discharging X-rays via collision of the condensed electron beams with the target area; wherein the discharged X-rays are emitted through a central opening of the electron beam guide unit's distal end.
