Abstract
An X-ray generator and an X-ray photographing apparatus including the X-ray generator generate characteristic X-rays. The X-ray generator includes an electron beam emission unit that emits electron beams; an electron beam guide unit, in which the electron beam emission unit is disposed, for condensing the electron beams and causing the electron beams to travel in a predetermined direction; and a target unit disposed to face the electron beam guide unit, and discharging X-rays when the electron beams collide with the target unit.
Claims25
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.
An X-ray photographing apparatus comprising:
- an X-ray generator;
- and
- an X-ray detector for detecting X-rays discharged from the X-ray generator through an object;
- wherein the X-ray generator comprises:
- 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.
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;
- and
- a target unit having a target area facing 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 electron beam guide unit comprises:
- a first portion in a configuration of a truncated cone with a proximal end and a distal end, the distal end having a larger diameter than the proximal end, and
- a second portion in the shape of a hollow cylinder with substantially the same diameter as the proximal end of the truncated cone, and disposed between the proximal end of the truncated cone and the target unit, the second portion being shorter in length than the first portion along an axis of the electron beam guide unit.
