Abstract

Disclosed is an X-ray generation apparatus for intra-oral X-ray imaging, a guide holder, and an X-ray imaging system comprising the same. The X-ray generation apparatus includes a body and a plurality of X-ray sources disposed in different positions of the body, and configured to irradiate X-rays to a field of view, wherein the body moves along a predetermined trajectory for the field of view.

Claims

1. An X-ray generation apparatus for intra-oral X-ray imaging irradiating X-rays to a field of view, the X-ray generation apparatus comprising:

a body; and

a plurality of X-ray sources disposed in different positions of the body, and configured to irradiate X-rays to the field of view,

wherein the body moves along a predetermined trajectory for the field of view, and

wherein each of the X-ray sources includes an X-ray source module, and the X-ray source module is detachably coupled to the body.

2. The X-ray generation apparatus of claim 1, wherein each of the plurality of X-ray sources irradiates X-rays to form a unit frame of X-ray image for the field of view.

3. The X-ray generation apparatus of claim 1, further comprising:

a controller provided in the body, and configured to supply power and control signals for driving the plurality of X-ray sources.

4. The X-ray generation apparatus of claim 3, wherein the body moves along a predetermined trajectory for the field of view, and

the controller drives the plurality of X-ray sources in conjunction with the movement of the body.

5. The X-ray generation apparatus of claim 3, wherein the controller drives the plurality of X-ray sources in conjunction with movement of the plurality of X-ray sources.

6. The X-ray generation apparatus of claim 1, wherein the X-ray source module adopts an electric field emission type nanostructure emitter.

7. The X-ray generation apparatus of claim 1, wherein the plurality of X-ray sources is arranged on the body, and includes a plurality of X-ray source elements adopting an electric field emission type nanostructure emitter, wherein each of the X-ray sources includes at least one X-ray source element.

8. The X-ray generation apparatus of claim 2, wherein the plurality of X-ray sources irradiates the X-rays at a rate of 1 to 20 frames per second.

9. The X-ray generation apparatus of claim 1, further comprising:

a guide holder comprising;

at least two source fasteners disposed outside a subject'"'"'s mouth, and configured to fasten at least two X-ray sources respectively irradiating X-rays;

a sensor fastener disposed inside the subject'"'"'s mouth, and configured to fasten an X-ray sensor apparatus that detects the X-rays irradiated from the respective X-ray sources; and

a loader configured to connect the source fasteners and the sensor fastener.

10. The guide holder of claim 9, wherein the sensor fastener is configured to allow two or more X-ray sensor apparatuses disposed in a back and forth direction with respect to the source fastener to be fastened thereto.

11. An X-ray generation apparatus for intra-oral X-ray imaging irradiating X-rays to a field of view, the X-ray generation apparatus comprising:

a body configured to move along a predetermined trajectory for the field of view;

a plurality of X-ray sources disposed in different positions of the body, and configured to irradiate X-rays to the field of view; and

a guide holder comprising;

at least two source fasteners disposed outside a subject'"'"'s mouth, and configured to fasten at least two X-ray sources respectively irradiating X-rays;

a sensor fastener disposed inside the subject'"'"'s mouth, and configured to fasten an X-ray sensor apparatus that detects the X-rays irradiated from the respective X-ray sources; and

a loader configured to connect the source fasteners and the sensor fastener.
