Abstract

An X-ray imaging apparatus includes an X-ray detecting device, an accommodation unit configured to accommodate the X-ray detecting device, and a bucky tray configured to be accommodated in and discharged from the accommodation unit. The bucky tray includes a base and a first plate on which the X-ray detecting device is mounted and which is configured to rotate with respect to the base.

First claim

What is claimed is:

1. An X-ray imaging apparatus comprising:
an X-ray detecting device;
a bucky tray on which the X-ray detecting device is configured to be mounted; and
an accommodation unit configured to accommodate the bucky tray,
wherein the bucky tray configured to be accommodated in or discharged from the accommodation unit and comprises:
a base,
a first plate on which the X-ray detecting device is mounted and which is configured to be rotatable with respect to the base between a first position and a second position, and
a rotation plate which is coupled to the first plate, and comprises a slide rail formed along a cylindrical direction of the rotation plate,
wherein the base comprises a guide which is provided thereon and configured to be inserted into the slide rail.

2. The X-ray imaging apparatus of claim 1 , wherein the rotation plate is positioned between the first plate and the base and rotatable together with the first plate.

3. The X-ray imaging apparatus of claim 1 , wherein a center of the rotation plate is eccentric with respect to a center of the base.

4. The X-ray imaging apparatus of claim 1 , wherein a center of the rotation plate matches a center of the base.

5. The X-ray imaging apparatus of claim 1 , further comprising one or more rotation sensors configured to sense a rotation position of the rotation plate after the rotation plate is rotated.

6. The X-ray imaging apparatus of claim 5 , wherein the one or more rotation sensors comprise:
a first rotation sensor; and
a second rotation sensor arranged apart from each other by a predetermined distance along the cylindrical direction of the rotation plate.

7. The X-ray imaging apparatus of claim 6 , wherein each of the first rotation sensor and the second rotation sensor includes an optical encoder or a magnetic encoder.

8. The X-ray imaging apparatus of claim 5 , further comprising:
a controller configured to receive, from the one or more rotation sensors, a sensing signal indicating an arrangement location of the X-ray detecting device based on the rotation position of the rotation plate and transmit a control signal regarding a size of an X-ray exposure area to an X-ray emitter.

9. The X-ray imaging apparatus of claim 1 , further comprising:
a detachment sensor configured to sense whether the X-ray detecting device is attached to or detached from the bucky tray.

10. The X-ray imaging apparatus of claim 1 , wherein the X-ray detecting device comprises a first terminal, and
the first plate comprises a second terminal connected to the first terminal to connect the X-ray detecting device to an external device.

11. The X-ray imaging apparatus of claim 1 , wherein the X-ray detecting device is wirelessly connected to an external device.

12. The X-ray imaging apparatus of claim 1 , further comprising:
location guides, some of which are configured to guide a location of the X-ray detecting device such that a center of the bucky tray matches a center of the X-ray detecting device.

13. An X-ray imaging apparatus comprising:
an X-ray detecting device;
a bucky tray on which the X-ray detecting device is configured to be mounted; and
an accommodation unit configured to accommodate the bucky tray,
wherein the bucky tray is configured to be accommodated in or discharged from the accommodation unit and comprises:
a base,
a first plate on which the X-ray detecting device is mountable, and
a second plate configured to be coupled to the first plate to be movable to at least one of a first location where the X-ray detecting device of a first size is accommodated and a second location where another X-ray detecting device of a second size is accommodated.

14. The X-ray imaging apparatus of claim 13 , wherein the second plate is configured to slide with respect to the first plate, to the first and second locations.

15. The X-ray imaging apparatus of claim 13 , wherein the first plate and the second plate are configured to symmetrically slide.

16. The X-ray imaging apparatus of claim 15 , wherein the bucky tray further comprises:
a middle plate positioned between the first plate and the base;
a pinion gear positioned on the middle plate; and
a pair of rack gears respectively positioned on the first plate and the second plate and interlocked to the pinion gear.

17. The X-ray imaging apparatus of claim 13 , further comprising a slide fastener configured to fasten the second plate in the first and second locations.

18. The X-ray imaging apparatus of claim 13 , wherein the X-ray detecting device comprises a first terminal and the second plate comprises a second terminal connected to the first terminal.

19. The X-ray imaging apparatus of claim 13 , further comprising:
location guides configured to guide a location of the X-ray detecting device such that a center of the bucky tray matches a center of the X-ray detecting device,
wherein at least one of the location guides is provided on the second plate.

20. The X-ray imaging apparatus of claim 13 , further comprising one or more rotation sensors configured to sense a rotation position of the rotation plate after the rotation plate is rotated.

21. The X-ray imaging apparatus of claim 20 , wherein the one or more rotation sensors comprise:
a first rotation sensor; and
a second rotation sensor arranged apart from each other by a predetermined distance along the cylindrical direction of the rotation plate.

22. The X-ray imaging apparatus of claim 20 , further comprising:
a controller configured to receive, from the one or more rotation sensors, a sensing signal indicating an arrangement location of the X-ray detecting device based on the rotation position of the rotation plate and transmit a control signal regarding a size of an X-ray exposure area to an X-ray emitter.

23. The X-ray imaging apparatus of claim 13 , the first plate and the second plate are configured to be rotatable with respect to the base.

24. The X-ray imaging apparatus of claim 13 , wherein the bucky tray further comprises:
a middle plate positioned between the base and one of the first plate and the second plate;
a rotation axis positioned on the middle plate;
a pair of slide rails disposed on opposite sides apart from the rotation axis; and
a pair of guides respectively positioned on the first plate and the second plate,
wherein the pair of slide rails is configured to be rotatable with respect to the rotation axis, and
the pair of guides is configured to respectively move in the pair of slide rails.

25. The X-ray imaging apparatus of claim 13 , further comprising:
