Abstract

An X-ray apparatus includes an X-ray radiator configured to radiate an X-ray, and a controller acquiring orientation information of the X-ray radiator and orientation information of at least one X-ray detector, selecting the at least one X-ray detector based on the orientation information of the X-ray radiator and the orientation information of the at least one X-ray detector, and determining a power mode of the selected X-ray detector to be a power consumption mode and a power mode of an X-ray detector that is not selected, to be a power save mode.

First claim

What is claimed is:

1. An X-ray apparatus comprising:
an X-ray radiator configured to radiate an X-ray; and
a controller configured to:
acquire orientation information of the X-ray radiator including information indicating an X-ray radiation direction of the X-ray radiator and orientation information of a plurality of X-ray detectors,
select an X-ray detector of the plurality of X-ray detectors based on the orientation information of the X-ray radiator including the information indicating the X-ray radiation direction of the X-ray radiator and the orientation information of the plurality of X-ray detectors, and
set a power mode of the selected X-ray detector to be a power consumption mode and a power mode of an unselected X-ray detector of the plurality of X-ray detectors to be a power save mode.

2. The X-ray apparatus of claim 1 , wherein, when at least one X-ray detector of the plurality of X-ray detectors is coupled to a receptor, the controller is further configured to set a power mode of the receptor to be the same as a power mode of the at least one X-ray detector that is coupled to the receptor.

3. The X-ray apparatus of claim 1 , wherein the controller is further configured to acquire the orientation information of the X-ray radiator based on a positioning mode of the X-ray apparatus, the positioning mode being one of a stand mode, a table mode, and a portable mode.

4. The X-ray apparatus of claim 1 , wherein, when a non-usage time of the X-ray apparatus exceeds a threshold time, the controller is further configured to switch an operation mode of the X-ray apparatus to a sleep mode and to adaptively set the threshold time.

5. The X-ray apparatus of claim 4 , wherein the controller is further configured to:
acquire a usage time distribution function that is a frequency of using the X-ray apparatus with respect to a time interval between scanning operations performed by the X-ray apparatus,
acquire a utility function based on the usage time distribution function, and
set a time to maximize the utility function as the threshold time.

6. The X-ray apparatus of claim 4 , further comprising a collimator that comprises a blade configured to block the X-ray and a blade driver configured to move the blade,
wherein the controller is further configured to control the blade driver to move the blade to a first reference position and obtain a first relative position of the blade with respect to the first reference position until the operation mode is switched to the sleep mode.

7. The X-ray apparatus of claim 6 , wherein, when the operation mode is switched to the sleep mode and then to a use mode, the controller is further configured to control the blade driver to move the blade to the first reference position and control the blade driver to move the blade by the first relative position from the first reference position.

8. The X-ray apparatus of claim 7 , further comprising a plurality of filters configured to filter the X-ray and a filter driver configured to move the plurality of filters, wherein the controller is further configured to:
control the filter driver to move the plurality of filters to second reference positions and obtain second relative positions of the plurality of filters with respect to the second reference positions until the operation mode is switched to the sleep mode, and
when the operation mode is switched to the sleep mode and then to a use mode, control the filter driver to move the plurality of filters to the second reference positions and control the filter driver to move the plurality of filters by the second relative positions from the second reference positions.

9. The X-ray apparatus of claim 4 , further comprising a mode indicator configured to indicate that the operation mode of the X-ray apparatus is the sleep mode.

10. The X-ray apparatus of claim 9 , wherein:
the mode indicator comprises a light-emitting element, and
when the operation mode of the X-ray apparatus is the sleep mode, the light-emitting element is configured to flicker at a speed equal to or less than a predetermined speed.

11. A workstation comprising:
a communicator configured to receive orientation information of an X-ray radiator including information indicating an X-ray radiation direction of the X-ray radiator and orientation information of a plurality of X-ray detectors; and
a controller configured to:
select an X-ray detector of the plurality of X-ray detectors based on the orientation information of the X-ray radiator including the information indicating the X-ray radiation direction of the X-ray radiator and the orientation information of the plurality of X-ray detectors, and
set a power mode of the selected X-ray detector to be a power consumption mode and a power mode of an unselected X-ray detector of the plurality of X-ray detectors to be a power save mode.

12. The workstation of claim 11 , wherein, when at least one X-ray detector of the plurality of X-ray detectors is coupled to a receptor, the controller is further configured to set a power mode of the receptor to be the same as a power mode of the at least one X-ray detector that is coupled to the receptor.

13. The workstation of claim 11 , wherein the controller is further configured to acquire the orientation information of the X-ray radiator based on a positioning mode of the X-ray apparatus, the positioning mode being one of a stand mode, a table mode, and a portable mode.

14. The workstation of claim 11 , wherein, when non-usage times of the X-ray apparatus and the workstation exceed a threshold time, the controller is further configured to switch an operation mode of the X-ray apparatus and the workstation to a sleep mode and to adaptively set the threshold time.

15. The workstation of claim 14 , wherein the controller is further configured to:
acquire a usage time distribution function that is a frequency of using the X-ray apparatus with respect to a time interval between scanning operations performed by the X-ray apparatus,
acquire a utility function based on the usage time distribution function, and
set a time to maximize the utility function as the threshold time.

16. The workstation of claim 14 , wherein the X-ray apparatus further comprises a collimator that comprises a blade configured to block an X-ray radiated from the X-ray radiator and a blade driver configured to move the blade, and
wherein the controller is further configured to control the blade driver to move the blade to a first reference position and obtain a first relative position of the blade with respect to the first reference position until the operation mode is switched to the sleep mode.

17. The workstation of claim 16 , wherein, when the operation mode is switched to the sleep mode and then to a use mode, the controller is further configured to control the blade driver to move the blade to the first reference position and control the blade driver to move the blade by the first relative position from the first reference position.
