Abstract

A mobile X-ray imaging apparatus and a method of controlling the mobile X-ray imaging apparatus are provided. The mobile X-ray imaging apparatus includes an X-ray source mounted in a movable main body, a battery configured to supply operating power to the X-ray source, a charger configured to supply charging power to charge the battery, and a controller configured to block charging of the battery while X-rays are radiated.

Claims

1. A mobile X-ray imaging apparatus comprising:

an input device to which a first command and a second command are input, wherein the second command is able to be input after the first command is input;

a battery configured to be charged with charging power;

an X-ray source configured to irradiate X-rays according to operating power supplied from the charged battery; and

a controller configured to block charging of the battery when the first command is input, and to control the battery to supply the operating power to the X-ray source when the second command is input.

2. The mobile X-ray imaging apparatus according to claim 1, wherein a supply path of the operating power and a supply path of the charging power form at least one node.

3. The mobile X-ray imaging apparatus according to claim 2, wherein when the first command is input, the controller blocks the charging power supplied through the supply path of the charging power from entering the supply path of the operating power via the node.

4. The mobile X-ray imaging apparatus according to claim 1, further comprising a switch disposed on the supply path of the charging power.

5. The mobile X-ray imaging apparatus according to claim 4, wherein when the first command is input, the controller turns off the switch to block the supply path of the charging power.

6. The mobile X-ray imaging apparatus according to claim 1, further comprising a charger configured to supply the charging power to the battery in a charging mode, and to stop supplying the charging power to the battery in a standby mode.

7. The mobile X-ray imaging apparatus according to claim 6, wherein when the first command is input, the controller sets the charger to the standby mode to block charging of the battery.

8. The mobile X-ray imaging apparatus according to claim 6, wherein when the first command is not input, the controller sets the charger to the charging mode to charge the battery.

9. The mobile X-ray imaging apparatus according to claim 1, wherein when the second command is not input within a predetermined time period after the first command is input, the controller re-starts charging of the battery.

10. A method of controlling a mobile X-ray imaging apparatus including an input device to which a first command and a second command are input, wherein the second command is able to be input after the first command is input, the method comprising:

charging a battery with charging power when the first command is not input,

blocking charging of the battery when the first command is input; and

supplying operating power to an X-ray source of the mobile X-ray imaging apparatus to irradiate X-rays, when the second command is input.

11. The method according to claim 10, wherein a supply path of the operating power and a supply path of the charging power form at least one node.

12. The method according to claim 11, wherein the blocking of the charging of the battery comprises blocking the charging power supplied through the supply path of the charging power from entering the supply path of the operating power via the node, when the first command is input.

13. The method according to claim 11, wherein the blocking of the charging of the battery comprises blocking charging of the battery using a switch disposed on the supply path of the charging power.

14. The method according to claim 13, wherein the blocking of the charging of the battery comprises turning off the switch, when the first command is input, to block the supply path of the charging power.

15. The method according to claim 10, wherein the mobile X-ray imaging apparatus further comprises a charger configured to supply the charging power to the battery in a charging mode, and to stop supplying the charging power to the battery in a standby mode.

16. The method according to claim 15, wherein the blocking of the charging of the battery comprises setting the charger to the standby mode, when the first command is input, to block charging of the battery.

17. The method according to claim 15, wherein the charging of the battery comprises setting the charger to the charging mode, when the first command is not input, to charge the battery.

18. The method according to claim 10, further comprising re-starting charging of the battery, when the second command is not input within a predetermined time period after the first command is input.
