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.

First claim

What is claimed is:

1. A mobile X-ray imaging apparatus comprising:
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.

2. The 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 apparatus according to claim 1 , further comprising a switch provided in the supply path of the charging power.

4. The apparatus according to claim 3 , wherein the controller is configured to turn off the switch and block charging of the battery.

5. The apparatus according to claim 1 , wherein the controller is configured to switch the charger to a standby mode and block charging of the battery.

6. The apparatus according to claim 5 , wherein the charger is configured to not generate the charging power in the standby mode.

7. The apparatus according to claim 1 , further comprising an inputter configured to receive an X-ray radiation ready command and an X-ray radiation command,
wherein the controller is configured to block charging of the battery when the X-ray radiation ready command is input.

8. The apparatus according to claim 7 , wherein the controller is configured to perform control such that the charging of the battery is restarted when the radiation command is not input within a predetermined time after the ready command is input.

9. A method of controlling a mobile X-ray imaging apparatus which includes a movable main body, a battery configured to supply operating power to the main body, and a charger configured to supply charging power to charge the battery, the method comprising:
determining whether X-rays are radiated when the charging power is supplied to the battery; and
blocking supply of the charging power to the battery when it is determined that the X-rays are radiated.

10. The method according to claim 9 , wherein, in the mobile X-ray imaging apparatus, a supply path of the operating power and a supply path of the charging power form at least one node.

11. The method according to claim 9 , wherein the mobile X-ray imaging apparatus further includes a switch provided in the supply path of the charging power.

12. The method according to claim 11 , wherein the blocking the supply of the charging power to the battery includes turning off the switch.

13. The method according to claim 9 , wherein the blocking the supply of the charging power to the battery includes switching the charger to a standby mode.

14. The method according to claim 13 , wherein the charger does not generate the charging power in the standby mode.

15. The method according to claim 9 , wherein the determining whether the X-rays are radiated is performed by verifying whether an X-ray radiation ready command is input through an inputter.

16. The method according to claim 15 , further comprising restarting charging of the battery when an X-ray radiation command is not input within a predetermined time after the ready command is input.

17. A mobile X-ray imaging apparatus comprising:
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;
a controller configured to block charging of the battery while X-rays are radiated,
an inputter configured to receive a command,
a switch provided in a supply path of the charging power, wherein when the switch is turned on via the inputter, the supply path of the charging power is disconnected, and when the switch turned off via the inputter, the supply path of the charging power is connected.
