Abstract
In an X-ray imaging apparatus, an X-ray irradiation unit, an X-ray detection unit, a control unit configured to control irradiation of an X-ray, an X-ray image processing unit configured to operate independently of the control unit, and a storage battery for the X-ray image processing unit and the control unit are provided. The X-ray image processing unit is configured to acquire information on a remaining amount of the storage battery from the control unit and perform processing of reducing power consumption of the X-ray image processing unit when the remaining amount of the storage battery is equal to or less than a predetermined threshold value.
Claims19
An X-ray imaging apparatus comprising:
- an X-ray irradiation unit configured to irradiate an X-ray to a subject;
- an X-ray detection unit configured to detect the X-ray irradiated from the X-ray irradiation unit and has passed through the subject;
- a control unit configured to control irradiation of the X-ray from the X-ray irradiation unit;
- an X-ray image processing unit configured to be operable independently of the control unit and generate an X-ray image based on the X-ray detected by the X-ray detection unit;
- and
- a storage battery configured to supply power to the X-ray image processing unit and the control unit,
- wherein the control unit is configured to acquire information on a remaining amount of the storage battery;
- wherein the X-ray image processing unit is configured to acquire information on the remaining amount of the storage battery from the control unit and perform processing of reducing power consumption of the X-ray image processing unit when an acquired remaining amount of the storage battery is equal to or less than a predetermined threshold value;
- wherein the X-ray image processing unit is configured to, when communication with the control unit becomes unavailable, acquire a non-communication period based on the remaining amount of the storage battery acquired from the control unit immediately before the communication with the control unit becomes unavailable, and perform the processing of reducing the power consumption of the X-ray image processing unit after the non-communication period has elapsed from a point of time when the communication with the control unit becomes unavailable.
An X-ray imaging apparatus comprising:
- an X-ray irradiation unit configured to irradiate an X-ray to a subject;
- an X-ray detection unit configured to detect the X-ray irradiated from the X-ray irradiation unit and has passed through the subject;
- a control unit configured to control irradiation of the X-ray from the X-ray irradiation unit;
- an X-ray image processing unit configured to be operable independently of the control unit and generate an X-ray image based on the X-ray detected by the X-ray detection unit;
- and
- a storage battery configured to supply power to the X-ray image processing unit and the control unit;
- a notification unit configured to notify that the remaining amount of the storage battery has decreased when the remaining amount of the storage batter received from the control unit by the X-ray image processing unit has become equal to or less than the predetermined threshold value;
- wherein the control unit is configured to acquire information on a remaining amount of the storage battery;
- wherein the X-ray image processing unit is configured to acquire information on the remaining amount of the storage battery from the control unit and perform processing of reducing power consumption of the X-ray image processing unit when an acquired remaining amount of the storage battery is equal to or less than a predetermined threshold value
- and wherein the X-ray image processing unit is configured to perform the processing of reducing the power consumption of the X-ray image processing unit after a post-notification period has elapsed after performing a notification by the notification unit.
