Abstract

In a radiation imaging apparatus having a radiation generator, an imaging unit including a detecting unit for detecting radiation to generate a radiation image data, a carriage for carrying the radiation generator, and an operating unit for providing an interface to a user, it is decided whether the radiation imaging apparatus is in a moving state or not. When it is decided that the radiation imaging apparatus is in a moving state, the operation function of the operating unit for the radiation detector and the imaging unit is limited.

Claims

1. A radiation imaging apparatus comprising:

a dolly configured to mount and carry a radiation generator, an imaging unit to obtain a radiation image, and an operating unit to provide an interface to a user, wherein the dolly makes the radiation imaging apparatus movable;

an obtaining unit configured to obtain an amount of electric power needed for imaging based on management information including an imaging order; and

a notification unit configured to compare the amount of electric power obtained by the obtaining unit and a remaining amount of charge of a battery for supplying power to the apparatus, and provide notification of a result.

2. The apparatus according to claim 1, wherein said notification unit determines a possible imaging order based on the comparison result out of imaging orders included in the management information, and provides notification of the possible imaging order.

3. A method of controlling a radiation imaging apparatus having a radiation generator, an imaging unit to detect a radiation image data, and a dolly for carrying the radiation generator and the imaging unit, wherein the dolly makes the radiation imaging apparatus movable, the method comprising:

an obtaining step of obtaining an amount of electric power needed for imaging based on management information including an imaging order; and

a notifying step of comparing the amount of electric power obtained in the obtaining step and a remaining amount of charge of a battery for supplying power for the method, and providing notification of a result.

4. The method according to claim 3, wherein in the notifying step, a possible imaging order is determined based on the comparison result out of imaging orders included in the management information, and notification of the possible imaging order is provided.
