Abstract
Provided is a radiation imaging apparatus, including: an information outputting unit configured to output state information on a state of the radiation imaging apparatus; a correction data acquiring unit configured to acquire offset correction data through use of image data acquired in an acquisition mode that is set based on the state information; and an image processing unit configured to correct image data acquired by imaging an object through use the offset correction data.
Claims15
A radiation imaging apparatus comprising a processor coupled to a storage medium programmed to function as:
- a mode setting unit configured to set an imaging mode for radiation imaging;
- an information outputting unit configured to output state information on a state of the radiation imaging apparatus;
- a correction data acquiring unit configured to acquire offset correction data through use of image data acquired in an acquisition mode;
- an image processing unit configured to correct image data acquired by imaging an object through use of the offset correction data;
- and
- a control unit configured to, when the acquisition mode based on the imaging mode coincides with the acquisition mode based on the state information, control the correction data acquiring unit to acquire the offset correction data in the acquisition mode based on the state information.
A radiation imaging apparatus comprising a processor coupled to a storage medium programmed to function as:
- an information outputting unit configured to output state information on a state of the radiation imaging apparatus including temperature of the radiation imaging apparatus;
- a correction data acquiring unit configured to acquire offset correction data through use of image data acquired in an acquisition mode that is set based on the state information;
- and
- an image processing unit configured to correct image data acquired by imaging an object through use of the offset correction data,
- wherein the information outputting unit is configured to output, as the acquisition mode information based on the state information, an acquisition mode of acquiring the offset correction data through the use of the image data acquired in advance before the imaging of the object, and
- wherein the correction data acquiring unit is configured to acquire the offset correction data based on the acquisition mode.
