Abstract
A radiography control apparatus includes an acquisition unit configured to acquire data of image-capturing mode and a change unit configured to change the number of times a correction image is captured, the correction image being used to correct a radiographic image in accordance with the acquired image-capturing-mode data.
Claims17
A radiography control apparatus, comprising:
- an acquisition unit configured to acquire data of image-capturing mode;
- and
- a change unit configured to change a number of correction images which are to be captured, the correction image being used to correct a radiographic image in accordance with the acquired image-capturing-mode data.
A radiography control apparatus comprising:
- an acquisition unit configured to acquire data of image-capturing mode;
- and
- a change unit configured to change a number of correction images which are to be captured, the correction image being used to correct a radiographic image in accordance with the acquired image-capturing-mode data, wherein
- the image-capturing mode indicates at least one of a dose of radiation, one type of the radiography indicating static-image capturing or moving-image capturing, one type of the correction image indicating a correction image used for the static-image capturing or a correction image used for the moving-image capturing, a frame rate, whether addition reading is performed, whether a grid is used, and a distance between a radiation source and an image-pickup unit.

A radiography control apparatus comprising:
- an acquisition unit configured to acquire data of image-capturing mode;
- and
- a change unit configured to change a number of correction images which are to be captured, the correction image being used to correct a radiographic image in accordance with the acquired image-capturing-mode data, wherein the change unit sets a target precision used to determine whether a value of a statistic indicating at least one random noise of the correction image reaches a target value used to correct the radiographic image based on the image-capturing mode, and controls a radiographic apparatus to acquire the correction image until the statistic value reaches a value of the target precision.
A radiography control method comprising:
- acquiring data of image-capturing mode when the radiographic apparatus performs the radiography;
- changing a number of correction images which are to be captured;
- and
- correcting a radiographic image in accordance with the acquired image-capturing-mode data.
