IMAGING AREA SPECIFYING APPARATUS, RADIOGRAPHIC SYSTEM, IMAGING AREA SPECIFYING METHOD, RADIOGRAPHIC APPARATUS, AND IMAGING TABLE
First Claim
1. An imaging area specifying apparatus comprising:
- a storage component that stores as correlation information a correlation value correlated with the amount of radiation emitted to each of a plurality of predetermined areas divided from a detection region of a radiation detector that outputs an electric signal indicating a radiological image represented by radiation which is emitted to the detection region for detecting the radiation; and
a specifying component that specifies an imaging area capable of capturing the radiological image of a predetermined size while preventing variations in the amount of radiation emitted to each of the divided areas in the detection region, on the basis of the correlation information stored in the storage component.

Abstract
An imaging area specifying apparatus that includes a storage component and a specifying component is provided. The storage component stores as correlation information a correlation value correlated with the amount of radiation emitted to each of a plurality of predetermined areas divided from a detection region of a radiation detector that outputs an electric signal indicating a radiological image represented by radiation which is emitted to the detection region for detecting the radiation. The specifying component specifies an imaging area capable of capturing the radiological image of a predetermined size while preventing variations in the amount of radiation emitted to each of the divided areas in the detection region, on the basis of the correlation information stored in the storage component.
