Abstract

An X-ray inspection device includes an X-ray generator, a two-dimensional X-ray detector arranged so as to sandwich subjects between the X-ray detector and the X-ray generator, and a plurality of rotating tables on which the subjects are placed. The rotating tables are arranged at positions where radiographic images of the subjects are projected onto the X-ray detector in a state of not overlapping with each other, and at the time of inspecting the subjects, the rotating tables rotate simultaneously, the X-ray detector sequentially acquires a plurality of X-ray images in which the radiographic images appear, and a controller connected to the X-ray detector generates CT images of the respective subjects on the basis of the X-ray images.

Claims

1-3. -3. (canceled)

4. An X-ray inspection device comprising:

an X-ray generator configured to irradiate a plurality of subjects with X-rays;

a two-dimensional X-ray detector arranged so as to sandwich the subjects between the X-ray detector and the X-ray generator;

a plurality of rotating tables on which each of the subjects is placed; and

a controller connected to the X-ray detector, wherein

the rotating tables are arranged at positions where radiographic images of the respective subjects are projected onto the X-ray detector in a state of not overlapping with each other, and

at a time of inspecting the subjects, the rotating tables are configured to rotate simultaneously, the X-ray detector is configured to acquire in sequence a plurality of two-dimensional X-ray images in which the radiographic images of the subjects appear, and the controller is configured to generate computed tomography (CT) images of the respective subjects on a basis of the acquired X-ray images, and

the controller is configured, when generating the CT image of a single subject on a basis of the acquired X-ray images, to generate the CT image by performing a predetermined calculation using, in each of the X-ray images, only a portion including the radiographic image of the single subject for which the CT image is generated.

5. An X-ray inspection device comprising:

an X-ray generator configured to irradiate a plurality of subjects with X-rays;

a two-dimensional X-ray detector arranged so as to sandwich the subjects between the X-ray detector and the X-ray generator;

a plurality of rotating tables on which each of the subjects is placed; and

a controller connected to the X-ray detector, wherein

the rotating tables are arranged at positions where radiographic images of the respective subjects are projected onto the X-ray detector in a state of not overlapping with each other, and

at a time of inspecting the subjects, the rotating tables are configured to rotate simultaneously, the X-ray detector is configured to acquire in sequence a plurality of two-dimensional X-ray images in which the radiographic images of the subjects appear, and the controller is configured to generate computed tomography (CT) images of the respective subjects on a basis of the acquired X-ray images, and

the controller is configured, when generating the CT image of a single subject on a basis of the acquired X-ray images, to generate the CT image by cutting out, in each of the X-ray images, a portion including the radiographic image of the single subject for which the CT image is generated and performing a predetermined calculation using only the cutout portion.
