Abstract
Disclosed is an X-ray Talbot imaging apparatus for nondestructive inspection, the apparatus including: a radiation source; a subject table; a plurality of gratings; and a radiation detector. The radiation source, the subject table, the plurality of gratings, and the radiation detector are provided in order side by side in a radiation irradiation axis direction, the plurality of gratings include at least a first grating and a second grating in order from a grating close to the subject table, and an object that absorbs visible light is placed between the first grating and a subject.
Claims13
An X-ray Talbot imaging apparatus for nondestructive inspection, the apparatus comprising:
- a radiation source;
- a subject table;
- a plurality of gratings;
- and
- a radiation detector, wherein
- the radiation source, the subject table, the plurality of gratings, and the radiation detector are provided in order side by side in a radiation irradiation axis direction,
- the plurality of gratings include at least a first grating and a second grating in order from a grating close to the subject table, and
- an object that absorbs visible light is placed between the first grating and a subject.
An imaging method using a nondestructive inspection X-ray Talbot imaging apparatus in which a radiation source, a subject table, a plurality of gratings, and a radiation detector are arranged in order side by side in a radiation irradiation axis direction, wherein the plurality of gratings include at least a first grating and a second grating in order from a grating close to the subject table, and an object that absorbs visible light is placed between the first grating and a subject, the method comprising:
- causing the radiation source to irradiate the subject arranged in the radiation irradiation axis direction with radiation;
- and
- generating at least a small-angle scattering image and/or a differential phase image of the subject based on a moire fringe image obtained by irradiation.
