## Abstract

An X-ray imaging system including: an X-ray Talbot imaging apparatus which is provided with an object table, an X-ray source, a plurality of gratings, and an X-ray detector side by side in a direction of an X-ray radiation axis, and irradiates the X-ray detector with an X-ray from the X-ray source through an object and the plurality of gratings to obtain a moire image required for forming a reconstruction image of the object; and an object housing inside which the object is housed and an environmental condition independent of an external environment is set, wherein the object housing is provided detachably with respect to the object table.

## Claims

### Claim 1

An X-ray imaging system comprising:
an X-ray Talbot imaging apparatus which is provided with an object table, an X-ray source, a plurality of gratings, and an X-ray detector side by side in a direction of an X-ray radiation axis, and irradiates the X-ray detector with an X-ray from the X-ray source through an object and the plurality of gratings to obtain a moire image required for forming a reconstruction image of the object; and
an object housing inside which the object is housed and an environmental condition independent of an external environment is set,
wherein the object housing is provided detachably with respect to the object table.

### Claim 2 (depends on 1)

The X-ray imaging system according to claim 1,
wherein the X-ray Talbot imaging apparatus includes a hardware processor that causes a series of imaging to acquire the moire image required for forming the reconstruction image of the object, and
wherein the hardware processor of the X-ray Talbot imaging apparatus automatically controls setting of the independent environmental condition inside the object housing in conjunction with the X-ray Talbot imaging apparatus.

### Claim 3 (depends on 1)

The X-ray imaging system according to claim 1, wherein the independent environmental condition includes a condition related to temperature and/or humidity inside the object housing.

### Claim 4 (depends on 1)

The X-ray imaging system according to claim 1, wherein the object housing includes an X-ray transmitter on the X-ray radiation axis and in an X-ray radiation range around the X-ray radiation axis, the X-ray transmitter being less likely to hinder transmission of an X-ray than a peripheral part.

### Claim 5 (depends on 1)

The X-ray imaging system according to claim 1, wherein each of the plurality of gratings is a one-dimensional grating.

### Claim 6 (depends on 5)

The X-ray imaging system according to claim 5, wherein any one of the object table of the X-ray Talbot imaging apparatus and the object housing includes a rotator that rotates the object about the X-ray radiation axis.

### Claim 7 (depends on 1)

The X-ray imaging system according to claim 1, wherein the X-ray Talbot imaging apparatus and the object housing are provided mechanically independently from each other.

### Claim 8 (depends on 7)

The X-ray imaging system according to claim 7, wherein the object housing is provided on the object table of the X-ray Talbot imaging apparatus so as to be movable back and forth with respect to an X-ray radiation range.

### Claim 9 (depends on 1)

The X-ray imaging system according to claim 1, wherein the object housing includes a laser radiator that irradiates the object with a laser beam.

### Claim 10 (depends on 1)

The X-ray imaging system according to claim 1, wherein the object housing includes a nail inserter for performing a nailing test on the object.

### Claim 11 (depends on 1)

The X-ray imaging system according to claim 1, wherein the object housing includes a temperature controllable heat generator that is made to contact the object.
