Classification: CPC A  G | IPC A  G

Claim 0:
1. An X-ray imaging device that obtains imaging information indicating an internal structure of an imaging object by using intensity of X-rays transmitted through the imaging object, comprising:
an X-ray source that emits the X-rays toward the imaging object;
an X-ray intensity measurement unit that is disposed to face the X-ray source with the imaging object interposed therebetween, and obtains intensity information of the X-rays transmitted through the imaging object;
a distance measurement unit that irradiates the imaging object with measurement light reflected from a surface of the imaging object, and obtains distance information to the surface of the imaging object by using the measurement light reflected from the surface of the imaging object; and
an information processing unit that obtains the imaging information by using the intensity information and the distance information,
wherein the information processing unit includes,
an extraction unit that extracts information used in generation of the imaging information from a plurality of pieces of the intensity information by using at least the distance information, and
an image generation unit that generates the imaging information by using the intensity information extracted in the extraction unit, and
the extraction unit includes,
a distance difference acquisition unit that acquires a distance difference between first distance information acquired at a first timing and second distance information acquired at a second timing,
a distance evaluation unit that evaluates whether or not the distance difference is within an allowable range, and outputs first permission information when the distance difference is within the allowable range, and
a labelling unit that applies information indicating use for generation of the imaging information to the intensity information acquired at the second timing when the output of the distance evaluation unit is the first permission information.
