1. An X-ray phase imaging apparatus comprising:
an X-ray source configured to emit X-rays;
an X-ray detector configured to detect the X-rays emitted from the X-ray source;
a plurality of gratings arranged between the X-ray source and the X-ray detector;
an image processor configured to acquire a first X-ray image obtained by imaging a subject according to a set imaging condition and a second X-ray image obtained by imaging without the subject arranged according to the set imaging condition, and generate an X-ray phase contrast image based on the first X-ray image and the second X-ray image;
a storage configured to store the second X-ray image generated by the image processor in association with the imaging condition; and
a control device configured or programmed to:
determine whether or not a decrease in an image quality of the X-ray phase contrast image generated using the second X-ray image stored in the storage, the second X-ray image being associated with the imaging condition of the first X-ray image to be acquired, falls within a predetermined allowable range and/or whether or not the second X-ray image associated with the imaging condition of the first X-ray image to be acquired has been stored in the storage; and
make a notification prompting a user to update or generate the second X-ray image corresponding to the imaging condition of the first X-ray image to be acquired when determining that the decrease in the image quality of the X-ray phase contrast image generated using the second X-ray image associated with the imaging condition of the first X-ray image to be acquired does not fall within the allowable range and/or determining that the second X-ray image associated with the imaging condition of the first X-ray image to be acquired has not been stored in the storage.
