Abstract
An X-ray phase imaging apparatus includes an X-ray source; a detector; a plurality of gratings; a rotation mechanism; an image processor configured to generate a phase contrast image and to generate a preview image prior to capture of the phase contrast image; and a controller configured to control function of displaying on a display the preview image, and function of discriminatively displaying on the display an image coverage area for the phase contrast image that is associated with a relative rotation angle between the plurality of gratings and a subject.

An X-ray phase imaging apparatus comprising:
- an X-ray source;
- a detector configured to detect X-rays radiated from the X-ray source;
- a plurality of gratings arranged between the X-ray source and the detector;
- a rotation mechanism configured to rotate the plurality of gratings and a subject relative to each other in a plane orthogonal to an optical axis direction of the X-rays;
- an image processor configured to generate a phase contrast image based on a detection signal generated by the X-ray source and the detector, and to generate a preview image based on the detection signal generated by the X-ray source and the detector prior to capture of the phase contrast image;
- and
- a controller configured to control function of displaying on a display the preview image generated by the image processor, and function of discriminatively displaying on the display an image coverage area for the phase contrast image that is associated with a relative rotation angle between the plurality of gratings and the subject.
A display method of a preview image in an X-ray phase imaging apparatus including an X-ray source, a detector and a plurality of gratings, the method comprising:
- a step of generating a preview image based on a detection signal generated by the X-ray source and the detector prior to capture of a phase contrast image;
- a step of displaying the preview image on a display;
- and
- a step of discriminatively displaying on the display in the preview image an image coverage area for the phase contrast image that is associated with a relative rotation angle between the plurality of gratings and a subject.
