Abstract
An X-ray phase imaging apparatus includes an X-ray source; a detector; a plurality of gratings; an image processor configured to generate two or more types of first phase contrast images selected from absorption, differential phase and dark-field images as preview images under an imaging condition simpler than an imaging condition for a second phase contrast image to be captured in actual imaging; and a controller configured to display the first phase contrast images on a display.
Claims8
An X-ray phase imaging apparatus comprising:
- an X-ray source configured to irradiate a subject with X-rays;
- 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;
- an image processor configured to generate two or more types of first phase contrast images selected from absorption, differential phase and dark-field images as preview images based on image signals of the subject produced by the X-ray source and the detector under an imaging condition simpler than an imaging condition for a second phase contrast image to be captured in actual imaging;
- wherein the image processor is configured to generate as the second phase contrast image a phase contrast image that corresponds to a type selected by a user from the types of the first phase contrast images, which can be seen by the user, and is captured under the imaging condition for the actual imaging;
- and
- a controller configured to display the first phase contrast images generated by the image processor on a display.

A display method of a preview image in an X-ray phase imaging apparatus comprising:
- a step of generating two or more types of first phase contrast images selected from absorption, differential phase and dark-field images as preview images based on image signals of a subject produced by an X-ray source and a detector under an imaging condition simpler than an imaging condition for a second phase contrast image to be captured in actual imaging;
- a step of displaying the generated first phase contrast images on a display;
- and
- generating as the second phase contrast image a phase contrast image that corresponds to a type selected by a user from the types of the first phase contrast images, which can be seen by the user, and is captured under the imaging condition for the actual imaging.
