1. A method, implemented on a computing device having one or more processors and one or more storage media, the method comprising:

causing an X-ray source to emit X-rays to irradiate a subject;

generating an X-ray image of the subject, wherein the X-ray image is generated using a detector that is arranged to face the X-ray source to detect a portion of the X-rays that pass through the subject;

causing to project, using an optical projection device, the X-ray image of the subject on a surface of the subject;

determining one or more adjustment parameters based on the projected X-ray image;

adjusting, based on the one or more adjustment parameters, a position of at least one of the X-ray source or the detector relative to the subject to obtain a second X-ray image; and

causing to project, using the optical projection device, the second X-ray image on the surface of the subject, wherein the second X-ray image includes one or more regions of the subject that are different from one or more regions of the subject included in the X-ray image.
