SYSTEMS AND METHODS FOR TAKING X-RAY IMAGES

The present disclosure relates to systems and methods for imaging. The method may include: obtaining reference data associated with an object; determining, based on the reference data, at least one of a start point or an end point of an imaging region associated with the object; causing an acquisition device to take an X-ray image of the imaging region based on at least one of the start point or the end point; and transmitting a control signal to cause an indicating device to present at least one of the start point or the end point while taking the X-ray image, wherein the indicating device includes a laser indicating device, the laser indicating device including an emitting unit and a receiving unit, the receiving unit synchronously moving with the emitting unit.
