Description

[0002] In some application environments where objects need to be inspected, such as bomb disposal, X-ray image acquisition equipment is required. The X-ray image acquisition equipment is mainly composed of an X-ray source and a detection plate. The object to be inspected is located between the X-ray source and the detection plate. The X-ray source emits X-rays. After the rays penetrate the object to be inspected, they are transmitted to the detection plate, forming an image on the detection plate. The image is transmitted to the computer display via wireless or wired network communication.
