Abstract
An anode target comprises: a plurality of target structures, used for receiving an electron beam emitted by a cathode to generate a ray, the plurality of target structures being of three-dimensional structures having bevels; a copper cooling body, used for bearing the target structures and comprising an oxygen-free copper cooling body; a cooling oil tube, used for cooling the anode target; and a shielding layer, used for achieving a shielding effect and comprising a tungsten shielding layer. The anode target, the ray light source, the computed tomography scanning device, and the imaging method in the present application are able to enable all target spots on the anode target to be distributed on a straight line, imaging quality of a ray system is improved, and complexity of an imaging system is reduced.
