Anode target, ray light source, computed tomography device, and imaging method

A computer tomography device, comprising:

• a distributed ray light source comprising:
• cathode assemblies, configured to emit electron beams;
• an anode assembly, configured to receive the electron beams from the cathode assemblies and generate a ray light source;
• wherein the anode assembly includes an anode target, the anode target including:
• a first anode target, configured to cause, by a first voltage carried thereon, electron beams emitted from the cathode assemblies to generate first rays on target spots of the first anode target;
• a second anode target, configured to cause, by a second voltage carried thereon, the electron beams emitted from the cathode assemblies to generate second rays on target spots of the second anode target;
• and
• a metallized ceramic body, configured to isolate the first anode target from the second anode target, wherein the metallized ceramic body is connected to both the first anode target and the second anode target and is provided between the first anode target and the second anode target, and the first anode target, the second anode target and the metallized ceramic body are gold-copper welded and integrated into one entity;
• wherein the first anode target and the second anode target are each of a strip shape, the anode assembly including the first anode target and the second anode target is provided in the same plane as the cathode assemblies arranged on two sides of the anode assembly, and the cathode assemblies arranged on one side of the anode target facing the first anode target are arranged to be staggered with the cathode assemblies arranged on the other side of the anode target facing the second anode target;
• and
• an imaging device, configured to perform ray imaging with the first rays and the second rays.
