Abstract：This paper mainly introduced the common false image of CT tube failure, analyzed its causes and basic treatment methods. Taking Siemens CT definition as in our hospital as the research object, 5 cases of common CT ball tube fault artifacts in recent years were collected. Among them, there were 2 cases of artifacts caused by the aging of CT ball tube, 1 case of artifacts caused by the discharge in the tube, 1 case of artifacts caused by the shaking of anode target, and 1 case of artifacts caused by foreign matters in the circulating oil in the tube. The reasons of CT tube malfunction artifact were analyzed deeply, and the artifact was eliminated by changing the tube. In this paper, according to the causes of CT tube malfunction artifact, the corresponding effective corrective measures were proposed to suppress or eliminate the artifact, which also provided relevant clues for equipment maintenance.
