| 摘 要： | ＣＴ球管耙偏移是较为少见的，本文以ＧＥ ｓｙｔｅｃ ２０００ｉ为例，详细描述了由此引起的扫描停止，机器伪影等现象及分析、处理过程，并通过与管衰老相比较。进一步述了两者的共同点及在图像质量，管电流稳定性，检测过程等方面的区别，最后总结出一套检测与判断耙心偏移的方法。

| Abstract: | The shift of bull's-eye in CT tube is rare phenomenon today.Something caused by it such as stoppins scan,artifacts of machine and the process of analyzing and managing were described in this paper in detail.Comparing the shift of bull's-ege with the ageing of tube,the author also got the difference between them,for example, the quality of image,the steadiness of tube's current,the process of detecting.At last a method of detecting and judging the shift of bull's-eye correctly was given. |
