| 摘 要： | ＣＴ机在正常扫描情况下，图象上出现了一簇斜方向伪影。同时屏显ＵＳ００８０错误信息。从提示的错误信息分析，会有许多原因导致ＵＳ００８０信息出现．本文讨论了由于ＧＣＰ信号瞬间丢失而产生的图象伪影。以及修复过程同时也找出了，由于ＢＳＰ内５Ｖ电源低于正常值而产生的图象上有点状伪影的故障原因。

| Abstract: | During CT Scanning there was a normal image in the direction of CCW.However in direction of CW the obliquestrenks appeared and US0080 mistake was showed on the screan.Author found:when the gunery rotated in the direction of CW.GCP single lamp go out for a moment,because GCP single line broke in a twinkling.Aften the line was changed the scanning progress recovered,but there were some white dotted artifacts around the image when SV power in BSP was increased from 4.93 V to 5.03 V,actted artifacts mentioned above disapeared. |
