1) cupping artifact
杯状伪影
1.
This leads to cupping artifacts in recon- struction image and imaging degradation.
这导致CT图像的退化和杯状伪影的产生。
2) cup-like artifact
"杯状"伪迹
1.
Based on practical experiments,a new method to eliminate beam hardening effect causing cup-like artifacts in CT reconstruction,is demonstrated.
该指数拟合法的误差不到常用的二阶多项式拟合法的1/3,对物体计算层析重构,硬化校正以前有明显的“杯状”伪迹,切片灰度不均匀,用指数法修正以后该伪迹消失,切片灰度均匀。
3) stair-step artifact
梯状伪影
1.

2.
Ring artifact is one of faults of CT scanner frequently.
文章详细地说明了消除环状伪影的过程。
3.
A set of algorithms that enable virtually complete ring artifact correction were proposed.
CT图像环状伪影是由探测器像元响应不理想等因素造成的,它导致CT重建图像的降质,影响了图像的后续处理和量化分析。
5) Circularity artifact
圈状伪影
1.
Circularity artifact comes from the pary of image-data-collecting passage mainly.
圈状伪影多由图像数据采集通道部分产生 ,本文介绍没有维修测试程序时采用的故障排除方法 ,并分析其产生原因。
6) streak artifact
条状伪影
1.
In practice CT reconstruction,when the attenuation coefficients of the material in the reconstructed slice are non-continuous or jumpy changing,for instance,the density of one material is much higher than that of another,the streak artifact in the CT image will be caused.
在CT重建中,当断层射线衰减系数的变化呈非连续性的跳跃变化,如一种材质密度远远大于另一种材质的密度时,CT图像中高密度物质周围就会产生条状伪影。
