The geometric error of axial image reconstruction increases with the increase of CT scan slice thickness, due to CT partial volume effect.
重建CT图像的前后方向的几何误差是随着扫描层厚增加而增加，主要是由于CT扫描的部分容积效应影响。
Geometric distortion in 5 different fields of view (FOV) was calculated by measuring the absolute borderline error of direct scan and coronal digital reconstructed radiograph (DRR).
将获得的图像分为不同大小的5个视窗范围，测量直接扫描图像和DRR图像的边界绝对位置误差并计算其几何畸变率。
Error: 451 - Admin rights are required to scan. Scan not performed.
