目的：比较锥形束计算机断层扫描（CBCT）三维立体投影图像与直接测量人类颅骨的直线测量的可靠性和准确性。材料与方法：直接测量19个人头骨上标记的24个解剖部位之间的16个线性尺寸。颅骨用CBCT （i-CAT, Imaging Sciences International, Hatfield, Pa）在三种设置下进行成像：(a) 153个投影，(b) 306个投影，(c) 612个投影。将体效果图上地标之间线性测量的平均绝对误差和模态平均值（+/- SD）与使用重复测量的一般线性模型(P
Objective: To compare the in vitro reliability and accuracy of linear measurements between cephalometric landmarks on cone beam computed tomography (CBCT) 3D volumetric images with varying basis projection images to direct measurements on human skulls.Materials and Methods: Sixteen linear dimensions between 24 anatomic sites marked on 19 human skulls were directly measured. The skulls were imaged with CBCT (i-CAT, Imaging Sciences International, Hatfield, Pa) at three settings: (a) 153 projections, (b) 306 projections, and (c) 612 projections. The mean absolute error and modality mean (+/- SD) of linear measurements between landmarks on volumetric renderings were compared to the anatomic truth using repeated measures general linear model (P
