The aim of the study was to assess the technical performance of the system for both configurations. Phantom measurements were performed to assess the accuracy, precision, reproducibility and temporal stability of the system. Translations of the phantom in lateral, longitudinal, and vertical direction, and rotations around three axes (pitch, roll, and yaw) were performed with an accurate, in-house built, positioning stage.本研究旨在评估该系统在两种配置下的技术性能。为评估该系统的准确度、精密度、可重复性与时间稳定性，本次实验开展了体模（phantom）测量。借助一台高精度自研定位平台，对体模完成横向、纵向与垂直方向的平移，以及绕俯仰（pitch）、滚转（roll）、偏航（yaw）三个轴的旋转操作。
