Drill Tracking Accuracy Results.

This table displays results for four separate tracking accuracy experiments on the cylinder and ball phantom in the operating room. Average target registration errors are given in millimeters for the “Pointer” and a drill with “3 mm”, “4 mm” or “5 mm” drill bits attached, for each experiment. Additionally, overall average and maximum target registration errors for each of the instruments are displayed in millimeters in the row “Average” and “Maximum” respectively. “SD” means standard deviation.

本表格展示了手术室环境下针对圆柱与球模体（cylinder and ball phantom）开展的四组独立跟踪精度实验结果。针对每组实验，均给出了「Pointer」工具以及装配有3mm、4mm、5mm钻头的电钻的平均靶配准误差（target registration error），单位为毫米。此外，表格的「Average」行与「Maximum」行分别展示了各器械的总体平均靶配准误差与最大靶配准误差，单位均为毫米。其中「SD」代表标准差（standard deviation）。
