本研究的目的是调查TracerCAD系统在测量已知尺寸和体积的模型的准确性。制备了圆柱形尼龙6.6模型。添加了标志以指示近端、远端、前部、内侧和外侧。沿着圆柱体的长度以规则的间隔沿着添加四个额外的标志，以计算相对于这些标志的直径和体积。使用保证精度为0.01 mm的比较仪测量模型，并使用TracerCAD系统进行跟踪（试验1）。将模型旋转90度重复测试（测试2），以确定是否存在与模型相对于发送器的方向相关的任何影响。测量结果和TracerCAD扫描之间的平均体积差异在0.20%和-1.96%之间。单个痕量体积在-0.0085%和-4.50%之间变化。在测试1和2中测量的所有体积中，测量的所有最大体积百分比差异均大于3%。
The objective of this study is to investigate the accuracy of the TracerCAD system in measuring a model of known dimensions and volumes. A cylindrical nylon 6.6 model was prepared. Landmarks were added to indicate proximal, distal, anterior, medial, and lateral. Four additional landmarks were added at regular intervals along the length of the cylinder with a view to calculating diameters and volumes relative to these landmarks. The model was measured using a comparator with a guaranteed accuracy of 0.01 mm and was traced using the TracerCAD system (Test 1). The test was repeated with the model rotated by 90 degrees (Test 2), to determine whether there were any effects related to the orientation of the model in relation to the transmitter. The difference in average volume between measured results and TracerCAD scans was between 0.20% and -1.96%. Individual trace volumes varied between - 0.0085% and -4.50%. In all volumes measured in Tests 1 and 2, all maximum volume percentage differences measured greater than 3%.
