BACKGROUND: With the improvement of medical imaging technology, the visualization of human anatomy has been further developed; the role of three-dimensional (3D) reconstruction in medical treatment is also becoming increasingly prominent. Mimics is the most widely used medical image reconstruction software. Arigin 3D Pro is a recently developed 3D reconstructed medical software system based on 3D printing. OBJECTIVE: To study the accuracy of 3D reconstruction models obtained by using Arigin 3D Pro and Mimics with medical images. METHODS: The image data of liver, spine, knee joint and heart were selected, and the deviations of two software reconstruction models were analyzed based on the 3D model reconstructed by Mimics. Totally 10 cases of skull and 1 case of femoral comminuted fracture image data were selected and reconstructed. Each reconstruction model was measured with 10 groups of feature sizes to evaluate the differences between the two software programs. RESULTS AND CONCLUSION: Arigin 3D Pro and Mimics were used to reconstruct the liver, spine, knee and heart data. The mean ± standard deviation of model deviations were (0.93 ± 1.05), (0.36 ± 0.74), (0.45 ± 0.74), (0.18 ± 0.41) mm. It took 3 minutes and 35 minutes for Arigin 3D Pro and Mimics to reconstruct the liver model respectively, and both software reconstructed other models for less than 1 minute. There was no statistically significant difference between the feature sizes of the two software for the 3D reconstruction models of skull and femoral comminuted fracture data (P > 0.05). The 3D reconstruction model of Arigin 3D Pro is comparable to that of Mimics. For the liver model, the reconstructed time of Arigin 3D Pro is significantly shorter than that of Mimics.%背景:随着医学成像技术不断提高,人体解剖结构的可视化研究得到进一步发展,三维重建技术在医疗方面的作用也逐渐凸显.Mimics是目前应用最为广泛的医学图像三维重建软件,Arigin 3D Pro则是近期国内自主研发的一款基于3D打印的医学重构软件系统.目的:探讨Arigin 3D Pro软件和Mimics软件在医学图像三维重建处理中的精确度.方法:选取肝脏、脊柱、膝关节、心脏部位的图像数据,以Mimics软件重构后的3D模型为依据,进行两款软件重构模型的偏差分析;选取10例头颅部位及1例股骨粉碎性骨折的图像数据,进行三维重建,对每个重建模型均进行10组特征尺寸的测量,评估两款软件重构模型特征尺寸的差异.结果与结论:Arigin 3D Pro和Mimics软件对肝脏、脊柱、膝关节、心脏的三维重建模型,偏差的均值±标准差分别为(0.93±1.05),(0.36±0.74),(0.45±0.74)及(0.18±0.41) mm.Arigin 3D Pro和Mimics软件重建肝脏模型的时间分别为3 min、35 min,两款软件重建其他模型的时间均小于1 min.对于头颅、股骨粉碎性骨折的3D重构模型,两款软件Arigin 3D Pro软件与Mimics差异无统计学意义(P均> 0.05).说明Arigin 3D Pro软件与Mimics软件3D重构模型的精度相当,对于肝脏模型而言,Arigin 3D Pro软件的重建时间明显优于Mimics软件.
