目的:探讨基于大密度点云数据实现对髋臼前柱置钉通道的全局优化。方法:2022年1月至2023年1月行完整CT扫描成年人正常骨盆CT数据40例,其中男22例,女18例;年龄20～54岁。选取其中3个样本的医学影像数据进行试验研究。规划髋臼前柱置钉通道,针对现行CAD规划方法是否具有先进性的问题,提出了点云获取渠道相同、方向线创建软件各异、三维设计与虚拟试验软件相同的4种组合方法:Mimics+Imageware+UG、Mimics+3DReshaper+UG、Mimics+ZEISS Quality Suite+UG与Mimics+Design X+UG,并依据二次修剪模型的中心点点集和实体点云分别创建方向线,应用于3个髋臼样本左侧前柱置钉通道的规划。以未出现髋臼窝和耻...

OBJECTIVE: To investigate global optimisation of anterior acetabular column pinning channels can be achieved based on large density point cloud data. METHODS: Data were collected on the CT scans of the normal pelvis in 40 adults from January 2022 to January 2023, including 22 males and 18 females, aged 20 to 54 years old. Medical imaging data from three of the samples were selected for experimental study. In planning access for anterior acetabular column pinning, to address the issue of whether the current CAD planning methods were advanced or not, four combinations of the same point cloud acq...
