目的上颌窦的三维（3D）重建，可视化和容积分割寻求使用自动化算法应用到锥形束计算机断层扫描（CBCT）datasets.Materials和方法锥形束计算机断层扫描（CBCT）数据集的三个主题，年龄为9，17，27岁，在3D分割和重建。上颌窦是通过从右窦中的一个起点和左窦中的一个起点传播到两个窦的整个区域而获得的。该过程是基于体素强度分布和常见的解剖结构，特别是每个中鼻道的鼻腔。用C++和VTK语言编写了一个程序来演示上颌窦的表面拓扑形状。结果开发的分割算法成功地分离上颌窦，允许准确的比较。它是强大和有效的。结论利用该方法对CBCT数据进行上颌窦的自动分割是可行的。该工具可能有助于上颌窦疾病的可视化、病理诊断和治疗计划。
Purpose Segmentation of the maxillary sinuses for three-dimensional (3D) reconstruction, visualization and volumetry is sought using an automated algorithm applied to cone beam computed tomographic (CBCT) data sets.Materials and Methods Cone beam computed tomography (CBCT) data sets of three subjects aged 9, 17, and 27 were used in 3D segmentation and reconstruction. The maxillary sinuses were obtained by propagation from one start point in the right sinus and one start point in the left sinus to the whole regions of both sinuses. The procedure was based on voxel intensity distributions and common anatomic structures, specifically each middle meatus of the nasal cavity. A program was written in C++ and VTK languages to demonstrate the surface topological shapes of the maxillary sinuses.Results The developed segmentation algorithm separated maxillary sinuses successfully permitting accurate comparisons. It was robust and efficient. 3D morphological features of the maxillary sinuses were observed from three human subjects.Conclusions Automated segmentation of maxillary sinuses from CBCT data sets is feasible using the proposed method. This tool might be useful for visualization, pathological diagnosis, and treatment planning of maxillary sinus disorders.
