Patient-specific cranial implants are important and necessary in the surgery of cranial defect restoration. However, traditional methods of manual design of cranial implants are complicated and time-consuming. Our purpose is to develop a novel software named EasyCrania to design the cranial implants conveniently and efficiently. The process can be divided into five steps, which are mirroring model, clipping surface, surface fitting, the generation of the initial implant and the generation of the final implant. The main concept of our method is to use the geometry information of the mirrored model as the base to generate the final implant. The comparative studies demonstrated that the EasyCrania can improve the efficiency of cranial implant design significantly. And, the intra- and inter-rater reliability of the software were stable, which were 87.07 ± 1.6% and 87.73 ± 1.4% respectively.
个体化颅骨植入物在颅骨缺损修复手术中非常重要且必不可少。然而，传统的颅骨植入物手动设计方法既复杂又耗时。我们的目的是开发一种名为 EasyCrania 的新型软件，以便于高效地设计颅骨植入物。该过程可以分为五个步骤，即镜像模型、裁剪曲面、曲面拟合、初始植入物的生成和最终植入物的生成。我们方法的主要理念是使用镜像模型的几何信息作为基础来生成最终植入物。对比研究表明，EasyCrania 可以显著提高颅骨植入物设计的效率。此外，该软件的组内和组间信度稳定，分别为 87.07 ± 1.6%和 87.73 ± 1.4%。
