The objective of this study was to compare the performance of six validated brain finite element (FE) models to localized brain motion validation data in five experimental configurations. Model performance was measured using the objective metric CORA (CORrelation and Analysis), where higher ratings represent better correlation. The KTH model achieved the highest average CORA rating, and the ABM received the highest average rating among models robustly validated against five cadaver impacts in three directions. This technique can be more frequently employed to build better models and, when associated limitations are well understood, to compare inter-model performance under similar conditions.
本研究的目的是在五种实验配置下，将六个经过验证的脑有限元（FE）模型的性能与局部脑运动验证数据进行比较。使用客观指标CORA（相关性和分析）来衡量模型性能，评分越高表示相关性越好。KTH模型获得了最高的平均CORA评分，而ABM在针对三个方向的五次尸体撞击进行了充分验证的模型中获得了最高的平均评分。当能够充分理解相关限制时，这种技术可以更频繁地用于构建更好的模型，并在相似条件下比较模型间的性能。
