Current radiotherapy planning procedures are generally designed based on anatomical information only and use computed tomography (CT) images that do not incorporate organ‐functional information. In this study, we developed a method for estimating liver elasticity using the finite element method (FEM) and four‐dimensional CT (4DCT) images acquired during radiotherapy planning, and we subsequently evaluated its feasibility as a biomarker for liver fibrosis.

使用有限元方法和三维计算机断层扫描图像作为肝纤维化的生物标志物，估计肝脏弹性

当前的放射治疗计划程序通常仅基于解剖学信息设计，并使用不包含器官功能信息的计算机断层扫描（CT）图像。在这项研究中，我们开发了一种使用放射治疗计划期间获得的有限元方法（FEM）和二维CT（4DCT）图像估算肝脏弹性的方法，随后我们评估了其作为肝纤维化生物标志物的可行性。
