在MIMICS软件中导入保存为DICOM格式的足部数据，调整 CT 灰度阈值，把外围软组织像素提亮，然后重复骨骼重建的步骤建立外围软组织的三维实体模型。提取足部骨骼、软组织建立足部三维模型，导出IGES格式。

Import the foot data saved in DICOM format in MIMICS software, adjust the CT gray threshold, brighten the peripheral soft tissue pixels, and then repeat the steps of bone reconstruction to build the 3D solid model of the peripheral soft tissue. Extract the foot bones and soft tissues to establish the foot 3D model, and export the IGES format.
