摘要
Abstract
Objective To find fast and accurate methods for reconstructing three-dimensional (3D) model of hip joint after avascular necrosis of femoral head through exploring virtual reality technique. Methods Based on 64 row spiral CT continuous two-dimensional images of hip segments,3D visualization structure of acetabular bone, proximal femur,femoral neck and femoral head ( including cystic area and hardening area) were reconstructed by mimics software. Results Structures of acetabular bone and proximal femur were distinctly displayed by the 3D reconstruction , thereby the diseased tissue can be positioned and its volume can be calculated. Conclusion The application of thinlayer CT and Dicom standard ensures more accurate 3D model of hip joint, providing an objective basis for assessing hip joint after avascular necrosis of femoral head and choosing of treating methods.关键词
