摘要
Abstract
Images corresponded to the right knee of a 27 years old, healthy, male volunteer, weighing 68 Kg, 175 cm height, with no knee joint disease, were selected. The scanning was performed using 1.5T Twinspeed/Excite magnetic resonance tomography. The image was uninterrupted sagittal planes picture, and the scanning way was from the inside to out. The three-dimensional tibia-femoral joint model was established by the MR1 images after they were handled by correlation analysis software (Mimics10.0, Geomagic Studio 8.0). At last, transformed the model format STL file to IGS file, which can be acceptable by analysis software 11.0. On the base of this way, a highly simulation tibia-femoral model was established. It provides a guarantee for the further finite element analysis concerning checking the surface of femoral condyle cartilage to repair interphalangeal joint injuries. The result demonstrated that 3-D computer model established by using 2-D MRI pictures makes up the CT scanning deficiencies on soft tissue, which confirms the model closer to the real anatomical structure.关键词
