Figure Lengend Snippet: Bone Surface D istance Repeatability Analysis Pipeline. (A) To assess bone surface repeatability, two DESS MRI scans from a single participant are inputted into the trained tibia and femur segmentation models. (B) The trained models predict the tibia and femur masks. (C) The outer contours from the predicted masks are extracted and reconstructed into 3D models using Geomagic Studio 11 (3D Systems; Research Triangle Park, North Carolina). (D) The tibia and femur models from Scan 1 and Scan 2 are aligned using an iterative closest point technique . (E) Bone surface distances in the x-, y-, and z-directions are calculated between the two scans across all regions of interest . M ​= ​medial and L ​= ​lateral.

Article Snippet: Bone and Cartilage 3D Model Reconstruction Pipeline. (A) Each DESS MRI scan is inputted into the 4 trained segmentation models, and binary masks are outputted for each of the 4 tissues. (B) Visualization of the predicted bone and cartilage masks overlaid on the original DESS MRI scan. (C) Mask contours are extracted, converted into point clouds, and reconstructed into 3D surface mesh models using Geomagic Studio 11 (3D Systems; Research Triangle Park, North Carolina).
