    摘要： A computing system may generate an initial segmentation mask by applying a neural network to a 3D image of a set of objects. The initial segmentation mask associates voxels of the 3D image with individual objects of the set of objects. Additionally, the computing system generates a refined segmentation mask. As part of generating the refined segmentation mask, the computing system performs, for each respective object, a front propagation process for the respective object. The front propagation process for the respective object uses input voxel data to relabel, in the refined segmentation mask, voxels of the 3D image as being associated with the respective object. A stopping condition of a path evaluated by the front propagation process for the respective object occurs when the front propagation process evaluates a voxel identified in the initial segmentation mask as being associated with a different one of the objects from the respective object.

    摘要： A humeral guide is provided that has a first portion or member configured to be positioned on a portion of a proximal humerus. The first portion or member can be configured to rest in a complementary manner on the portion of the proximal humerus. The humeral guide can be configured with apertures defining trajectories through bone, the pin trajectories being diverging in some case and in some cases being selected to enhanced support. A second portion or member and a third portion or member of the humeral guide are configured to be positioned on first and second lateral portions of the humerus distal to a location intended for resection, e.g., between an anatomical neck and a distal end of the humerus. The second and third portions or members or portions are configured to rest in a complementary manner on the first and second lateral portions of the humerus. The humeral guide can be configured to avoid soft tissue between a bone facing side and the humerus. The humeral guide can have a removeable jig portion.
