As used herein, "osteotomy procedure" or "surgical osteotomy" refers to a surgical operation in which one or more bones are cut to shorten or lengthen them or to change their alignment. The procedure can include removing one or more portions of bone and/or adding one or more portions of bone or bone substitutes. (Search "osteotomy" on Wikipedia.com Feb. 3, 22, 2021.

"Wedge osteotomy" refers to an osteotomy procedure in which one or more wedges are used as part of the procedure. Generally, wedge osteotomies can be of one of two types, open wedge and closing wedge. The type of osteotomy refers to how the procedure changes the relation between two parts of a bone involved in the osteotomy. In an open wedge osteotomy a wedge of bone or graft or other material is inserted in between two parts of a bone. Consequently, a wedge shape is "opened" in the bone. In a close wedge osteotomy or closing wedge osteotomy a wedge of bone is removed from a bone. Consequently, a wedge shape formed in the bone is "closed." |

As used herein, "artificial intelligence" refers to intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals, which involves consciousness and emotionality. The distinction between artificial intelligence and natural intelligence categories is often revealed by the acronym chosen. 'Strong' AI is usually labelled as artificial general intelligence (AGI) while attempts to emulate 'natural' intelligence have been called artificial biological intelligence (ABI). Leading AI textbooks define the field as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of achieving its goals. The term "artificial intelligence" can also be used to describe machines that mimic "cognitive" functions that humans associate with the human mind, such as "learning" and "problem solving".

Certain computer vision techniques can be used or adapted for image segmentation. For example, the techniques and or algorithms for segmentation may include, but are not limited to: Atlas-Based Segmentation: For many applications, a clinical expert can manually label several images; segmenting unseen images is a matter of extrapolating from these manually labeled training images. Methods of this style are typically referred to as atlas-based segmentation methods. Parametric atlas methods typically combine these training images into a single atlas image, while nonparametric atlas methods typically use all of the training images separately. Atlas-based methods usually require the use of image registration in order to align the atlas image or images to a new, unseen image. |
