Techniques for determining spatial orientation of input images for use in orthopaedic surgery

摘要

Problem to be solved: to provide a technique for determining the spatial orientation of an input image for generating a three-dimensional model.This technique acquires a two-dimensional image of an anatomical object (e.g., a human joint bone) and determines a candidate value which indicates the translation and rotation of an anatomical object in a two-dimensional image, and as a function of the acquired two-dimensional image and candidate value, the third order of the anatomical object candidate Includes a device having circuitry for generating the original model.The circuit determines the score indicating the accuracy of the candidate three-dimensional model, judges whether the score satisfies the threshold, and in response to the decision that the score satisfies the threshold value, it generates data indicating that the candidate three-dimensional model is an accurate representation of the anatomical object.Diagram
