ARTIFICIAL-INTELLIGENCE-BASED DETECTION OF INVISIBLE ANATOMICAL STRUCTURES IN 2D X-RAY IMAGES

摘要

A system with a processing unit for processing X-ray images may be utilized for assisting in humerus surgery based on X-ray images. Firstly, at least two X-ray images are received having been generated with different imaging directions and showing a proximal portion of a humerus. Then, (i) the X-ray images are registered, (ii) an approximation of at least a part of the 2D outline of the humerus head in both images is determined, (iii) a 3D approximation of the humerus head based on the approximated 2D outlines and the registered images is determined, and (iv) 2D image coordinates of a total of at least three different points in the X-ray images are determined. Finally, an approximation of an anatomical neck is determined as a curve on the 3D approximation of the humerus head based on the at least three determined points.
