METHODS, APPARATUSES, ASSEMBLIES, CIRCUITS AND SYSTEMS FOR ASSESSING, ESTIMATING AND/OR DETERMINING RELATIVE POSITIONS, ALIGNMENTS, ORIENTATIONS AND ANGLES OF ROTATION OF A PORTION OF A BONE AND BETWEEN TWO OR MORE PORTIONS OF A BONE OR BONES

摘要

The present invention includes methods, apparatuses, assemblies, circuits and systems for assessing, estimating and/or determining relative distances/positions, alignment, orientation and angles of rotation of a portion of a bone and between two or more portions of a bone, e.g. a fractured bone. According to some embodiments of the present invention, there may be provided a reference object (e.g. a reference grid), which reference object may include an array of reference markings visible in a radiographic image. The reference object may be used in conjunction with one or more radiographic imaging devices and image processing circuitry to facilitate determination of a 3D position and orientation of points within images acquired by the imaging devices from different angles and spatial relationships between these points.
