Abstract
Methods of orthopedic fixation and imagery analysis are provided. Images of first and second bone segments attached to a fixation apparatus are captured. Fixator elements identified in the images can be used to obtain imaging scene parameters. Bone elements identified in the images can be used with the imaging scene parameters to reconstruct a three dimensional representation of positions and/or orientations of the first and second bone segments with respect to the fixation apparatus.
Claims20
A computer-implemented method of orthopedic fixation imagery analysis, the computer-implemented method comprising:
- acquiring, by one or more computing devices, first and second two dimensional images of a fixation apparatus and first and second bone segments attached thereto, wherein the first two dimensional image is captured from a first orientation and the second two dimensional image is captured from a second orientation that is different from the first orientation;
- obtaining, by the one or more computing devices, imaging scene parameters based in part on respective locations of a plurality of fixator elements of the fixation apparatus in the first and the second two dimensional images, wherein the obtaining of the imaging scene parameters is based at least in part on a conic that represents one or more geometries of one or more of the plurality of fixator elements;
- and
- reconstructing, by the one or more computing devices, a three dimensional representation of the first and the second bone segments with respect to the fixation apparatus based at least in part upon the conic, which is based in part upon the respective locations of the one or more of the plurality of fixator elements, that the imaging scene parameters are based in part upon.
One or more non-transitory computer-readable storage media having stored thereon instructions that, upon execution by one or more computing devices, cause the one or more computing devices to perform operations comprising:
- acquiring first and second two dimensional images of a fixation apparatus and first and second bone segments attached thereto, wherein the first two dimensional image is captured from a first orientation and the second two dimensional image is captured from a second orientation that is different from the first orientation;
- obtaining imaging scene parameters based in part on respective locations of a plurality of fixator elements of the fixation apparatus in the first and the second two dimensional images, wherein the obtaining of the imaging scene parameters is based at least in part on a conic that represents one or more geometries of one or more of the plurality of fixator elements;
- and
- reconstructing a three dimensional representation of the first and the second bone segments with respect to the fixation apparatus based at least in part upon the conic, which is based in part upon the respective locations of the one or more of the plurality of fixator elements, that the imaging scene parameters are based in part upon.
