Abstract
A system and a computer-implemented method for intra-operatively predicting an outcome of a planar cut performed with a planar surgical tool on a target bone of a subject, wherein the planar surgical tool comprises a planar cutting surface. Also, non-transitory computer readable medium including instructions which, when executed by a computer, cause the computer to carry out the steps of the method.
Claims15
A computer-implemented method for intra-operatively predicting an outcome of a planar cut performed with a planar surgical tool on a target bone of a subject, wherein said planar surgical tool comprises a planar cutting surface, said method comprising:
- receiving at least one 3D image previously acquired from at least one 3D imaging sensor;
- said 3D image being a 3D point cloud comprising at least one portion of the target bone and at least one portion of planar cutting surface of the surgical tool,
- segmenting the 3D image obtaining points of the 3D image belonging to the planar cutting surface of the surgical tool and points of the 3D image belonging to the target bone;
- obtaining the spatial orientation and position of an osteotomy plane by fitting a plane to the segmented points belonging to the planar cutting surface of the surgical tool;
- overlapping the osteotomy plane to the segmented points belonging to the target bone and selecting the points belonging to the portion of target bone intended to be removed with the surgical tool;
- and
- outputting the points belonging to the portion of target bone intended to be removed with the surgical tool (Pr).
A system for intra-operatively predicting an outcome of a planar cut performed with a planar surgical tool on a target bone of a subject, wherein the planar surgical tool comprises a planar cutting surface, said system comprising:
- at least one input adapted to receive at least one 3D image previously acquired from at least one 3D imaging sensor, said 3D image being a 3D point cloud comprising at least one portion of the target bone and at least one portion of the planar cutting surface of the surgical tool,
- at least one processor configured to:
- segment the 3D image obtaining points of the 3D image belonging to the planar cutting surface of the surgical tool and points of the 3D image belonging to the target bone;
- obtain the spatial orientation and position of an osteotomy plane by 3D fitting the segmented points belonging to the planar cutting surface of the surgical tool;
- and
- overlap the osteotomy plane to the segmented points belonging to the target bone and selecting the points belonging to the portion of target bone intended to be removed with the surgical tool;
- and
- at least one output adapted to provide the points belonging to the portion of target bone intended to be removed with the surgical tool.
