Abstract
A method comprises providing a current state image and at least one reference image, taken from a similar angle range. The image and the at least one reference image are superimposed and a visual representation visualizing the relation between the image and the reference image is provided in order to track displacements of the bone during subsequent operation steps. A system is provided which can use the image data to track displacements and determine deviation from a current state of the elements in question to a target state.
Claims17
A method for displacement tracking during positioning and fixing of an implant in a bone, in particular in a hip bone, the method comprising:
- superimposing an image of the bone with at least one reference image, wherein the image of the bone is taken from a first angle and the at least one reference image is taken from a second angle, wherein the difference between the first angle and the second angle is no more than 5°, and
- visualizing a relationship between the image of the bone and the at least one reference image for tracking a displacement of the bone relative to an implant.
(canceled)
A system for displacement tracking during positioning and fixing of an implant in a bone, in particular in a hip bone, comprising:
- an imaging unit, and
- a processing unit,
- wherein the imaging unit is configured for providing an image of the bone and at least one reference image,
- wherein the processing unit is configured for superimposing the image of the bone with the at least one reference image, wherein the image of the bone is taken from a first angle and the at least one reference image is taken from a second angle, wherein the difference between the first angle and the second angle is no more than 5°, and
- wherein the processing unit is further configured for visualizing a relationship between the image of the bone and the at least one reference image for tracking a displacement of the bone relative to an implant.
