Below is my approach at using Fiducial Registration to create a Warping transform and deform the skin of the model to match the motion of the osteotomies.
- I appended the model of the Skull to both the Original Orbital Bandeau and the Advanced/Modified Bandeau, creating a “Source” and “Target” model. My goal here is to ensure that the transformation requires a deformation of the model, rather than simply resulting in a translation.
- I added “From” and “To” Fiducials to both the “Source” and “Target” models, with some of these coinciding on the Skull
- I generated a “Warping” transform using the Fiducial Registration Module and applied it to a model of the patient’s soft tissue.
This seemed to work but I believe it is influenced by areas with more fiducials. The right orbit of the skull model has like 2-3 more fiducials and there seems to be more deformation on that side. A simple overlay of the two models shows this.
So, my questions are:
- Is this a valid approach?
- Is this an efficient approach? or, is there a more generalized solution?
- Is there a way of using the surface vertices of the models as fiducials?
Thank you!
