AI Technical Summary
Existing surgical navigation systems face challenges in tracking patient anatomy with sufficient degrees of freedom, particularly in non-rigid anatomical regions like the cervical spine, often resulting in bulky, expensive, and unreliable reference markers that can obstruct surgical sites and cause inaccuracies due to line of sight issues.
A distributed reference system with multiple reference markers attached to separate bodies of rigid tissue, connected by flexible tissue, allowing for tracking with a higher number of degrees of freedom using a processor to maintain registration with prior images, and incorporating deformation models to account for anatomical movements.
The system provides accurate tracking of non-rigid anatomy with reduced bulk and cost, minimizing exposure to x-rays while maintaining registration and improving surgical navigation accuracy.
