Ct-based Navigation

Image registration aligns reconstructed CT data with the patient’s actual anatomy. This correspondence lets the navigation system relate the displayed three-dimensional model to the operative region, rather than treating the images as an isolated reference. Accurate alignment is therefore central to localizing lesions, selecting trajectories, and interpreting instrument positions relative to nearby structures.

Three-dimensional reconstruction converts CT slices into a navigable model of the relevant anatomy, making spatial relationships easier to plan and interpret. Instrument tracking then links a surgical tool or target to that model, showing its position relative to planned anatomy. Together, these functions connect preoperative imaging with procedural guidance in complex regions.

Anatomically complex cranial regions contain lesions, trajectories, and critical structures whose spatial relationships must be understood during planning. Ct-based Navigation provides a three-dimensional representation and relates instruments or targets to that representation. This can help clinicians localize intended targets and avoid vulnerable tissue during neurosurgical procedures.

A basic workflow begins with preoperative CT imaging, followed by reconstruction into a three-dimensional model. The model is registered to the patient’s anatomy, after which instruments or targets can be tracked relative to the displayed images. This sequence supports procedural planning and provides anatomical guidance while the intervention is performed.

In neuroscience, the method can support localization of lesions, planning of instrument trajectories, and identification of critical structures during neurosurgical procedures. By displaying these relationships in a shared image-guided framework, it helps clinicians connect preoperative anatomical information with the operative task. The resulting guidance can support precise, minimally invasive intervention in regions where vulnerable tissue must be considered.

The system provides a spatial reference that relates tracked instruments or targets to reconstructed CT anatomy. Clinicians can use that relationship to assess where a tool or target lies relative to lesions, planned trajectories, and critical structures. In practice, this supports real-time anatomical guidance, helps clinicians avoid vulnerable tissue, and maintains continuity between imaging-based plans and the procedure.
