This study introduces a novel markerless surface registration method for neurosurgery navigation. The approach efficiently aligns pre-operative and intra-operative patient faces, improving surgical accuracy and reducing setup time.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Aided Surgery

Background:

  • Accurate registration of pre-operative images to intra-operative patients is vital for successful neurosurgery navigation.
  • Current methods may involve tedious setup processes for surgeons.

Purpose of the Study:

  • To develop and evaluate an efficient and robust markerless surface registration method for neurosurgery navigation.
  • To compare the proposed method with existing registration techniques like Iterative Closest Point (ICP) and Coherent Point Drift (CPD).

Main Methods:

  • Reconstruction of the intra-operative face using structured light.
  • Segmentation of the pre-operative face from CT/MRI images.
  • Development of a Scale Invariant Feature Transform (SIFT)-based markerless surface registration algorithm for aligning faces.

Main Results:

  • The proposed SIFT-based registration method demonstrated competitive accuracy with an average symmetrical surface distance (ASD) of 2.30 ± 0.69 mm.
  • The method achieved a significantly faster running time (0.58 s) compared to ICP (343.46 s) and CPD (3847.56 s).
  • Validation was performed on 10 volunteers and one synthetic model.

Conclusions:

  • The developed system enables rapid intra-operative face reconstruction and efficient, accurate alignment with pre-operative images.
  • This approach meets the registration demands of neurosurgery navigation while simplifying the surgical workflow.
  • The method offers a promising solution for enhancing precision and reducing setup time in image-guided neurosurgery.
