Project Description

Objective

  • Work toward a real-time trackerless image-based registration that is constrained by a clinically relevant geometry.
  • Can support calibration / registration with tracked-systems

Approach, Plan

  • Evaluate and develop various image-similarity metrics in a geometrically constrained search space.
  • Rather than relying on an optimizer, the goal would be to find a fast similarity metric that enables a dense sampling of the objective function search space.

Progress

  • Initial good results with the LC2 metric constrained to a craniotomy site.
  • Given a pair of registered US-MRI images, the module calculates the similarity metric output perturbed between the two images.
