Project Description

Objective

• Work toward a real-time trackerless image-based registration that is constrained by a clinically relevant geometry. (With special emphasis on intra-operative neuroimaging)
• 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.
