Objective

We are developing methods to perform interactive registration in 3D Slicer. The final goal is to provide user an interface to interact with the registration program during the matching progress, in case the result from automatic registration is not satisfactory.

Approach, Plan

Our approach for developing interactive registration module is to first construct the loadable extension to perform intensity-based registration, display the intermediate results, and allow user to pause the progress if the intermediate results are visually unsatisfactory. User inputs such as translation and rotation by dragging the mouse will be fed into the registration, and be used to correct the current transformation. Registration will continue to run starting from the corrected transform.

Progress

At the end of this week, we have a better understanding of the problems we are facing. We accomplished to have the first step of the steered registration which is the translation (illustrated above: "Interaction: Translate").
