Robustness of Mutual Information Based Intra-Operative Registration

We investigated the robustness of the registration of intra-operative 3D rotational angiography (3DRA) data with pre-operative anatomical data, such as CT and MR. The analysis has been done in the context of interventional treatment of vascular pathologies and endovascular treatment of the neoplastic tissue. We used Mutual Information as similarity measure, and the Powell algorithm as optimizer. The robustness was measured as function of translation in different directions and rotation around different axes, for 11 patients.
