Abstract
Deep Brain stimulation (DBS) surgery is microelectrode-guided surgery for the treatment of patients with movement disorders. DBS on deep brain structures requires effective postoperative procedures for analysis of surgical success. Thus, brain shift analysis is an important stage of DBS surgery where pre-operative and postoperative images are compared to measure the brain shift. Since information gained from two images acquired in the clinical track of events is usually complementary, properly integrating useful data obtained from the separate images is challenging. The integration process to bring the modalities involve spatial alignment, a procedure referred to as registration. Registration is typically followed by a fusion step required for the integrated display of the image data. This paper presents a novel approach that focuses on multimodality data fusion to analyze the pre-operative and postoperative CT and MR images. Our multimodal image registration model considers brain images based on a projection-based reference image. The registration is based on sharing mass in a predetermined direction: axial, sagittal, and coronal. Then, the region of interest is registered through modified mutual information based on the overlap rate and a weight assigned to it. Our approach is a combination of both coarse and fine registration techniques.
