Abstract:

Placement of N bars around the head of subject during an MR or a CT imaging session provides physicians, neurosurgeons with an analytical ability for preoperational target position determination in surgery, planning, Since axial slices yielded by a system mentioned above has 9 N bar spots, where the actual length between them is known, determination of the position of a point can be calculated by N bar points respect to any pre-selected origin. Even though, X-Ray CT and MRI are both complex, developed imaging modalities, none of them can be defined as perfect because of their limitations, Namely, when MR imaging is fine for soft-tissue filming, which turns it to be a strong candidate for neurosurgeries, where detailed imaging is important, CT is not as good as MRI, On the other hand, MRI is limited due to mostly, chemical shift, field non-uniformity for preoperational target determination, hence CT imaging becomes more appropriate for such a purpose, Our goal is to integrate brain atlases and CT images to overcome the drawbacks mentioned above by developing a tool providing the neurosurgeon with a preoperational target determination method by the atlas and CT image registration capability of the tool, Keywords - Brain Atlas, Anterior commisure, Posterior Commisure,Ventralis Intermediutus, CT
