Multimodal image registration for preoperative planning and image-guided neurosurgical procedures.
Image registration is the process of transforming images acquired at different time points, or with different imaging modalities, into the same coordinate system. It is an essential part of any neurosurgical planning and navigation system because it facilitates combining images with important complementary, structural, and functional information to improve the information based on which a surge...
متن کاملMultimodal visualizations for pre-operative neurosurgical planning
In the living brain, vital structures include cortical areas as well as neuronal pathways connecting these. If pathologies, for example a tumor are present and derogate essential functionalities, neurosurgical treatment is needed. Neurosurgeries are tailored to the patient-specific anatomy and pathology: Within an individual preoperative planning phase the most adequate access path to a lesion ...
متن کاملMultimodal image registration of the scoliotic torso for surgical planning
BACKGROUND This paper presents a method that registers MRIs acquired in prone position, with surface topography (TP) and X-ray reconstructions acquired in standing position, in order to obtain a 3D representation of a human torso incorporating the external surface, bone structures, and soft tissues. METHODS TP and X-ray data are registered using landmarks. Bone structures are used to register...
متن کاملHierarchical segmentation-assisted multimodal registration for MR brain images
Information theory-based metric such as mutual information (MI) is widely used as similarity measurement for multimodal registration. Nevertheless, this metric may lead to matching ambiguity for non-rigid registration. Moreover, maximization of MI alone does not necessarily produce an optimal solution. In this paper, we propose a segmentation-assisted similarity metric based on point-wise mutua...
متن کاملMultimodal (MRI/PET) Fusion of Cerebral Images in Multiresolution Domain
As a result of the development of imaging techniques and information technology, it is possible to have several heterogeneous data. The fusion an anatomic imaging such as the magnetic resonance imagery (MRI) and functional imaging type such as the positron emission tomography (PET), made it possible to lead to a greater complementarities of data. In this work, we present a comparative study of ...
