Warping a Neuro-Anatomy Atlas on 3D MRI Data with Radial Basis Functions
نویسندگان
چکیده
Navigation for neurosurgical procedures must be highly accurate. Often small structures are hardly seen on pre-operative scans. Fitting a 3D electronic neuroanatomical atlas on the data assists with the localization of small structures and dim outlines. During surgery also brainshifts occurs. With intra-operative MRI the preoperative MRI can be warped to the real 3D situation. The paper describes a general 3D landmark-based warping method, based on radial basis functions (thin plate splines) for data of any number of dimensions, including all code in Mathematica. Keywords— Brain atlas, image warping, radial basis functions, neurosurgery, computer vision

A method for atlas-based volumetric registration with surface constraints for Optical Bioluminescence Tomography in small animal imaging
Atlases are normalized representations of anatomy that can provide a standard coordinate system for in vivo imaging studies. For Optical Bioluminescence Tomography (OBT) in small animals, the animal’s surface topography can be reconstructed from structured light measurements, but internal anatomy is unavailable unless additional CT or MR images are acquired. We present a novel method for estima...
متن کاملA Multi-Modality Computer-Aided Framework Towards Postmortem Identification
A multi-modality framework for forensic soft-facial reconstruction based on computed tomography CT and magnetic resonance imaging MRI is presented. CT is used to acquire a virtual representation of a skull find and MRI templates provide the desired soft tissue information to produce a facial likeness of a deceased individual. Two main strategies are described. The first is based on a regularize...
متن کاملDevelopment of an Anaglyph Anatomical Atlas of Rabbit as a New Generation of Printable 3D Anatomical Atlases
Introduction: To improve anatomical atlases, we tried to create a printable 3D atlas of rabbit's anatomy based on the Anaglyph. Methods: In this study, twenty white rabbits euthanized and dissected. All 3D images were reconstructed by means of "stereo photo maker (SPM®)" software. Results: By this atlas, users can easily understand nomenclature, the topography and, certainly, the transpo...
متن کاملA deformable digital brain atlas system according to Talairach and Tournoux
Brain atlases are valuable tools which assist neurosurgeons during the planning of an intervention. Since a printed atlas book has several disadvantages-among them the difficulty to map the information onto a patient's individual anatomy-we have developed a digital version of the well-established stereotaxic brain atlas of Talairach and Tournoux. Our atlas system is mainly dedicated to assist n...
متن کاملImage Warping by Radial Basis Functions: Application to Facial Expressions
The human face is an elastic object. A natural paradigm for representing facial expressions is to form a complete 3D model of facial muscles and tissues. However, determining the actual parameter values for synthesizing and animating facial expressions is tedious; evaluating these parameters for facial expression analysis out of grey-level images is ahead of the state of the art in computer vis...
