Nonrigid Registration of Medical Images Based on Anatomical Point Landmarks and Approximating Thin-Plate Splines
نویسندگان
چکیده
Previous work on nonrigid registration of medical images based on thin plate splines has concentrated on using interpolation schemes Such schemes force the corresponding land marks to exactly match each other and thus assume that the landmark positions are known exactly However in real applications the localization of landmarks is always prone to error Therefore to cope with these errors we have investigated the application of an approximation scheme which is based on regularization theory In addition to this study we report on investigations into semi automatic extraction of anatomical point landmarks of the human brain

Landmark-Based Elastic Matching of 3D Medical Images
We describe an approach for 3D image registration based on a set of corresponding anatomical point landmarks and approximating thin-plate splines. This approach is an extension of the original interpolating thin-plate spline approach and has been introduced in [7] to cope with landmark localization errors. The extension is important for practical applications since landmark extraction is always...
متن کاملIncorporation of Landmark Error Ellipsoids for Image Registration Based on Approximating Thin-Plate Splines
Nonrigid registration of 3D tomographic images of di erent modalities (e.g., CT and MR images) is a key issue for neurosurgery and radiotherapy planning. Here, we consider image registration based on a set of corresponding anatomical point landmarks and approximating thin-plate splines. With this approach it is possible to take into account landmark localization errors and thus to control the i...

متن کاملRegistration of Magnetic Resonance Images of the Prostate Obtained with an Endorectal Coil to Histological Sections
Introduction Validation of findings from in vivo imaging (e.g. MRI) of the prostate requires precise correlation of histopathological information on a voxel-by-voxel basis, with sub-millimeter accuracy in the absence of identifiable anatomic landmarks. A method is developed to register histopathology sections and in vivo MR images of the prostate obtained with a combination of a phased-array an...
متن کاملNonrigid Medical Image Registration by Finite-Element Deformable Sheet-Curve Models
Image-based change quantitation has been recognized as a promising tool for accurate assessment of tumor's early response to chemoprevention in cancer research. For example, various changes on breast density and vascularity in glandular tissue are the indicators of early response to treatment. Accurate extraction of glandular tissue from pre- and postcontrast magnetic resonance (MR) images requ...
