| Popis | A nonlinear registration method able to handle multimodal image data is designed and used for deformation based morphometry in 3D structural MRI brain scans. The registration process is driven by local forces derived from multimodal point similarity measures which are estimated with the use of joint intensity histogram and tissue probability maps. A spatial deformation model imitating principles of continuum mechanics is used. Results of application of the method in automated spatial detection of anatomical abnormalities in first episode schizophrenia are presented. |
