Abstract
An imaging system for tracking brain deformation, a method for tracking brain deformation, a method of operating a device for tracking brain deformation are disclosed. A first 3D representation (112) of a cerebrovascular vessel structure of a region of interest of an object is provided (110), and (114) a second 3D representation (116) of the cerebrovascular vessel structure are used to determine brain deformation. At least a part of the first 3D representation is elastically three-dimensionally registered (118) with at least a part of the second 3D representation. A deformation field (122) of the cerebrovascular vessel structure is determined (120) based on the elastic registration. The determined vessel deformation is applied (124) to a brain structure representation to determine a deformation (126) of the cerebral structure.
