Abstract

The present invention relates to the determination of brain deformation. The invention relates in particular to a device for tracking THE brain deformation, an imaging system for tracking the brain deformation, a method for tracking the brain deformation, a method of operating a device for tracking the brain deformation, as well as relates to a computer program element and a computer readable medium. For providing enhanced information about the brain deformation, 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. Then, 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. For example, planning data (130) for an intervention of the cerebral structure is provided (132) and the determined deformation of the cerebral structure is applied (134) to the planning data to generate deformation adjusted planning data (136).

Description

technical field [0001] The present invention relates to the determination of brain deformation. The invention relates in particular to a device for tracking brain deformations, an imaging system for tracking brain deformations, a method for tracking brain deformations, a method of operating a device for tracking brain deformations, And it relates to a computer program element and a computer readable medium. Background technique [0002] For neurointerventional therapy, image information about the region of interest is provided to the user. For example, US5954648 discloses showing the surgeon during surgery images that have been collected earlier. However, during neurosurgery, eg during neurosurgery or neurointerventional procedures, for example, leakage of cerebrospinal fluid can lead to localized deformation of the brain during the procedure. Consequently, image data acquired prior to treatment may be at least partially mismatched with the current brain structure. Cont...
