Tracking brain deformation during neurosurgery
First Claim
1. A device for tracking brain deformation, the device comprising:
- a processor; and
an image acquisition device that acquires and provides to the processor a first 3D representation of a cerebrovascular vessel structure of a region of interest of an object and a second 3D representation, which is based on X-ray image data, of the cerebrovascular vessel structure,wherein the processor;
elastically three-dimensionally registers the first 3D representation with the second 3D representation,determines, after executing the elastic registration, a deformation field indicating vessel deformation of the cerebrovascular vessel structure based on the elastic registration of the first 3D representation with the second 3D representation, andapplies the determined vessel deformation to a brain structure representation to determine a deformation of the brain structure.

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.
