The apparatus comprises a patient support unit, an acquisition unit, a data processing and control unit, and a display unit. The patient support unit is configured to bed a patient, free of motion, on the patient support. The acquisition unit is configured to acquire scout images of the patient including the object of interest in a respective position of the apparatus having position parameters. The data processing and control unit is configured to store the images and at least one respective position parameter including the iso-center position relative to the image; and to adjust the position of the apparatus roughly into a present position for CT scanning of the object of interest; and to select at least one iso-centering image from the stored images and, by geometrical calculation using, firstly, the at least one stored position parameter of the iso-centering image including the stored iso-center position and using, secondly, at least one position parameter of the present position of the apparatus including the present iso-center, adopting the appearance of the at least one iso-centering image, such that the appearance of the iso-centering image is according to the present position of the C-arm including the present iso-center.

    摘要: 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.
