Abstract
An apparatus (IP) and a method to point-wisely reconstruct 3D image a 3D image volume of one or more 3D image volumina (Vp, Vc, Vv) to record changes of configuration of an embolus (E) introduced in an embolization procedure into a region of interest (ROI) of an object (OB)
Claims16
An image processing apparatus, comprising:
- an input unit for receiving from a first channel a stream of projection images of an object acquired along a first projection direction and from a second channel a stream of projection images of the object acquired along a second projection direction, the images in both channels acquired whilst a material volume of a material resident in the object undergoes a configuration change;
- an identifier configured to identify, based on i) a pair of an earlier first channel image and a later first channel image and on ii) a pair of an earlier second channel image and a later second channel image, image portions, one in the later first channel image and one in the later second channel image, said image portions indicative of the material volume's configuration change and indicative to a position where in the material volume said change occurred;
- a 3D image reconstructor configured to reconstruct, only upon the identifier successfully identifying said image portions, from the identified image portions a 3D image volume element, the so reconstructed 3D image volume element representative only of said identified image portions;
- and
- an output port configured to output the reconstructed 3D image volume element.

Method of image processing, comprising the steps of:
- receiving from a first channel a stream of projection images of an object acquired along a first projection direction and from a second channel a stream of projection images of the object acquired along a second projection direction, the images in both channels acquired whilst a volume of material is resident in the object and whilst said material volume is capable of undergoing a configuration change;
- identifying, based on i) a pair of an earlier first channel image and a later first channel image and on ii) a pair of an earlier second channel image and a later second channel image, image portions, one in the later first channel image and one in the later second channel image, said image portions indicative of the material volume's configuration change and indicative to a position where in the material volume said change occurred;
- only upon successfully identifying said image portions, reconstructing from the identified image portions a 3D image volume element, the so reconstructed 3D image volume element representative only of said identified image portions;
- and
- outputting the reconstructed 3D image volume element.
