Abstract
According to an exemplary embodiment of the present invention, a cardiac roadmapping technique is provided, that does not rely on the prerequisite of a phase-centric pairing of the angiogram and life images. Instead, both the pairing and accurate registration of the images are combined within a single operation, for example by using a multi-device map. This may provide for robust and precise cardiac roadmapping.
Claims15
Examination apparatus for cardiac roadmapping for examination of an object of interest, the examination apparatus comprising:
- a determination unit adapted for performing a cardiac roadmapping on the basis of at least one of:
- a global correlation determination of a first image sequence of the object of interest and a second image sequence of the object of interest, and
- a correlation determination of a first image of the object of interest and a second image of the object of interest on the basis of an identification of a first object and a second object in the first image and the second image.
A method for cardiac roadmapping for examination of an object of interest (107) with an examination apparatus (100), method comprising the steps of:
- performing a cardiac roadmapping on the basis of at least one of:
- a global correlation determination of a first image sequence of the object of interest and a second image sequence of the object of interest, and
- a correlation determination of a first image of the object of interest and a second image of the object of interest on the basis of an identification of a first object and a second object in the first image and the second image.
A computer-readable medium (402), in which a computer program for cardiac roadmapping for examination of an object of interest is stored which, when executed by a processor (401), causes the processor to carry out the steps of:
- performing a cardiac roadmapping on the basis of at least one of:
- a global correlation determination of a first image sequence of the object of interest and a second image sequence of the object of interest, and
- a correlation determination of a first image of the object of interest and a second image of the object of interest on the basis of an identification of a first object and a second object in the first image and the second image.
A program element for cardiac roadmapping for examination of an object of interest (107), which, when being executed by a processor (401), causes the processor to carry out the steps of:
- performing a cardiac roadmapping on the basis of at least one of:
- a global correlation determination of a first image sequence of the object of interest and a second image sequence of the object of interest, and
- a correlation determination of a first image of the object of interest and a second image of the object of interest on the basis of an identification of a first object and a second object in the first image and the second image.
An image processing device for cardiac roadmapping for examination of an object of interest (107), the image processing device comprising:
- performing a cardiac roadmapping on the basis of at least one of:
- a global correlation determination of a first image sequence of the object of interest and a second image sequence of the object of interest, and
- a correlation determination of a first image of the object of interest and a second image of the object of interest on the basis of an identification of a first object and a second object in the first image and the second image.
