3D-originated cardiac roadmapping

摘要

A 3D-originated cardiac roadmapping device and method include providing 3D+t image data of a vascular structure of an object; acquiring 2D image data of the object that includes the vascular structure, where the 2D image data includes at least one 2D image. The method further includes projecting the vascular structure, thereby generating mask images based on the 3D+t image data; and registering the at least one 2D image with one of the mask images. The registration includes finding the maximum of a similarity factor between the mask images and the at least one 2D image. The method further includes generating a combination of the at least one 2D image and a projection of the vascular structure based on the 3D+t image data according to the registration; and displaying the combination as a guiding vessel tree projection.

主权项

1. A device for 3D-originated cardiac roadmapping, comprising:
a processor configured to receive 3D+t image data of a vascular structure of an object; and to receive 2D image data of the object, the 2D image data comprising at least one 2D image; and a display; wherein the processor is further configured to
project the vascular structure, thereby generating a plurality of mask images based on the 3D+t image data;perform a registration of the at least one 2D image with one of the plurality of the mask images by finding a maximum of a similarity factor between the plurality of mask images and the at least one 2D image; andgenerate, according to the registration, a combination of the at least one 2D image and a projection of the vascular structure based on the 3D+t image data; wherein the display is configured to display the combination as a guiding vessel tree projection, wherein an element is located inside a vessel of the vascular structure, wherein the element is visible in the 2D image data, and wherein the display is further configured to display the combination as the guiding vessel tree projection having sub-branches, wherein sub-branches of the sub-branches that do not include the element are attenuated based on a distance from the element for greater fading as the distance increases.
