Abstract

A system and method for vascular roadmapping include an X-ray imaging device for generating a fluoroscopy image, a data base in which a plurality of contrast-enhanced images is stored, a user interface element and a processor. Each of the contrast-enhanced images is stored together with the imaging parameters based on which the image is generated. The user interface element may be configured for selecting any intended imaging parameters, such as by manually adjusting the imaging device in any position and orientation. The processor may be configured for identifying a stored contrast-enhanced image out of the plurality of contrast-enhanced images, which is generated with specific imaging parameters, where the deviation of the specific imaging parameters from the intended imaging parameters is as small as possible, thus the processor may be configured for identifying the nearest available roadmap.

Dependent claims

A system for vascular roadmapping comprising:

an imaging device having an x-ray source and an x-ray detector, for generating a fluoroscopy image;
a data base including contrast-enhanced images, wherein the contrast-enhanced images are generated with different imaging parameters;
a user interface configured to select intended imaging parameters;
and
a processor configured:
to determine current imaging parameters of the imaging device,
to determine a contrast-enhanced image out of the contrast-enhanced images generated with respective imaging parameters, wherein the contrast-enhanced image has imaging parameters closest to the intended imaging parameters,
to select the contrast-enhanced image to obtain a selected contrast-enhanced image,
to adjust the current imaging parameters of the imaging device to the imaging parameters of the selected contrast-enhanced image, and
to determine that a state of the imaging device is a ready-for-use-state based on a completion of an adjustment of the current imaging parameters of the imaging device from the current imaging parameters to the imaging parameters of the selected contrast-enhanced image,
wherein the imaging parameters of the selected contrast-enhanced image comprises a position of the x-ray source and the x-ray detector, an orientation of the x-ray source and the x-ray detector, settings of the x-ray source, and settings of the x-ray detector, and
wherein the user interface is further configured to indicate the ready-for-use-state or the not-ready-for-use-state of the imaging device.
