Abstract
The present disclosure relates to systems and methods for visualizing a guidewire in a roadmap image. In accordance with certain embodiments, a method includes generating a background mask as a function of at least one background image, wherein the at least one background image includes a blood vessel of interest, generating a contrast mask as a function of at least one contrast image, wherein the at least one contrast image includes a contrast within the blood vessel of interest, receiving a guidewire image, wherein the guidewire image includes a guidewire within the blood vessel of interest, generating a roadmap image as a function of the background mask, contrast mask, and guidewire image, wherein the roadmap image includes the blood vessel of interest, and the guidewire, and outputting the roadmap image to a display.
