Claim 0:
1. An apparatus, comprising:
a computer processor configured for communication with an extraluminal imaging device and a display, wherein the computer processor is configured to:
drive the display to display an extraluminal roadmap image of a lumen of a body of a subject, the extraluminal roadmap image showing a pathway of the lumen, wherein the extraluminal roadmap image is obtained with a contrast agent within the lumen;
identify, in the extraluminal roadmap image, a plurality of first pixels comprising the pathway of the lumen;
acquire, using the extraluminal imaging device, a first extraluminal image, wherein the first extraluminal image is obtained without the contrast agent within the lumen;
select a master image comprising a plurality of second pixels, wherein the master image comprises the first extraluminal image or a blank image with a size corresponding to a size of the first extraluminal image;
determine a closest pixel of the plurality of second pixels to a pixel of the plurality of first pixels;
determine a distance between the closest pixel of the plurality of second pixels and the pixel of the plurality of first pixels;
acquire, using the extraluminal imaging device, a plurality of second extraluminal images of an endoluminal device moving along the lumen, wherein the plurality of second extraluminal images is obtained without the contrast agent within the lumen; and
for each respective extraluminal image in the plurality of second extraluminal images:
identify, in the respective extraluminal image, a pixel that includes the endoluminal device;
map the pixel that includes the endoluminal device to the closest pixel of the plurality of second pixels;
determine, for the respective extraluminal image, a location of the endoluminal device on the pathway of the lumen while the endoluminal device moves along the lumen, wherein the determined location is determined based on the mapping; and
drive the display to display, on the extraluminal roadmap image, an output indicative of the determined location while the endoluminal device moves along the lumen.
