Co-use of endoluminal data and extraluminal imaging
First Claim
1. A method for use with an endoluminal data-acquisition device configured to be moved through a lumen of a subject'"'"'s body, the endoluminal data-acquisition device having a radiopaque marker coupled thereto, comprising:
- while the endoluminal data-acquisition device is being moved through the lumen;
acquiring a plurality of endoluminal data points of the lumen using the endoluminal data-acquisition device;
continuously injecting contrast agent into the lumen; and
acquiring a plurality of angiographic images of the lumen, during the continuous injection of the contrast agent into the lumen;
determining that endoluminal data points correspond to respective locations within the lumen, by determining locations of the radiopaque marker within the angiographic images of the lumen, by performing image processing on the angiographic images, the locations of the radiopaque marker within the angiographic images of the lumen corresponding to respective endoluminal data points; and
generating an output in response thereto.

Abstract
Apparatus and methods are described for use with an endoluminal data-acquisition device configured to be moved through a lumen, the device having a radiopaque marker coupled thereto. While the device is being moved through the lumen (a) endoluminal data points of the lumen are acquired using the device, (b) contrast agent is continuously injected into the lumen, and (c) angiographic images of the device are acquired. It is determined that endoluminal data points correspond to respective locations within the lumen, by determining locations of the radiopaque marker within the angiographic images of the lumen, by performing image processing on the angiographic images, the locations of the radiopaque marker within the angiographic images of the lumen corresponding to respective endoluminal data points. Other applications are also described.

7. Apparatus for use with:
-
an endoluminal data-acquisition device configured to acquire a plurality of endoluminal data points of a lumen of a body of a subject at respective locations inside the lumen, while the endoluminal data-acquisition device is being moved through the lumen, the endoluminal data-acquisition device having a radiopaque marker coupled thereto, and an angiographic imaging device configured to acquire a plurality of angiographic images of the lumen, during the movement of the endoluminal data-acquisition device through the lumen, the angiographic images being acquired while a contrast agent is continuously injected into the lumen, the apparatus comprising; a display configured to display images of the lumen; and at least one processor configured to; determine that endoluminal data points correspond to respective locations within the lumen, by determining locations of the radiopaque marker within the angiographic images of the lumen that were acquired while the contrast agent was continuously injected into the lumen, by performing image processing on the angiographic images, the locations of the radiopaque marker within the angiographic images of the lumen corresponding to respective endoluminal data points, and drive the display to display an output, in response to determining that the endoluminal data points correspond to respective locations within the lumen. - View Dependent Claims (8)
