Medical systems and methods

1. A method of treating an aneurysm, the method comprising:

exposing an aneurysm at a surgical site;

injecting a fluorescent dye into a blood vessel that includes the aneurysm;

capturing a first set of images of the surgical site with a camera;

analyzing the first set of images captured by the camera in a signal processing and analysis unit;

applying a clip to the aneurysm to clamp off the aneurysm;

after applying the clip to the aneurysm, capturing a second set of images of the surgical site with the camera;

analyzing the second set of images captured by the camera in a signal processing and analysis unit; and

comparing the first set of images with the second set of images to determine the effectiveness of the clip to clamp of the aneurysm.

2. The method of claim 1 , comprising:

analyzing the first set of images captured by the camera to determine a maximum fluorescent light intensity at multiple points on each of the recorded images; and

displaying an image that represents the maximum fluorescent light intensity at each of the multiple points.

3. The method of claim 2 , further comprising simultaneously displaying the first and second images.

4. The method of claim 3 , wherein the first and second images are displayed in a side-by-side fashion.

5. The method of claim 1 , comprising:

analyzing the first set of images captured by the camera to determine a time at which a predetermined fluorescent light intensity was reached for each of multiple points on each of the recorded images; and

displaying an image that represents a relative amount of time for each point to reach the predetermined fluorescent light intensity.

6. The method of claim 5 , further comprising simultaneously displaying the first and second images.

7. The method of claim 6 , wherein the first and second images are displayed in a side-by-side fashion.

8. The method of claim 1 , comprising:

analyzing the first set of images captured by the camera to determine a fluorescent light intensity at each of multiple points on each of the recorded images; and

displaying an image that represents the fluorescent light intensity for each of the multiple points over a period of time.

9. The method of claim 8 , further comprising simultaneously displaying the first and second images.

10. The method of claim 9 , wherein the first and second images are displayed in a side-by-side fashion.

11. The method of claim 1 , further comprising simultaneously displaying the first and second images.

12. The method of claim 11 , wherein the first and second images are displayed in a side-by-side fashion.

13. A method, comprising:

exposing an aneurysm at a surgical site;

injecting a marker in a blood vessel that includes the aneurysm;

capturing a first set of images of the surgical site;

using a signal processing and analysis unit to analyze the first set of images;

reducing blood flow to the blood vessel;

after reducing blood flow to the blood vessel, capturing a second set of images of the surgical site;

using the signal processing and analysis unit to analyze the second set of images; and

comparing the first set of images with the second set of images to determine the effectiveness of the reduction of blood flow to the blood vessel.

14. The method of claim 13 , wherein reducing blood flow to the blood vessel comprises clamping off the aneurysm.

15. The method of claim 14 , wherein clamping off the aneurysm comprises applying a clip to the aneurysm.

16. The method of claim 13 , comprising using a camera to capture the first set of images.

17. The method of claim 16 , comprising using the camera to capture the second set of images.

18. The method of claim 13 , further comprising treating the aneurysm based on the comparison of the first and second sets of images.
