Abstract
Selective reflection of light by ureters and by tissue around the ureters is used to safely and efficiently image the ureters. In one aspect, a plurality of surgical site scenes is captured. Each of the plurality of surgical site scenes is captured from reflected light having a different light spectrum. The plurality of captured surgical site scenes is analyzed to identify ureter tissue in the captured surgical site scenes. A surgical site scene is displayed on a display device. The displayed surgical site scene has ureter tissue artificially highlighted.
Claims20
A method comprising:
- capturing a plurality of surgical site scenes, each of the plurality of surgical site scenes being captured from reflected light having a different light spectrum;
- and
- analyzing the plurality of captured surgical site scenes to identify ureter tissue in the captured surgical site scenes.
A surgical system comprising:
- an image capture system, the image capture system being configured to capture a plurality of surgical site scenes, each surgical site scene in the plurality of surgical site scenes being captured from reflected light of a different waveband of a plurality of wavebands, each waveband of the plurality of wavebands being reflected differently by ureter tissue and tissue around the ureter tissue;
- and
- a ureter analysis module coupled to the image capture system, the ureter analysis module being configured to identify ureter tissue in the captured surgical site scenes.
A surgical system comprising:
- means for capturing a plurality of surgical site scenes, each of the plurality of surgical site scenes being captured from reflected light having a different light spectrum, each light spectrum being reflected differently by ureter tissue and tissue around the ureter tissue;
- and
- means for analyzing the plurality of captured surgical site scenes to identify ureter tissue in the captured surgical site scenes.
