Airway bypass site selection and treatment planning
View Patent ↗This invention relates to systems and methods for site selection and placement of extra-anatomic passages altering gaseous flow in a diseased lung.
1. A method of assessing a plurality of treatment sites in airways of a lung of a patient, the method comprising:
identifying the plurality of sites within the airways of the lung;
determining at least one anatomic characteristic of each site;
assessing a diseased region to determine a degree of disease of the diseased region;
automatically calculating on a computer a score for each site based on: the degree of disease of the diseased region in the lung, at least one anatomic characteristic of each site and a proximity of the site to the diseased region; and
displaying each score in association with each site in graphical form.
2. The method of claim 1 , where identifying the plurality of sites comprises selecting at least one site per each segmental airway of the bronchi.
3. The method of claim 1 , further comprises displaying information regarding at least one anatomic characteristic of the site when displaying the score of the site.
4. The method of claim 1 , where determining at least one anatomic characteristic of each site comprises identifying a location of the blood vessels within a distance from the site.
5. The method of claim 1 , where calculating the score for each site comprises adjusting the score proportionally to the degree of the diseased region.
6. The method of claim 5 , where calculating the score for each site further comprises increasing the score as the proximity of the site to one of the diseased regions decreases.
7. The method of claim 1 , where determining at least one anatomic characteristic of each site comprises determining a size of airway diameter of each site.
