Claim 12:
13. A non-transitory computer-readable medium having computer executable instructions stored thereon, which, when executed by a processor of a computing device, cause the computing device to perform a method of determining information regarding cross-sectional areas of a passageway of anatomy for fluid flow, the method comprising:
obtaining a three-dimensional (“3-D”) model of the passageway;
placing at least a portion of a representation of a prosthetic device in the 3-D model of the passageway at a position;
determining a starting plane that intersects at least a point of a surface of the representation of the prosthetic device at the position, at least a point in a volume defined by the passageway, and at least a point on a surface of the passageway;
creating a plurality of section planes based on rotating the starting plane one or more times about one or more axes;
calculating a plurality of cross-sectional areas corresponding to the plurality of section planes, wherein each cross-sectional area is calculated as a difference between a first cross sectional area of an intersection of the volume and a corresponding section plane and a second cross-sectional area of an intersection of the at least the portion of the representation of the prosthetic device at the position and the corresponding section plane;
determining one of a maximum or minimum cross-sectional area of the plurality of cross sectional areas;
comparing the one of the maximum or the minimum cross-sectional area to a threshold; and
selectively changing a prosthetic device corresponding to the representation of the prosthetic device based on the comparison.
