Claim 11:
12. An apparatus for sizing a stent for placement in an artery, the apparatus comprising:
one or more processors, the one or more processors configured to:
receive, from an intravascular imaging probe, intravascular data including one or more image frames;
generate, based on the intravascular data, a representation of the artery, the representation composed of at least one of the one or more image frames;
provide for output the representation of the artery;
divide the representation of the artery into a plurality of segments, each segment defined as a space between branches of the artery the representation of the artery being divided into N+1 inter-branch segments, where N is a number of branches of the representation of the artery;
select a first segment from the plurality of segments and defining a maximum diameter of the first segment;
determine, based upon the defined maximum diameter of the first segment, a maximum diameter of a segment adjacent to the first segment;
determine an actual diameter of the adjacent segment;
select the larger of the determined maximum diameter or the actual diameter as the selected maximum diameter of the adjacent segment;
use the selected maximum diameter to find a maximum diameter of another segment;
iteratively proceed until a maximum diameter of each segment in the plurality of segments is determined;
automatically determine, based on the determined maximum diameters, one or more landing zones for most effective stent placement to reduce the complexities of stent planning;
provide for output results of examining the plurality of segments to allow a user to select the stent for intravascular placement in a lumen of the artery in response to a detected maximum lumen diameter of an end proximal segment and a detected maximum lumen diameter of an end distal end segment; and
in response to receiving a selection of the stent, provide for output a representation of the selected stent on the previously provided representation of the artery.
