Abstract
A method includes, using anatomical data, calculating multiple cross-sectional shapes of a lumen of an organ in a body of a patient at multiple respective positions on a medial axis of the lumen. One or more of the positions on the medial axis are identified, at which a given expandable frame of a catheter would fit the cross-sectional shapes. The one or more identified positions are presented to a user.
