Abstract: A method and apparatus for displaying information concerning a tubular structure is disclosed. The method includes determining a centerline of the tubular structure and a plurality of center points along that centerline, determining a plurality of cross-sections at the respective center points that are perpendicular to the centerline, and identifying first values associated with each of the cross-sections and indicative of a first characteristic of the tubular structure. The method additionally includes generating a modified image of the tubular structure by determining a plurality of image lines corresponding to the respective cross-sections, and displaying a curve that represents the first characteristic alongside the modified image. The curve is formed by displaying, along a scale, a plurality of second values that are functionally related to the respective first values, each second value being positioned alongside the modified image along a respective one of the image lines.

Abstract: A method and an apparatus for displaying a structure of a vessel are disclosed. In one embodiment, the method includes identifying a centerline of the vessel within a portion of the vessel that includes the structure, identifying a contour of the vessel within a cross-sectional plane that is normal to a selected point along the centerline, measuring lengths of a plurality of segments that pass across the contour through the selected point, selecting one of the plurality of segments, and displaying an imaging plane defined by the selected one segment and an axis that is tangent to the centerline at the point. In another embodiment, the method includes determining a centerline of a tubular structure, selecting a section of the centerline, determining a plane that minimizes the distance to the selected section, and displaying the plane.
