A method includes generating, based on a distance map, a signal indicative of a quantification of a characteristic of a lumen of a tubular structure of interest over a pre-determined extent of the tubular structure of interest represented in volumetric imaging data. A system includes a quantifying component () that generates, based on a distance map, a signal indicative of a quantification of characteristic of a lumen of a tubular structure of interest over a pre-determined extent of the tubular structure of interest represented in volumetric imaging data. A method includes identifying voxels of 3D segmented imaging data that represent tubular structure of interest, determining distances between the identified voxels and nearest voxels corresponding to other structure in a plurality of 2D slices of the segment imaging data, representing the voxels with intensity values that are proportional to the distances, and generating a signal indicative of a 3D distance map based on the intensity values.

Quantification of a characteristic of a lumen of a tubular structure

A three dimensional display system comprises a display () presenting a plurality of views of a scene where each view corresponds to a viewing direction for the scene. A rendering unit () generates an image for each of the views. The rendering unit () is capable of generating differentiated images for neighboring views containing differentiated image data providing a three dimensional depth effect when neighboring views are viewed by different eyes of a viewer. A user processor () generates a user presence estimate in response to an attempted detection of a user in a viewing area for the display system. A 3D mode controller () modifies the three dimensional effect in response to the user presence estimate. For example, the display system may provide a two dimensional image when no user is present and a three dimensional image when a user is present. This may reduce discomfort experienced by viewers in suboptimal positions.
