Quantification of a characteristic of a lumen of a tubular structure |
摘要 |
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 (216) 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. |

1. A method, comprising:
generating, based on a voxel distance map, a signal indicative of a quantification of a characteristic of a lumen of a tubular structure of interest over a pre-determined volume of the tubular structure of interest represented in volumetric imaging data; receiving a selected start point and end point of the tubular structure of interest; determining a state metric from the quantification that indicates a percentage of occlusion of the tubular structure of interest between the selected start point and end point; and wherein the percentage of occlusion is based on a selected diameter and a minimum diameter between the start and end points, wherein the selected diameter includes at least one of: an average of all diameters between the selected start point and end point, or an average of all diameters over a predetermined range along a path of the lumen. |
