Embodiment Construction
[0227] The present invention is described in conjunction with specific embodiment:
[0228] A method for distinguishing between benign and malignant pulmonary nodules based on multidimensional information, comprising the following steps: figure 1 as shown,
[0229] Step 1. Two-dimensional representation of three-dimensional nodules;
[0230] Step 2, building a feature model;
[0231] Step 3, building a fuzzy classifier;
[0232] Step 4. Evaluate classification performance.
[0233] Step 1. Two-dimensional representation of three-dimensional nodules
[0234] The invention adopts the helical scanning technology to generate viewpoints distributed orderly and evenly on the surface of the candidate nodules. The generation of the viewpoint is determined by the azimuth angle and elevation angle. Azimuth angles range from 0 to 2π, and elevation angles range from 0 to π. Since the azimuth angle range is twice the elevation angle range, the initial azimuth angle and elevation ang...
