The present paper describes a novel recognition method of pulmonary nodules in thoracic CT scans by use of 3-D spherical and cylindrical models that represent nodules and blood vessels, respectively. The anatomical validity of these object models and their fidelity to CT scans are evaluated based on the Bayes theorem. The nodule recognition is employed by the maximum a posteriori estimation. The proposed method is applied to actual CT scans, and two experimental results are shown. |
