| Abstract(in English) | In this paper, we propose a method of recognition of lung nodules from X-ray CT images using 3 dimensional Markov random field(MRF) models. Shadow candidates are extracted by our quoit filter which is a kind of Mathematical Morphology filters. Other shadows around the shadow candidates are informative to determine whether or not they are actually abnormal. In this method, we formulate such relations between the shadow candidates and the shadows around by using conditional probabilities in the MRF frameworks. The probability of the hypothesis that the shadow candidate comes from a nodule is calculated. The probability for a blood vessel is also calculated. If the probability for the nodule is higher, the shadow candidate is determined to be abnormal. Otherwise normal. Some results acquired by this new method to actual CT images are shown. |
