| Research Abstract |
In this research project, we developed a new intelligent method for computer aided detection of pulmonary nodules in x-ray CT images. An essential core of the method is to use some pieces of radiologist's professional knowledge to achieve clinically demanded high detection accuracy. The results demonstrated that the method can improve 30% of true positive rate for hardly-detectable nodules and reduce 40% of false positive rate compared to previous ones.
