A New Method for Detection of Pulmonary Nodules

In order to find the pulmonary nodules at the early stage of lung cancer or in duty check, we must detect the pulmonary nodules quickly and exhaustively, especially the small nodules which are often omitted by doctors. A new TMH (template-matching with Hessian matrix) method is proposed in this paper. First lung lobes are gained. Fhen FM (template-matching method) is used to detect the pulmonary nodules. Fhen the Hessian matrix is imported into the method. With this new method, we can decrease the true positive rate markedly. FMH method has been proved to be quick, complete and has low true positive rate.
