摘要

Mechanism it is computerized automated for the discrimination of solitary pulmonary nodule between benign and malignant in [challenge] chest image on. Memory (100) a computer for storing computer instructions that can be executed is the method whereby when an instruction is loaded in the computer to program a computer and automated method for analyzing the [SOLUTION] nodules medium is (112). The method, (S10) and to obtain a digital image including a nodule; image intensity contour lines representing the image intensity of each of the regions of interest containing (S20), the nodules to produce a difference image from the chest image nodules based on the contour; (S50) and to segment the nodules to include be identified, and that to obtain the contour of the nodules based on the image intensity contour, to obtain the contour of nodules and determining a likelihood of malignancy of the nodule on the basis of the output of the classifier and at least one; decided to apply to the image classifiers of the at least one feature comprising the features extracted; decided to extract features I include the (S80).
