Abstract:
1. A method for determining if a pulmonary nodule is malignant, comprising the steps of: obtaining at least one computed tomography medical image of the pulmonary nodule; obtaining at least one patient feature of a patient having the pulmonary nodule; extracting image features of the pulmonary nodule from the at least one computed tomography medical image; and evaluating whether the pulmonary nodule is malignant based on an examination of a total of seven of the patient or image features, wherein the step of obtaining the patient features consists of obtaining the sex of the patient; and the step of extracting image features consists of extracting effective diameter of the pulmonary nodule, contrast of the pulmonary nodule, overlap measure of two gray-level histograms for the inside and outside regions of a segmented nodule of the medical image, overlap measure of two gray-level histograms for the inside and outside region of a segmented nodule of an edge gradient of the medical image, radial gradient index for an inside region of a segmented nodule of the medical image, and peak value of a histogram for an inside regions of a segmented nodule of an edge gradient of the medical image.
