Computer Aided Diagnosis For the Detection of Lung Nodules
Lungs segmentation is a vital step for computer aided diagnosis. Many lungs diseases requiring radiological support for diagnostic purpose, including tuberculosis, emphysema and lungs cancer could be affectively diagnosed using computer-aid. Pulmonary nodules usually act as the early stage characterization of lung cancer. It’s a crucial way to control the disease and reduce the mortality by fur...
متن کاملComputer Aided Detection of Lung Nodules in Multislice Computed Tomography
Early detection may be of critical importance in lung cancer prognosis. Multi-detector Computed Tomography (CT) increases sensitivity in early lung cancer detection by potentially identifying nodules of smaller size. A Computer Aided Detection (CAD) system for automatic identification of lung nodules is proposed. The system is multistage, including segmentation of lung boundaries, initial nodul...
متن کاملComputer-aided detection of lung nodules using outer surface features.
In this study, a computer-aided detection (CAD) system was developed for the detection of lung nodules in computed tomography images. The CAD system consists of four phases, including two-dimensional and three-dimensional preprocessing phases. In the feature extraction phase, four different groups of features are extracted from volume of interests: morphological features, statistical and histog...
متن کاملImproved detection of lung nodules on chest radiographs using a commercial computer-aided diagnosis system.
OBJECTIVE The aim of this study was to evaluate the usefulness of a new commercially available computer-aided diagnosis (CAD) system with an automated method of detecting nodules due to lung cancers on chest radiograph. MATERIALS AND METHODS For patients with cancer, 45 cases with solitary lung nodules up to 25 mm in diameter (nodule size range, 8-25 mm in diameter; mean, 18 mm; median, 20 mm...
متن کاملA Computer-Aided Diagnosis for Evaluating Lung Nodules on Chest CT: the Current Status and Perspective
As the detection and characterization of lung nodules are of paramount importance in thoracic radiology, various tools for making a computer-aided diagnosis (CAD) have been developed to improve the diagnostic performance of radiologists in clinical practice. Numerous studies over the years have shown that the CAD system can effectively help readers identify more nodules. Moreover, nodule malign...
