Automated detection of lung nodules in low-dose computed tomography
A computer-aided detection (CAD) system for the identification of pulmonary nodules in low-dose multi-detector computed-tomography (CT) images has been developed in the framework of the MAGIC-5 Italian project. One of the main goals of this project is to build a distributed database of lung CT scans in order to enable automated image analysis through a data and cpu GRID infrastructure. The basi...
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 کاملDetection of artificial pulmonary lung nodules in ultralow-dose CT using an ex vivo lung phantom
OBJECTIVES To assess the image quality of 3 different ultralow-dose CT protocols on pulmonary nodule depiction in a ventilated ex vivo-system. MATERIALS AND METHODS Four porcine lungs were inflated inside a dedicated chest phantom and prepared with n = 195 artificial nodules (0.5-1 mL). The artificial chest wall was filled with water to simulate the absorption of a human chest. Images were ac...
متن کاملDetection of pulmonary nodules in chest tomosynthesis
Chest tomosynthesis is a relatively recently introduced technique in healthcare, which produces section images of the chest at a lower radiation dose than computed tomography (CT) and with better depth resolution than conventional chest radiography. The primary aims of the studies described in this dissertation were to compare chest tomosynthesis with conventional radiography, to evaluate the e...
