I am working on a project to classify lung CT images (cancer/non-cancer) using CNN model, for that I need free dataset with annotation file. The CT scans were obtained in a single breath hold with a 1.25 mm slice thickness. In order to obtain the actual data in SAS or CSV format, you must begin a data-only request. Invest Radiol. The goal was to investigate the effects of choosing between different metrics in estimating the size of pulmonary nodules as a factor both of nodule characterization and of performance of computer aided detection systems, because the latter are always qualified with respect to a given size range of nodules. The radiologist boundaries were processed and those with four markings were analyzed to characterize the interradiologist variation, while those with at least one marking were used to examine the difference between the metrics. NIH The following PLCO Lung dataset (s) are available for delivery on CDAS. The collections of images acquired during comprehensive lung cancer screening trials have the potential to become valuable database resources.
