3D Computerized Segmentation of Lung Volume With Computed Tomography

Review of automatic pulmonary lobe segmentation methods from CT

“…Most authors here adopt a widely used lung extraction method, which is to search for a large connected region of the air-like values within the image [46][47][48][49][50]. A threshold is chosen using analysis of the gray level histogram, and an initial lung region is then extracted either by region growing from the airways [17] or by finding the largest connected component in the image [46].…”

Interactive Deformable Registration Visualization and Analysis of 4D Computed Tomography

“…Several works have dealt with visualizing the lungs recently involving segmentation [48], bronchial airways ( [30], [28], [20]), and adjusting for motion ([38], [9]). Further work related to motion analysis, the focus of this thesis, will be discussed in greater depth in the next section.…”

Prediction Models for Malignant Pulmonary Nodules Based-on Texture Features of CT Image

“…With technique of computer rising, the computer-aided diagnosis (CAD) has become an auxiliary diagnosis tool (Jiang J et al,2007), especially in diseases that can not be diagnosed efficiently. To improve the accuracy and efficiency of CT screening programs for the detection of early-stage lung cancer, a number of research projects, such as texture analysis (Liu YN et al,2008) and image segmentation (Sun XJ et al,2006), have been done to assist radiologists in diagnosing lung cancer.…”
