Automated Lung Segmentation and Image Quality Assessment for Clinical 3-D/4-D-Computed Tomography

J. Wei, G. Li

4-D-computed tomography (4DCT) provides not only a new dimension of patient-specific information for radiation therapy planning and treatment, but also a challenging scale of data volume to process and analyze. Manual analysis using existing 3-D tools is unable to keep up with vastly increased 4-D data volume, automated processing and analysis are thus needed to process 4DCT data effectively and efficiently…
