4D Lung (segmentation subset) Longitudinal 4D (respiratory gated, phase resolved) fan beam CT of 20 locally advanced non small cell lung cancer (NSCLC) patients, with expert manual RTSTRUCT contours, from Data from 4D Lung Imaging of NSCLC Patients (4D Lung) on The Cancer Imaging Archive (Hugo et al., VCU). This is the segmentable subset of the full collection — read carefully. The full TCIA 4D Lung collection is ~183 GB and contains both 4D fan beam CT (4D FBCT, "4DCT") and 4D cone beam CT (4D CBCT). Only the 4DCT series carry public RTSTRUCT segmentations ; the 4DCBCT series (~134 GB) have no public masks . This mirror therefore contains only the 820 4DCT phase series + the 800 RTSTRUCT series (~46 GB) that form usable image/mask pairs. If you need the un annotated 4DCBCT, download it from TCIA directly.
