Radiation Oncologist Tumor Segmentations The DICOM Radiotherapy Structure Sets (RTSTRUCT) and DICOM Segmentation (SEG) files in this data contain a manual delineation by a radiation oncologist of the 3D volume of the primary gross tumor volume ("GTV-1") and selected anatomical structures (i.e., lung, heart and esophagus). Of note, DICOM SEG objects contain a subset of annotations available in RTSTRUCT.
For viewing the annotations the authors recommend 3D Slicer that can be used to view both RTSTRUCT and SEG annotations (make sure you install the SlicerRT and QuantitativeReporting extensions first!). Visualization of the DICOM annotations is also supported by the OHIF Viewer.
Other tools include: - Dicompyler is an open source, cross-platform DICOM RT viewer.
- The Radiotherapy DICOM toolkit, which may also be useful for working with this data.
- dcmqi and Plastimatch libraries can be used to support conversion of the DICOM SEG and RTSTRUCT representations, respectively, into the popular research formats, such as NIfTI or NRRD.
Clinical DataCorresponding clinical data can be found here: Lung1.clinical.csv. Please note that survival time is measured in days from start of treatment. DICOM patients names are identical in TCIA and clinical data file. |

- RTSTRUCT and SEG study instance UID changed to match study instance uid with associated CT image.
- Added missing structures in SEG files to match associated RTSTRUCTs.
- Patient Id copied to Patient Name in CT images (for consistency).
- Added 1 missing image for LUNG1-246.

- Re-checked and updated the RTSTRUCT files to amend issues in the previous submission due to missing RTSTRUCTS or regions of interest that were not vertically aligned with the patient image.
- In 4 cases (LUNG1-083,LUNG1-095,LUNG1-137,LUNG1-246) re-submitted the correct CT images.
- The regions of interest now include the primary lung tumor labelled as “GTV-1”, as well as organs at risk.
- For one case (LUNG1-128) the subject does not have GTV-1 because it was actually a post-operative case; we retained the CT scan here for completeness.
- Added DICOM SEGMENTATION objects to the collection, which makes it easier to search and retrieve the GTV-1 binary mask for re-use in quantitative imaging research.
- Clinical data updated as follow-up time has been extended.
