Initial acquired phantom dataset for the CT-referenced static MultiWLT workflow in Leipzig. First acquisition: 25 September 2026, Dr. Sebastian Schäfer.
Prefer the three component downloads below; extract them into the same parent directory. The original full ZIP is retained for existing links. It contains 287 CT slices, the source R6 RTPLAN and associated RTSTRUCT, four MVHighQuality RTIMAGEs, four RTRECORDs, the matching analysis profile, CT-fit seeds and an English example report (297 DICOM files; approximately 84 MB compressed).
Patient/operator and local device identifiers were removed or replaced; UIDs were consistently remapped. Pixel arrays, plan control points and contour coordinates were verified unchanged. The de-identified copy reproduced all twelve extra displacement vectors and the pooled sphere exactly. Detailed processing and validation notes are in the archive README and validation.json.
Plan provenance: the source R6 plan is included. The acquired images refer to the separately imported ARIA plan instance; its return export remains unavailable. The matching delivery records corroborate source geometry. This distinction is preserved, and reproduction requires the --records option. Auxiliary references to unshared scanner/segmentation objects were removed. No RTDOSE or experimental arc/couch plans are included.
Use the English MultiWLT guide. Extract the ZIP below multiwlt/local_data, then run:
python analyse.py local_data/MultiWLT_Leipzig_Initial_20260925/MV --profile local_data/MultiWLT_Leipzig_Initial_20260925/RT/reference.json --records local_data/MultiWLT_Leipzig_Initial_20260925/Records --positioned-in-ct --output resultsExpected: 12 pairs, maximum extra 2D displacement 0.5078018875 mm, and REVIEW_FIELD_METHOD for the BB03/G285 field-centre method comparison. This is a research dataset, not clinical commissioning or approval for delivery at another institution. The machine label is RESEARCH_TB and plan status UNAPPROVED.

All component DICOM bytes are identical to the original full bundle. CT/RTSTRUCT anatomy v1 is fixed; future plans can be uploaded as small separate assets with their own matching reference profile. Initial measurements remain bound to R6.
Five-plan collection
All five de-identified RTPLANs (42 kB) · SHA-256. Standard-WLT, R6, BB01-ISO, DCA D2, and combined gantry/couch/collimator alpha (16 fields: four original R6 fields plus twelve G0 variants). All use RESEARCH_TB and UNAPPROVED. R6 is unchanged from the initial release. Other plans have no additional measured results.
Standard-WLT retains a different original CT/RTSTRUCT reference; those anatomy objects are not included. The four head-phantom plans use the stable CT/RTSTRUCT v1 package. The combined alpha plan has geometry checks but no device import, collision-clearance or acquired-MV validation.
Collection v2 replaces the fifth plan; plans 01–04 and the published CT/RTSTRUCT remain unchanged. The fifth plan uses the matching public structure reference. The previous v1 collection remains available for reproducibility. No additional acquired results are claimed.
