OpenBNCT

From geometry to dose analysis

OpenBNCT records physical dose components separately from assumptions about boron distribution and biological response. Researchers can compare each component and trace it to the input data.

1. Define the case.Import DICOM geometry, establish materials and sources, and preserve coordinate systems, units, and input identities.
2. Run or import transport.Use desktop or CLI workflows to prepare and run an OpenMC case, or import external results. The browser workbench is for supported local viewing and analysis.
3. Inspect physical dose.Review boron, nitrogen, hydrogen, and photon components with voxel uncertainty and region-level metrics.
4. Evaluate the interpretation.Apply separately versioned biological models and sensitivity scenarios. Results retain their model assumptions and research qualification.

Available capabilities

The browser workbench opens bundled examples and supported dose files for local viewing and analysis. Files remain in the browser. Case folders and external process execution require desktop or CLI.

These are research capabilities; external validation and roadmap work remain incomplete. The usage guide documents current source interfaces. The handbook distinguishes current-source workflows from packaged releases.

NF-BNCT-001 benchmark results

NF-BNCT-001 is a frozen synthetic case with declared geometry, materials, source, and acceptance criteria. Three OpenMC runs at 600 million histories per seed passed the case’s predeclared statistical gates.

The earlier 300-million-history evaluation missed the photon voxel-precision gate. That report remains published alongside the later passing result. Increasing particle histories followed the benchmark’s declared protocol; the gate was not relaxed.

Remaining validation work

1. Independent transport reproduction.The frozen case still needs reproduction through a separate transport implementation, such as Geant4 or licensed MCNP/PHITS operated by a licensed user.
2. Real-engine adapter acceptance.MCNP and PHITS importers have documented-format conformance fixtures. Those checks do not establish agreement on real-engine cases.
3. External research validation.Broader applicability, end-to-end workflow coverage, and reproduction by other researchers remain active work. Implemented biological functions are research models, not validated clinical predictions.

OpenBNCT is not a medical device and does not establish clinical equivalence or regulatory suitability. Read the use boundary.
