MONAI-Physio 2026.09.1

New

• SegmentNVSegmentCT: new segmentation class using NV-Segment-CT, with pretrained weights support (#144)
• registrar() / segmenter() factory methods on tutorial parameter classes — anatomy-tuned registrar/segmenter without hand-building RegisterImagesGreedy/segmenter instances (#145)
• tutorial_00_lung_demo.ipynb: self-contained lung-motion demo, downloads Chest-CT + pretrained PhysicsNeMo-MGN-Lung-Motion checkpoint, runs end-to-end with no prior tutorial dependency

Fixed

• workflow_convert_vtk_to_usd.py: mesh-path lookup now uses sanitized data_basename instead of raw usd_project_name
• Tutorial 3 doc: stale RegisterImagesGreedy() snippet corrected
• Lung tutorials 01–13 updated to use new factories; various fixes accompanying NV-Segment-CT integration
• pyproject.toml: dropped two dangling mypy overrides for removed tutorial_08/09_lung_all files

Docs

• Migration guide for 2026.09.0 API changes
• Tutorial 00 documented in docs/index.rst, docs/tutorials.rst, tutorials/README.md

Other

• Added restrict_deformation_field_to_normal_falloff_outside_mask for cardiac/respiratory slip-interface handling (Tutorial 13)

Notes

• migration_next.md empty for this cycle — no breaking API changes since 2026.09.0.
• This release was used for the Pre-MICCAI hands-on workshop.
