Partial Intraop Ultrasound In, a Complete Lumbar Spine Mesh Out
Partial intraoperative lumbar US bone surface in. Watertight whole-spine mesh out in about 8 seconds. Zero-shot octree diffusion (ZODIAC), TUM CAMP. arXiv:2608.24422.
Guides, project breakdowns, and lessons learned from building medical imaging platforms — written by the PYCAD team.

One axial CT slice plus a binary spatial question. YOLO boxes, centroid geometry, then a 1/0 with an audit trail. YOLO weights ship; VLM checkpoints do not.

Short-axis cine-MRI in. Ascending and descending aorta overlays that survive systolic washout. Teacher ED labels, topology scrub, BiConvLSTM student. Public repo.
Qwen2.5-VL plus SAM2, one reserved token. A phrase or a sloppy ROI hangs a mask and a one-line caption. GitHub exists; weights are still coming.

Shared Swin encoder, physical slice spacing, one forward pass that writes the missing CT or MRI plane and its mask. The preprint lists no code.

Flow-matching 3D U-Net, three Euler steps, same recipe on portal CT, 7 T TOF-MRA, and coronary CTA. The preprint does not list code.
We build custom medical imaging platforms — advanced DICOM viewers, AI segmentation, and the clinical systems around them.
