Look at the Structure: Gaze Fixations Become Overlays Without Retraining
Hang a colonoscopy frame or prostate MRI slice, look at the structure. GazeRefine turns duration-weighted fixations into a dense overlay on frozen DINOv3. No labels, no fine-tuning. arXiv:2609.01310.
Untracked 2D Ultrasound In, a Six-DoF Pose on the 3D Volume Out
Untracked 2D ultrasound frame plus a 3D volume in. Rigid six-DoF pose out, no hardware tracker. State-space correspondences then closed-form Kabsch (SCoPE-Reg), IKIM Essen. arXiv:2608.28715.
CT or MRI In, Seven Whole-Heart Overlays Without a Modality Retrain
Cardiac CT or MRI in. Seven chamber and vessel overlays out from one 3D nnU-Net, no modality flag. Label-to-image mix (LISynSeg), Vanderbilt/Mayo. arXiv:2608.31073.
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.
Axial CT Slice In, Organ Boxes and an Auditable Left/Right Call Out
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.
Cine Short-Axis In, Aorta Contours That Hold Through Systole
Short-axis cine-MRI in. Ascending and descending aorta overlays that survive systolic washout. Teacher ED labels, topology scrub, BiConvLSTM student. Public repo.
MedPixel: Phrase or Loose Box In, Overlay and Sentence Out
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.
CoInS-Net: Two Endpoint Slices, One Pass, In-Between Image and Overlay
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.
3D-CurvSegFlow: One 3D U-Net, Three Euler Steps, Three Vessel Trees
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.
CoM3eT Pyramid Transformer Lifts Breast MRI Dice From 0.25 to 0.59
Fraunhofer MEVIS freezes Swin-B and adds a pyramid transformer. Breast MRI Dice 25.28% to 58.62% on 3,936 patients. nnU-Net 33.13% on the full set. Public UNICORN_ENCODER is 2D backbone only.
