Lesion Frame In, Background-Quieted Overlay Out Before Encoding
Hang a lesion frame with cluttered background. FreNet injects a SAM visual prior into the pixels before encoding, reconfigures features in frequency and space during encoding, and returns a cleaner lesion overlay across ultrasound, dermoscopy, and endoscopy. arXiv:2609.03535.
Portable Neonatal Brain MRI In, Seven Artifact Severity Grades Out
Hang a 0.064 T neonatal brain T2. LoFi RADIO distills three foundation teachers into one ViT-S student and returns 0/1/2 severity for seven acquisition artifacts. arXiv:2609.02676.
Low-Dose CT In, Cleaner Stack Out Without Paired Normal-Dose Training
Hang one low-dose CT measurement. PIPG-LDCT builds two physics-driven noisy training branches from that single acquisition, trains a Noise2Noise-style U-Net, and returns a cleaner stack without paired normal-dose labels. arXiv:2609.02654.
Rough Bone Brush In, Refined Ultrasound Overlay Out
Hang a bone US frame, paint a rough brush on the interface. ExiL completes and refines that imperfect mask with a mask-conditioned U-Net and expert-mode updates. arXiv:2609.00473.
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.
