Live Fluoro In, Preop CT Pose Out Without Patient Retrain
XPos3R takes a live X-ray and a preoperative CT and regresses an intraoperative pose with one anatomy-specific pretrained model, then optional seconds of test-time optimization. Su et al., arXiv:2609.10733.
Click One Lung Tumour Slice, Fix the Ones You Never Touched
LeCor meta-learns case adapters so each clinician click on a planning CT updates the lung tumour overlay on untouched slices, not only the session memory. arXiv:2609.09477.
Sparse FLAIR In, Fusion That Does Not Spoil the Overlay
CoReFuse-Med filters resampling junk on sparse T2/FLAIR in shallow layers and rebalances deep fusion so multi-modal brain overlays stay usable when naive fusion would otherwise lose to T1-only. arXiv:2609.10261.
Cancer Overlay In, Quiet Failure Flag Out From Internal Concepts
FOE hangs the tumor mask, then flags silent segmentation failures from Sparse Autoencoder concepts inside MedSAM, without rewriting the segmenter. Prostate MRI, pancreatic CT, brain MRI. arXiv:2609.08879.
T1 or T1ce In, Shared 106-Region Brain Overlay Out
SpFiLM conditions a 3D U-Net with spatial FiLM so one network parcellates plain T1 and post-gadolinium T1ce into 106 brain regions without a second adaptation stage. arXiv:2609.07718.
Chest CT Alone In, Fourteen Abnormality Overlays Out Without the Report
IGRA anchors each chest-CT abnormality instance to its report finding during training, then drops every text component at inference. Hang the volume, get multi-label overlays for 14 ReXGroundingCT categories in one forward pass. arXiv:2609.00447.
PET, CT, and the Report In: Tumor Overlay Without Dense Attention Blowup
CoMLP fuses head-and-neck PET/CT (and the clinical report) with cooperatively gated MLPs so modalities meet at full resolution before downsampling. Primary tumor and node overlays without pairwise attention matrices. arXiv:2609.04781.
Loose Box Prompt In, Prostate Overlay Out on Speckle Micro-Ultrasound
Approximate box on a 29 MHz micro-US slice in. Frozen MedSAM plus CLAHE, dilation, and Fourier contour smoothing hang a training-free prostate overlay for PSAD or biopsy registration. Point clicks fail on speckle. arXiv:2608.14796.
Pediatric CXR Model Ranks Abroad, Frozen Threshold Barely Fires
Guangzhou-trained pediatric pneumonia AI keeps usable AUROC in Bangladesh and Vietnam, but the locked source threshold drops sensitivity to 6.2% and 0%. Recalibration restores alerts at a steep false-positive cost. arXiv:2609.05140.
Corrupted Slice Interval In, Neighbor-Repaired T1 Stack Out
Flag a bad axial band on a T1 brain volume. SliceBridge reconstructs those slices from intact neighbors with coupled rectified flow and hangs the repaired interval back. arXiv:2609.01827.
