Guides, project breakdowns, and lessons learned from building medical imaging platforms — written by the PYCAD team.
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.
NTNU and St. Olavs freeze MedSAM3 and train LoRA on 10 TotalSegmentator cases. AMOS22 gallbladder Dice 0.0003 to 0.684. MRSegmentator still leads pancreas. No study code listed.
Balgrist and ZHAW compose frozen TotalSegmentator priors with N=3 MedSAM2 tracks. Hip MRI cohort-average median Dice 0.7105 to 0.9242 on 12 FAI cases. Public TS CT still favors the expert CNN. Claimed GitHub 404s.
Nature Communications published SAT3D on 11 August 2026. Mean Dice is 0.672 versus nnU-Net 0.676. A Swin 3D plus voxel-wise critic feeds confidence maps back as dense prompts. Code and a 3D Slicer plugin are public.
SLIP caches 3D patch features and undoes clicks with 140 MB deltas. Cross-dataset click latency is 0.06 s versus 0.31 s for nnInteractive. MRI uterus still goes to nnInteractive.
CT-ΔBench scores prior-vs-current CT difference reports on 2,638/169 CT-RATE pairs. Zero-shot Change-F1 tops out at 0.0175; DeltaMed full SFT reaches 0.1980.
We build custom medical imaging platforms — advanced DICOM viewers, AI segmentation, and the clinical systems around them.
