Guides, project breakdowns, and lessons learned from building medical imaging platforms — written by the PYCAD team.
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.
Hang a polyp or skin lesion frame with a short text instruction. InstEditSeg edits the frame with latent diffusion and returns a color-coded overlay on the original pixels. arXiv:2609.02004.
Hang co-registered whole-body PET and CT with organ masks and radiology text pinned to those regions. MetaStructAtlas plus MetaStructVQA give 490 volumes, 50k+ masks, and about 100k grounded QA pairs for PET+CT overlay and multimodal Q&A rails. arXiv:2609.03690.
Hang fully sampled reference contrasts beside an undersampled target. CoSMo-RecNet freezes a public-DICOM content/style prior, trains a light RecNet on a handful of paired raw scans, and returns the reconstructed target for low-field and ultra-low-field brain MRI. arXiv:2609.01959.
Hang a PLAX cine when the apical window is missing or foreshortened. Gao, Yurk, and Abu-Mostafa map that view to study-level EF, with optional A4C fusion. arXiv:2609.02969.
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.
We build custom medical imaging platforms — advanced DICOM viewers, AI segmentation, and the clinical systems around them.
